APEX N1 downpipe problem

[sillyme]

i put it on and found out it doesn't fit my stock exhaust. i own a 1990 eclipse GSX. the hole on the downpipe is much larger than the stock exhaust diameter. is the apex n1 exhaust the only one that fit this downpipe? and is the exhaust the same diameter as the downpipe with no shrunken pipe sections? last, i heard with the dp and exhaust on that the boost will be around 17psi. is that too much for a stock fuel system?

Apexi exhausts will bolt directly to Apexi downpipes and eliminate the cat, and to the stock downpipe/cat using the adapter. Apexi downpipes won't bolt to the stock downpipe. Besides, you should upgrade your exhaust starting from the muffler end and moving forward, not the other way around.

yeah, what sucks is i need to find a downpipe that will fit on a HKS exhaust..

Hell they should all be universal!
