i bought a DC sport header off my buddy who has an integra with an LS, i have a GSR, i no it bolts up to the head but when i tried to line it up wit the cat it wouldnt......the cat is angled one way and the header is angled the other way, is there anyway of turning the cat so it will match up? thanks alot

 

take it to a muffler shop and have them modify the flanges

 

that is a good idea but is there anyway that i can turn the cat or do anything else? b/c right now im runnin open header and that is loud as hell, im just trying to figure something out until i can take it there, b/c eventually i want to buy a test pipe

 

it shouldnt cost more than a few bucks to have it fixed
