Guest kev21 Posted February 2, 2010 Share Posted February 2, 2010 will a 2 collener on mainfold with 2.25 decat back work good Link to comment Share on other sites More sharing options...
HotRod_07 Posted February 3, 2010 Share Posted February 3, 2010 no it will be restricted if you get 2inch. just get 2.25 becasue if you get 2.5 it will still be restricted at the decat to 2.25 so you wont see any extra power gains Link to comment Share on other sites More sharing options...

Solidtuned Posted February 5, 2010 Share Posted February 5, 2010 So bolting on of these Headers up to your OE cat is out of the questoin huh. Guess you need to buy an aftermarket larger CAT to connect to the header then you cat-back?? Link to comment Share on other sites More sharing options...
