right now i have Edelbrock 1 5/8 headers and Y-pipe flowing back to a stock gutted Cat and stock muffler and tail pipes, are edelbrock headers anygood? i have been told they are junk, also should i leave my gutted Cat? and what is the best cat-back? i wuz going to keep the edelbrock headers and my gutted Cat, and get a Flowmaster Cat-back w/ dual 3" outlets, what do ya think??? your suggestions are apprieciated

 

If you're looking to squeeze out every last HP, then yes Edelbrock is a little restrictive, but there's no need to waste money and get a new set. I wouldn't recommend the flowmaster cat-back, it's among the most restrictive. I got the Hooker and am very satisfied, haven't heard anyone that isn't. Plus it flows better, to me sounds better and comes with dual tips.

 

As in your other post, SLP's and Flowmaster if u want sound, not sure about the Aerochambers flow compared to Flowmaster since I've never seen any comparison.

 

I have Hooker Shortie headers and Flowmaster cat back.I knocked off 4 tenths in the 1/4 mile with that.I am satisfied with my set up.
