| Exhaust and air system?
I bought an 04 duramax about four months ago. I am now settled in with my payment and am looking to start up grading on parts. The whole truck is stock no performace parts on it yet. I was going to to start with an intake and exhaust system. For these what would you all recommend I buy? I just dont know about things like are duals going to benefit me more or just hurt my wallet and what type of air intake to get. You help would be appericated. |
