I was wondering if the s pipe and muffler from a coupe will fit a 4 door? anyone know?

I know the catbacks don't interchange, but I forget if it's the muffler, B-pipe, or both that's different. It's called a B-pipe for future reference.

I would recomend buying the catback thats made for your vehicle. trying to make one fit will just be a hassle and probably not turn out nice

I was just wondering if the S pipe and muffler are the same for a 4 door and coupe because I already have the straight pipe and only need the s pipe and muffler from a greddy sp.

The S-Pipe as in the part where its curved like an S? If so it should fit as well as the muffler. Only the tip will be short as the 4 door has a longer trunk and bumber.

However where the B-pipe (what its actually called) connects to the cat converter, it will be short as the 4 door has a longer wheelbase. Just add some extra piping and you'll be fine.

It would be easier and more trouble free to get the proper parts.
