Thanks for the offer. my dyno tests showed 10whp gain and about 15wtq on a dynocom. How were your headers after dyno? I now have a secondary cat delete too. The smell of exhaust with the windows down is intolerable. Same thing for you? I will dyno again to see what the secondary delete did.

I will be able to churn these out quite rapidly if this one last test goes right. Like Michael Corleone's papa said. It will be an offer no one can refuse.
