Hey guys and gals,

After lots of consideration and reading on Acurazine, I found a cheap mod that will help your cars sound a lot better without making the car any loader or sounding like a rice rocket.

Sorry, but this is only really for the V6 guys and the 6MT guys will probably appreciate this the most.

Here is the link (http://tl.acurazine.com/forums/showthread.php?p=1582580#post1582580)

I did not do a mod writup as it's not my mod. If you want, I will repost it here, but I wanted to give credit where it was due.

I only did the state 1 mod. I just deleted the "mid muffler" out of my system, and let me tell you, the exhaust note is so much better than before. Before, our exhaust systems did a great job covering all of the sounds, but this lets some of that rumble come out. It's the sweetest between 2-3k.

The cost for me=35 dollars at an independant muffler shop!.

Any questions, hit me up, but that thread will tell you everything you need to know.

sound clip?

Can y'all click on the link? I wasn't sure as I'm a member and you all are not. If it doesn't work, I'll repost the information as they have links of the different stages of sound. Let me know and I will repost it if you'd like.

Worked for me I think. You're tallking abou thte clips that aznbo187 posted in the thread from your link, right?

Yup, that is the condenssed DIY. The clips explain the steps required to induce the sound.

From what I remember, the 7th gen V6 has a very similar exhaust system, so I would imagine that both would sound very similar.

I would imagine the AV6 to sound more raspy than throaty since it has a smaller displacement engine. It doesn't matter anyway since I like my quiet exhaust. :)

Do people really like how the G35 sounds? I find the VQ engine to sound really annoying...

the "G35 sound" sounds very.....unsubstantial. like some artificially engineered noise/whine rather than what a powerful motor should sound like.

I just figured I'd put this out. I did the stage 1 mod, which is just removing the "mid muffler" out of the system. You really can't tell unless the windows are down and you are in the 2-3k rpm range. It just sounds nicer. Windows up, no difference in the car.

So far, I'm a big fan. One of the few things I wanted in the TL. I figured the 6MT model should have an exhaust sound every once in a while.

Hmm something I'll probably consider down the road, but want to wait as my car is still just a "baby" and I don't want to do anything to the warranty unless I feel I have to. Also depends on how much money I have down the road, as I might just splurge and go full catback system or something.

I find it hard to believe some people in here don't like the G35's exaust note. Atleast imo its one of the best sounding stock systems out there right now, esp when compared to the Accord. I will admit though having a near silent exaust system is nice at times though, as there have been a few times were I have gone past a cop (or approached a cop) above the posted limit, and since he didn't hear me coming (plus the fact that its "just an Accord" and with my HFP setup I can brake without the front dipping much) they never even flinched.

Thanks Stevencrosbie for posting this. :thmsup:

If you can tell me how to delete engine noises altogether THEN I would be interested!! lol.. :thmsup: :yes: :biggrin:
.

Thanks Stevencrosbie for posting this. :thmsup:


No problem. I figured you'd enjoy this. :nuts:

Oh...yeah...the TL isn't as stealth...so I have to be careful not to draw attention from cops. :paranoid:

i was saying, do you happen to have a sound clip of your car and a g35?

i couldnt find one in that thread in acurazine

Compilation of all stages of exhaust resonator modification.

So far, there are 4 stages of this exhaust mod.

Stage 1.
Least noticeable in exhaust note increase.
Configuration:
Stock exhaust.
Remove mid-muffler. Replace with 2.5" straight pipe. Everything else remains stock.
Cost: Can be anywhere from $30-$60 w/aluminized pipping.

Stage 2.
A tad louder than stage one, a bit more pronounced tone.
Configuration:
Stock exhaust.
Remove mid-muffler. Replace with 2.5" straight pipe.
Remove stock resonator. Replace with Magnaflow resonator part# 10416.
Magnaflow resonator is a 14" long resonator, which dampens and changes the note of the stock exhaust a bit more, thus you get a bit more loudness/tone.
Cost: Magnaflow resonator costs around $60. Install ranges from $60 -$90 w/ aluminized pipping.

