Stock exhaust comparison/questions

[FriendOf2Accord]

Hey guys, I was just wondering what the piping diameter is on the 6th gen f23vtec Ex coupe? What about the 6th gen v6 coupe?

Also, will the stock cat-back from a v6 coupe fit on an f23 coupe? I know the headers and stuff are differant, but wondering about the midpipe and dual outlet will fit.

2" 4cyl

2 1/4" v6

Why would you put dual on the 4cyl?

For the added exhaust flow without the unwanted sounds of aftermarket exhausts.....

You're gonna be losing a lot of power with the other muffler.

If you want exhaust flow, get the pipings. Cut where they split into two and weld something to cover the hole.

Too much work for no gains tbh. Get custom pipings done, install an aftermarket resonator, and have them install some flanges for your stock muffler incase you want to change it in the future.

I also don't know if the hangers are the same for 4cyl and V6 also.

I dont think going from 2" to 2.25" with stock mufflers is going to kill the "precious" backpressure nearly as much as 2.5" with straight through muffler....
