Just out of curiosity...Will a Greddy SP exhaust from a 2 door GSR fit a 4 Door gsr with modifications? If so, what kind of mods need to be done? I'm under the assumption that I can extend the main pipe off the cat 4 inches and it should mount up...ANyone?

 

I believe you are correct in assuming the addition of the four inches. I bought a 2dr Magnaflow exhaust and they sent me a 4dr. I took it to a shop and got exactly 4" cut from the pipe that connects to the cat, and everything fit up fine. I'm guessing that magnaflow's muffler and S pipe pieces are the same for the 2dr and 4dr, and they have two seperate resonator pieces, the 4dr being longer than the 2.

But I don't know any specifics of the Greddy.

Same thing. You're right. Add a few inches and you're good to go.

 

i bought a tanabe racing medallion..for a 2dr..i have a 4dr gsr..went to the muff show..hung everyting by the factory hangers..and had to add 1.5" to 2" piece in the pipe near the cat...

 

Thanks everyone.
