I currently have a DC header(i know its a POS) with carsound cat and a apexi world sport.

I wanted to ask you guys if vtec would be louder than SH%t when it engages cuz my sounds like its unleashing like crazy. But it dissipates when it gets into the higher RPM's. Is this normal?

I am planning on getting the prospeed header once i get the funds.
I just wanted to ask everybody from experience with any header on these H22's.

thanks

 

check out the gasket if it's the wrong size it will give you an exhaust leak.
