I just got DC headers....And i was wondering if i need anything else or can i just bolt right up to the stock exhaust system? Also does it fit to the stock?..Willl this hurt me or will i gain by just putting the headers on?...

 

Replacing your gasket would be a good idea. And yes it should bolt right up to your exhaust. YOu'll get a small gain, an exhaust and intake would see greater improvement.

 

it'll be hard to notice much difference without other minor mods. stock honda exhaust manifolds are quite good and the biggest thing a header helps with is weight.

 

Hmmm.... so the stock cat has a 2.25" inlet?
