when i bought my car it came with flomaster cat back exhaust with a single 3inch outlet i want to get edelbrock tes header should i get the edelbrock cat back system with dual 2 1/2 inc outlets or just stay with the flowmaster ??

I'd recommend the Hooker cat-back. To me sounds better than flowmaster, and it's cheaper than the Edelbrock I believe. I bought the $200 cat-back and had it welded on. Also comes with the tips as well. The muffler with the cat-back, flows better than a flowmaster.

I'd say leave it and save the $$, unless you'd like a change in sound or its worn out.

Stay with Flowmaster, just change the muffler if u want dual outlets.
