although i don't know for a fact, i heard that that was only the DOHC headers and they were redesigned because of it. contact hotshot to confirm.

i've seen it done, hard but not impossible, i won't do it to a lowered car though. hell the 93-95 SL2 rear bumber almost looks like it was designed for a dual muffler.

bingo. backpressure = lowend torque


also, with all this engine work, i assume you are also considering brake and handling upgrades?
