I think it is time to put duel exhaust on the good old blazer. So since I have 2 weeks off from work I think I will build it my self. I will buy another dynomax cat with another Flowmaster super 40 muffler. I will by a x pipe to balance the system. I want the tail pipes to run right out the back. The only problems I see I will have is around the gas tank area. The T-case will be easy to do I will use clamps on both mufflers maby cats. The rest I will weld. The system that is on my truck now I did all my self. So I kinda know what I am doing . I am after some ideas and tips from you guys that have built there own system.
