Re: header help again

Measure your pipe and try seaching through these for your size

Re: header help again

should not be more than $80. i had mine done at marco muffler here in town but i had them cut off the stock size flanges to mate to the shorties and ran 2 1/2 y pipe back.

Re: header help again

when i had mine done it was all custom from the headers back. y-pipe, high flow cat, to a 40 series duel out, all te way back 2 1/2". $650... and yea i know thats alot but if you seen the work you would understand... the only thing i didnt have them do was use stainless. live and learn!

so i dont know what the $ for just the welding of new flanges was...
