RV6 V6 J-Pipe - 8th <--> 9th ?

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 hope it's soon lol the waiting sucks
I'm excited for the pipe but I'm wondering how much louder it will be. I don't want my car to be loud where everyone is looking at you cause your car is so loud lol
Well I have always planned to keep my main cat except just change to a high flow even if it has to be welded in. I had planned to delete the pre cats just because I'm sure they choke the engine out of a bit of power but like you said a pipe and pcd's could get pretty loud. Might have to decide on one or the other..
Electric cut outs? I'm not following..
That's true, I have not decided If I should get high flow pre cats and the jpipe or no j pipe and deleted pre cats.. Which ever one that would be quieter
