Do you have the primera motor, if so the stock header(exhaust manifold) has a wider diameter pipe than the us spec sr20, and far less restictive *almost* like a performance header. See if you can get a muffler shop to custom make a down pipe for the exhaust manifold, instead of cutting it. Works great if your going for the sleeper look........

cutting it would be cheaper than fabrication a downpipe...the internal diameters of the two seem almost the same...i havent measuered it, but by eye, they look almost identical.

by cutting it you mean to shorten the length so it clears the bottom and wont bottom out?
if they can do it it probably would be cheaper, i decided to go custom because i wanted the sleeper look and the down pipe i had made is tucked higher than the crossmember so i dont have to worry about it hitting...
