I have read on a few forums that this is a really good header performance wise but since it comes with a test pipe when you install it, you will have no cat which creates a bad smell.
But I'm just wondering, if you buy a high flow cat and take it to a exhaust shop to get it welded to the header, will it get rid of the bad smell that everyone complains about? your opinions would be a big help which I am considering on buying these headers but want a few pointers before I do. Thanks for your time!