Stage 3.
(Tone result TBA)
Stock exhaust.
Remove mid-muffler. Replace with 2.5" straight pipe.
Remove stock resonator. Replace with Dynomax resonator part# WLK-24215.
Dynomax resonator is a 12" long resonator, which is a bit shorter and less dampening than the magnaflow resonator, thus it should give you a bit more loudness/tone than stage 2.
Cost: Dynomax resonator costs around $40. Install ranges from $60 - $90 w/aluminized pipping.

Stage 4.
Loudest setup out of all 3. Has a bit of a rasp, similar to M3 exhaust setup.
Stock exhaust.
Remove Mid-muffler. Replace with a 2.5" straight pipe.
Remove stock resonator. Replace with a 2.5" straight pipe.
Cost: Can be anywhere from $40 - $60.

Alright, like I said, this is not my mod. I took it from aznbo187 from Acurazine. Amazing study so far and he will update it with the stage 3 mod when he gets time.

I have the stage 1. Just the mid muffler removed and I think that is all I want. I never wanted a noisy car, but I did want a little deeper sounding exhaust and this has done it. You have to listen though to hear it, so most people will never even notice (includes dealer/people who you might sell the car to later on).

The links do a pretty good job capturing the sounds. I can do mine, but probably will not happen for a couple days. These are just as good though.

Watch out, those of you in the north - salt will eat right through cheap aluminized steel. After watching this happen on one of my older cars (aluminized replacing a section of my OEM stainless steel exhaust system) I'd never consider it as long as I lived up here.

BTW Stage 1 sounds cool, but as you move up the stages it just sounds kinda ricey... I don't know, I'm particularly sensitive to it (I hated how my old Civic sounded, even totally stock), but I just don't know why you'd buy a car like the TL to make it sound like that. If you like it don't mind me, I'm just a cranky old man.

Yeah, I don't care for the others either. That's why I just did the stage 1. You really can't tell in the car unless a window is down or you turn the sterio off.

Just right if you ask me.

kinda goes with this

http://www.v6performance.net/forums/showthread.php?t=79902

read it and watch the vid, pretty cool

electronic deally that switched it from stock to throaty exaust

Hmm...I will admit after listening I do like Stage 1. Stage 2 is "ok", then 4 is just way too raspy for my tastes.

GRdotNet kinda hit the nail on the head though...my primary reason for not doing this right away is largely due to the fact that this is a "show mod" only really (doesn't increase your hp/tq really) and also adds to the chances something could rust out on you down the road, esp for those who live with salt for so many months of each year.

For anyone who is interested, I've attached a pic below of a 7th gen V6 Accord coupe's underbody (sedan should probably be the same) with the same parts labelled as the TL in the pics Stevencrosbie posted:

http://i42.photobucket.com/albums/e313/Conundrum1911/AccordV6UnderbodyExaust.jpg

In case anyone is wondering, I pulled the pic from Honda.com's website by capturing a still from the "expanded" 3D view of the coupe. :D

i pulled my 3rd cat, resonator and premuffler. stock exhaust. i get compliments from everybody.

Do people really like how the G35 sounds? I find the VQ engine to sound really annoying...
i don't. i think they sound like a man gargeling mouthwash or even like chewbacca. later.

I can't stand for the stage 4....the sound make me sick

but I like the HKS TL thou.

yeah stage 4 sounds really horrible. the HKS sounds sweet. so does the comptech.

(i found this video on acurazine a while ago and saved it to my computer. dont remember who car it is or who took the video.)

I vote for the comptech one... sounds nice and ain't rice! :banana:

Had Stage 1 done to the car this afternoon. Its actually a very mellow mod.

You definitely hear it on start up, but its subtle - there's a wonderful deep growl that lessens as the revs settle down. Sounds great upon accleration, but disappears (to my 50 y/o ears) above 2000 RPM.

