GST Downpipe?

I just bought a 1990 Eclipse GST and I was looking to buy a aftermarket exhaust blow off valve and downpipe and I've found the exhaust and BOV I want but I'm having trouble finding an aftermarket downpipe. All the downpipes I seem to find are for the GSX AWD model only. I was wondering if anyone had any suggestions as to where I could get a decent downpipe for my GST?

Also, be sure to keep that stock diverter. You don't need to upgrade it until you start running some serious boost.

Make sure you get a recirculatable BOV.

Do all the "free mods" first and hold off on a downpipe for now.  Get a nice cat-back exhaust instead.

my bov is not recirculated. and my car is fine.

Do you have a wideband?
 
If so, shift at redline, and tell me what your A/F ratio says when you get back on the gas. I guarentee it will be in the 10's and never recover.

at 8k im not sure what its at. my cars not out yet so i cant tell you right now. but i will get back to you.
