Hill's Garage GTM Stage 2 Supercharger Direct Port Methanol Dyno

What type of exhaust are you running from the headers back? I'm trying to figure out if there is a trend with the guys making 500+whp on superchargers and their cars with the type of exhaust they are running. I'm running long tubes (think I'm one of maybe a couple running LTH's and SC's?), MD Y pipe (resonator currently) and Tanabe exhaust.

When I was originally tuned for 543whp, it was with resonated test pipes and the Invidia Gemini exhaust, on methanol. 510whp was without methanol and a couple degrees of less timing.

I still have the test pipes, but I switched the Gemini out for the Motordyne exhaust. When it was retuned, it really didn't make much of a difference power wise. I did it more for the sound than anything.
