I have a 4dr LS and would like to get the Apexi WS.. However they are only made for 2dr ls, 2dr GSR and 4dr GSR. Since the GSR's have shorter cats could i use a 4dr gsr cat and 4dr gsr exhaust??
Please only respond if you know for sure.

Thanks

Yea you can get a apexi WS for a 4dr gsr and jus cut off some of the piping. I don't think you should use a gsr cat since it won't fit your exhaust manifold/header. The gsr cat will either be too short or too long.

 

i mean use a gsr cat with a gsr 4dr exhaust.

 

Even if you use a gsr cat, your existing b18b exhaust manifold/header won't match up with it as far as length that is.

 

Make your own also get a es oval muffler and carsound cat's and at least Type R sized pipes

 

so what you're saying is LS and GSR's manifold, cat, exhaust are all different lengths? and the best way is to get a gsr 4dr catback and shorten the bpipe??

 

Since I have already done this research, for my 4-Door SE

5-Zigen Firball
Skunk2
Greddy SP
and I beleive Thermal may also

The Greddy SP would be your best bet for the type of style, sound, and with minimal modifications to fit. But if you insist on the WS then you may have to take it to the muffler shop to shorten or cut.

 

which exhaust did u go with??
i want something quiet...

 

nothing from thermal..

 

a stock one would fit with no modifications.

 

then whats am i doing all this research for? well of course it fits... its on the car..

I went with the 5Zigen, but for you as I suggested, should go with the Greddy SP if you want something quiet

 

use that 4dr gsr exhaust you mentioned above...and i have a dc 4-2-1 ceramic header for a gsr, along with the cat..to replace your ls stuff...your o2 sensor will be about the same location...just in the front of the cat..PM for pics
