hey i was wondering if anyone could help me out. i have a 1994 Si coupe. d16z6 vtec, when i bought the car it came with a DC sports 4-1 one piece header connected to a 5zigen catback exhaust system, i hit a big rock today on the road and put two huge dents into the bottom of the header on two of the pipes. i dont want to spend 400 bucks for a dc header , im tight on cash and need a quick replacement. if i get an ebay 4-1 will i have fitment issues bolting up to my aftermarket exhaust system. or should it all be standard fitment..? any input highly appreciated. Thanks!

 

You shouldn't have any fitment issues since the header is bolting up to the catalytic converter (if your car is equipped with one).

Basically, it should be a direct bolt on without modifications.

 

Okay cool thanks, and one more question... what is a better design 4-2-1 or 4-1 for a single cam vtec. what are the differences anyhow?
