I have a restriction in my GMMG.... the i-pipe was changed because it was to loud after i put in the headers. Anyway before cam 307 HP after 342 HP with and A4, Don thinks i'm losing 20+ HP through that i-pipe, so looking to fix that. But as every one knows A4's with a stall (not dyno queens) will cause alot of parrasitic loss and it's more important on the track....... on Slowhawks dyno 1/4 run 1.7 60 ft. 12.2 @ 109 MPH and since it's a 99.9% street machine i asked Don to tune it more for pleasure then Strip use

What did you do put a bullet muffler in the i-pipe? It shouldn't loose to much power. What size headers? I thought the GMMG with LT's and cats sounded great. Without cats it's pretty loud, but I gained 1mph at the track without them
Yeah you can't base it all on dyno numbers on stalled autos. The car will move out, believe me.
The Small Cam gained almost 40hp but going over the graph show's me an exhaust restriction.The I-pipe is crimped like the catback is.I wanted to run open Y-pipe but didn't have time before it was picked up.
