which one
 

Trying to decide between a Hp racing and a Greddy Evo exhaust for the civic.. which one? and why?

Apexi N1 catback... why because it sound Pissed and very deep on my b18c1 when the higher rpms but queit when just going around town...

I coudn't tell you which one to pick out of your 2 never heard either...

If you get a chance..post some pics up as well. I know the GReddy Evo get's a little loud from what I've heard after a little while. I had a GReddy SP on my Del Sol and i fucking loved it. I would definately go GReddy Route again. I don't have much expieriece with HP racing, but I've heard lossa GReddy's...And i like them..therefore..my vote goes GReddy.

Thermal or HKS Hi-Power. Friend has Hi-Power on his b16 4-door and it sounds mean as shit. So deep. Plus I had HKS on my s13 and it sounded awesome.

between those 2, my choice is GReddy Evo. But I still rather have Thermal R&D.
