GHL headers and Dual exhaust out???

[raacer]

Please offer any opinions about GHL headers and dual in and out exhaust for my 1990 C2. I use the car for street and track events.
Any noise level, performance or personal preferences or pictures of the system would be appreciated.

raacer,

I have the GHL header exhaust set up but I have the single out and not the dual out. I went this way because I didn't want to change my left side rear bumper. I'm also using the car for street and track. But I haven't tracked it yet because I'm still in the conversion stage.

Noise level - it's loud but I like it. It has litte resonance around 2-3K but from there it screams.

Performance - I didn't have a chance to have a before/after dyno but I can tell some change in bottom end torque from butt dyno.

Pictures - no pictures but search rennlist.com. I think user 'Christer' posted pictures or has them on his profile.

I went with the 4" tip which is bodering the rice look. I don't have the cats installed yet and that may quiet 'er down somewhat. I need to get a db read so I'll know if it's too loud for some local events. Other than that, I'm very happy with the system.
