Re: Bizarre Herrod conversation today
Mate, from the cat back is twin 2 1/2".. the restrictive part is the cat.. Ask him where he gets his information from, based on what results.. Also ask him what he reccomends as a replacement exhaust ( just to humour him ).. twin 2 1/2 is equal to a 3 1/2" single, so he'd better be backing a 4" drain pipe in his package, if he wants to improve' your exhaust flow... Remembering by the time it gets back there, it's cooled off and 2 x 2 1/2 is plenty for just an edit/injector combo..
Maybe he'll tell you they have 'hi-flow' mufflers or something..
Dump pipe and cat maybe a worthwhile replacement option, if they do them, but by the looks of their site they don't.
BTW, their cat back exhaust on average gives an 8rwkw gain over stock..
Tell them what YOU want, not the other way round.
