You can always just buy one of these and adapt it to your stock exhaust system, but would require the starter relocation, which if you get the GT tranny will already be set up for it. http://www.ebay.com/itm/OBX-Racing-...&fits=Make:Toyota&hash=item27d413f3d7&vxp=mtr racerb
Hmmm I recently found a guy in australia breaking an ST162 that has custom headers that I can get for like 280 shipped. If that doesnt work out I may go this route!
I have a fully custom made flange, to muffler system- I may sell? Not sure what kind of power you are making? It is stainless steel 4-1 headers, and v-band gasketless connections on 3" front pipe all the way back. A custom modified Borla muffler, a test pipe and cat (interchangeable). I spent a mere $5500 on the exhaust!
