So after reading multiple threads and 100’s of opinions on what improves performance and what doesn’t, I wanted to get opinions on if y’all think Ktuner/Hondata tune + PRL Downpipe would be a good start and if so, should I get a new exhaust system to go with the downpipe upgrade ? Just for reference, I am going for power, not strictly sound, not trying to get crazy with it, but would like my car to feel and sound more fun. Basically I don’t want to make unnecessary upgrades on performance if it really won’t make a difference, because after this I want to focus on cosmetics. Any feedback or recommendations would be appreciated, thanks !

IMO you want a power upgrade. Gotta do the motor work. Turbo upgrade... All that other stuff can fall in line after that. If you want to notice something..... Im thinking otherwise you might not really "feel" the difference you see on paper with all the other stuff.

IMO, I would agree with the above, but definitely start with a tuner. That way once you do the upgrades to the hard parts, you already have the access to re-tune to the new parts, and you'll get a pretty noticable power increase from the tunes to begin with. I only have a little experience with Hondata's software, but there is a lot of options available and there is the possibility of custom tunes as well. Again, just my idea.

You can see my sig. Not a ton spent, and at this point, it will not keep traction unless it is dry lol. No need for more power IMO because it won't hold the road. I can stomp it now even on dry pavement around 40mph and break them loose a little as it spools up. It is very fun to drive though, I leave it in sport around town and it is peppy.

I could see bigger power as a track car, but for a daily driver it is fun as hell with the mods I have I sounds good too.

Have you done this upgrade yourself ? Everything I read about these CVT's in our cars makes me nervous to add a whole lot of power to it.

Appreciate the response, I went ahead and ordered K-Tuner V1.2 along with PRL Downpipe (with cat), super excited to see how it feels afterwards.

Thanks for the response, I ended up ordering Ktuner + Downpipe, excited to see the results. Do you think getting new tires would help or is it just us having FWD ? I will be getting new rims/tires anyways so possibly that will help.

Not sure on the tires. The enkei wheels I added are about 8lbs less per wheel than factory, so I am sure that freed them up some. I plan on replacing these goodyears with michelins when I wear them out.

While I can't answer that, I can say that it is not advisable to significantly increase the load on the CVT. Manual drivers occasionally complain of slipping clutches with significant tuning (above 220-230hp) on the 1.5. Clutches are allowed to slip here and there without damaging the transmission. A minor performance tune via Hondata or Ktuner would be the better way to go. Otherwise consider trading in for a 2.0t so you can drive a car with a transmission designed to handle 30% more power from the factory.

I might get blasted for this, but I think if you wanted a tuning platform, you should have went with the 2.0T and the A10. If you are talking about tuning, exhaust upgrades like downpipes and high flow cats, and maybe even a turbo upgrade, you are talking about thousands of dollars. Not to mention a tune voids your powertrain warranty if your engine blows up and then you are on the hook for more financial stress. No matter what you do to the 1.5, the 2.0 will be faster. Not solely because of the engine, but because of the transmission as well. The A10 keeps the 2.0 in the powerband pretty well. The CVT does a decent job as well, but I haven't heard of a single CVT that can hold power. From a financial perspective, it's a mistake. If you just wanted to do something different, I can respect that. Nothing wrong with that at all.

can anyone point me the right direction?, been looking for a aftermarket downpipe for a 2021 accord sport 1.5, seems that the ones for civics won’t fit on accord, even the turbo is different or correct me if I’m wrong, thanks

I have the aftermarket PRL high volume down pipe that was made for the 2022 Honda Civic 1.5 -T on my car right now. The PRL high volume down pipe for the 2018 - 2022 Honda Accord 1.5 -T and 2022 Honda Civic 1.5t are exactly the same. Mine is awesome, I would buy that one. Worth every penny. 2022+ Honda Civic 1.5T PRL Motorsports High Volume Downpipe Upgrade 2022+ Honda Civic 1.5T High Volume Downpipe Upgrade

How do you think the 1.5 acts and performs in general? I am on a few facebook pages and i’m constantly see people having issues with these cars and it makes me nervous to own one. Like fuel injectors at 40k miles, leaking engines, blown heads, etc. Cant help but wonder about the oil dilution issues. For reference, I have a 2021 Accord LX 1.5
