Thanks.
So, am I correct in thinkin the meth kit gave ya 30-40 more hp? Very high 400's, just like Zavier said.
Yes,originally we were getting 450 wheel hp with a 3" exhaust @ 16-17 lbs.
I put the resonated mid pipe back on with this setup so we lost 20 hp but is not really loud until the wastegate opens up.
