2.5" vs 3" exhaust

Deadman · 06-23-2011, 06:04 AM

Basically deciding on what cb to buy at the moment. I saw aam I believe is 3" as well as Gtm. My decisions are between berk and invidia currently unless swayed another direction .

Stick to the 2.5" system if you are staying N/A.

Even with Forced induction 2.5" true dual will be enough. However, track vehicles will prefer 3" single all the way back.
