So,

A little background...
Me and my best friend were fortunate enough to both own 6-6 black coupes. I had a 2007 and he had a 2008. I have since sold the 2007 and purchased a new EX-L V6 coupe 6AT (unfortunately MT are so hard to find). So now he is selling his 08. Before he does that I am trying to snag all the parts off his and put it on the new baby. So far I have successfully swapped over the Takeda intake with minor modification and a Progress Tech 22mm rear sway bar with end links.

Now onto the next item of interest....

I am trying to figure out if the RV6 J-pipe for the 8th gen will fit on the 9th gen. After some preliminary measurements it looks like its the same pipe. All the dimensions seem to line up. The only difference is the O2 sensor in the 9th gen (8th gen doesn't have an O2 in the J-pipe). So my next goal is to try and switch the pipes. If both pipes can be switched successfully, I will then consider bringing both pipes to an exhaust shop were I will add an O2 sensor mount for the RV6 J-pipe, and I will have my 9th gen stock J-pipe sealed up to put back on the 8th gen.

Has anyone else tried going down this road, or have any information on this topic? I have also contacted Rich from RV6 regarding my theories and ideas.

Note: The only major difference in the Resonator. The 8th gen and the 9th gen seem to have different designs, but I think they are the same overall size. I will confirm this when I try and switch the pipes over to see if they will fit.

I think rich would be the best person to get an answer from. I'm currently testing the prototype RV6 PCD/down pipe

Are you testing the V6 downpipe, because I know there's a separate thread for the I4 downpipe. I'm going to see what happens with the J-pipe first, then I may consider some mods to the down pipe. My one worry is that if you remove the down pipe cats, your going to overload the only cat left which may make it wear out faster. Maybe Im just being crazy.

Im actually considering wrapping the down pipes to take some heat away from the engine compartment now that I have a short ram intake.

I am in contact with Rich via email. Once he comes back from Sema we will chat more about where to go from here. I think I will try to remove both pipes from the 8th gen and the 9th gen to confirm exact measurements. I will try and test fit the pipes to confirm. If indeed the 8th gen fits on the 9th gen, I will try and bring it by an exhaust shop to mount the O2 sensor in the 9th gen setup, and have the sensor hole covered for the 8th gen swap. I will report back when I start getting into the nitty gritty of it all.

I know you can do it. Someone on instagram put an 8th gen rv6 j pipe(v6) on a 9th gen. but had to relocate the o2 sensor and the hangers aren't the same.. I believe his instagram is torinmarkel.

sounds amazing.

Im sure it will fit. The only issue is that if you have a regular shop weld on an O2 sensor mount the weld joints wont be as good of quality as RV6 machine welds. I just feel bad cutting into a top quality stainless pipe and putting sub par welds in it.

Same reason I am having a hard time adding the "through pipes" to replace the mid muffler and resonator because the stock exhaust is fairly nice quality stainless steel.

Hopefully the jig and/or program to bend the piping can stay the same and you will just have to move the hangers a little and stick an O2 bung on it for us :)... The PCDs from 8th gen look like a direct match too.. :)

If it's not too late, maybe consider making the merge more like the competitions pipe? More of a shallow "Y" configuration? Either way I'm going RV6, just an opinion :)

Now comes the stupid question... why is that thing good for the V6 or just good in general?

What's are the benefits, are are the downsides? Will it generate more drone, noise or something else?
