im now running a dc sport header on my zc engine with no cat (should have 1 put in some time next week) with no resignator, and its making a horrible tin can sound and is really rattly how exactly do i fix this and get back my deep sound without having to go back to a stock header? or will putting the cat back in the setup quiet it down alot?

 

the cat should quiet it down alot, just give it a try and if not good enough add a resonator.

The cat will definately dampen the buzz.

 

my exhaust was raspy as hell with no resonator and it still had a cat.

 

we'll see ill post up the results once i take it to the exhaust shop, im also thinking of doing an angled muffler instead of the magnaflow that i currently have for decreased resistance but ive got to check out my prices first. im thrifty dont want to spend too much
