quite headers
 

I had exhust manifolds running into an aftermarket duel exhust kit. Today I added FlowTech headers and an H-pipe into the same aftermarket duel exhust but the car wispers compared to before. Is this normal, is it because the H-pipe, or do my headers suck?:confused:

H pipe
 

I believe that the H pipe definitely makes it quieter. Helps performance too. If anything, tubular headers are louder than exhaust manifolds.