Crusing around town or on the freeway, tire noise drowns out the mod. No drone on the highway. I stood behind the car at idle and couldn't hear much difference from stock. The mod's interior sound is nowhere near as loud as it appeared in the Stage 1 video example.

The wife was right, its not hooligan enough for me, so Stage 2 (Magnaflow resonator) is on the way. But this is a great mod for those who just want to know the exhaust is there. :D

I had the mod done by Muffler Time on Dawson Dr. in Camarillo California. Great little shop that's been around for ages. Charged me 30 bucks.

Also stopped by the Acura dealership and ordered a 17mm TL swaybar and related parts. Can't wait for that!

I had the stage 1 done to. Much more improvement over stock sounds. I am a big fan and I love the sound.

If you want to have some fun, open a window. Between 2-3k sounds like the car should. :banana:

The rest of the time, you can't tell. Close the windows or have any radio sound at all and you can't hear anything :lmao:

wow, I love the stage 1 soo much, If I keep my car for another year I will add it on for sure, especially because its so cheap, 30-60 bucks, Nice :thmsup:

As I reported above, Stage 1 was not enough for me, so I had the Stage 2 mod done to the car this afternoon. Rick Stout, the owner of Muffler Time in Camarillo, just laughed when he saw the big 'ol Magnaflow resonator. "You're in for it now", he said.

This install did not go as quickly as Stage 1, because rick had to fabricate some adaptors for the larger openings on the resonator.

After about 30 minutes, the job was done and we all held our breath as I started the car, expecting VA-ROOM! Instead, we heard Va-room.

The wonderful deepness and subtleness of Stage 1 remains, but is more there and only slightly louder. The sound at idle was still barely perceptible, but blip the throttle and it suddenly comes alive, sounding very G35-ish.

Pulling away from stop signs and tooling around town, the sound is again only moderately louder than stage 1 and I found myself having to listen for it at times. The mod can still get lost in the road and tire noise on the freeway. I climbed the Camarillo Grade on Hwy 101 at around 75 mph and the interior of the car remained comfortable and quiet with no drone, rasp or rice.

Overall I'm real happy this time around. Those of you (myself included) who admire the sound of a G35 accelerating from a stop will be happy with the sound that the Stage 2 produces, which is very classy and fitting with the image of the Accord. :thmsup:

Maybe you're right. I had the 17mm bar installed last Friday and frankly, I'm underwhelmed. Can't say that I noticed much difference in roll stiffness betweent that and the stock bar. Others on the board have had better results.

Do I just replace from the 3rd cat on up to the pipe splitter with 2.5" piping? would it be better to go with 2.25" piping to make sure I dont lose too much backpressure?

Ok, i just joined this site, so therefore heres the late reply, but i just cant get over this freakin sweet exhaust set up. I cant stop druling over this, which was found in the first post with the link. I come from previous domestic muscle car experience and this definately catches my eye. Too bad i dont have a V6. LOL :jawdrop:

http://i43.photobucket.com/albums/e358/flydealz/6365Custom_Exhaust_002.jpg

I still love it in the TL. It attracts a lot more attention by people watching me pull away and I love the sound.

Gotta say...best mod to my car yet.

Too bad you have the 4...but welcome to the site!

anyone try this on the i4 yet?

Hey guys,

I'm a new member and I was about to do the stage 2 on my 03 accord v6 coupe, but then when i took my car to the exhaust shop, they told me it would sound exactly the same if i just switched the resonator. I ended up jumping from stage 2 all the way down to stage 4 lol. I don't understand why on video it sounds so raspy for the tl's, but for my car it sounds pretty damn quiet. It sounds only a little louder than stock. It has a slight G35 sound to it as well. There's no rasp at all...AT ALL. So if anyone wants to know, i removed both the mid-muffler and the resonator and replaced both with 2.5in straight piping.That's my experience...hope it helps some people make decisions.

To be honest I like the sounds that come from a 330i over the Infiniti. It does sound a bit artificially engineered.
