Hey guys-

I am currently working on my turbo setup for my 2000 civic si. I am considering two exhausts for the setup, the HKS Dragger Exhaust and the Thermal R&D turbo exhaust. The specs on the HKS exhaust say that the piping is 95mm(about 3.7 inches) and the opening is 130mm(5 inches). I was wondering if this is overkill for my setup because i don't plan on ever running above 10 psi. My friend has a thermal R&D for his setup which is similar to mine and it seems to be working out ok, but i was just wondering if anyone knew how well the dragger exhaust works for the turbo.

 

the piping on that exhaust is 60mm for civics and integras...an exhaust with that piping size is the apex-i GT Spec exhaust. both companies make good quality products though so u can really go wrong.

 

Thanks a lot. I am gonna look into the GT Spec exhaust for the setup. I dunno if 95mm will be too much, even though its only .7 an inch bigger than the Thermal R&D.
