I am still debating on what I want to do with my exhaust. I drive the car in my sig, 01 Blazer, 5-speed, with a 4.3L vortech engine. What do you think would be the best exhaust setup that would provide me with both great sound and performance? I am thinking I want to go with dual 4-chamber exhaust right now but not sure what kind of exhaust to use, I don't want to use flowmasters. What would you guys suggest?
