I don't regret getting the headers at all, except for the cost/benefit ratio. The sound is glorious! I'm sure a true dyno tune would find more power but flying Jerry to P.R. just isn't cost effective ….. maybe I should give him a call and ask ….. humm. Anyway, talk to Paxton, he installed the same headers along with 550 cc injectors and got a dyno tune with great results.
