you should check out Scott's Headers and Mufflers! its in beaumont, the number is (909) 845-3996. i just had him install a whole new system from my kooks headers all the way back. i have an 89 and my system has a magnaflow resonator with two 2.5in inlets and a single 3in outlet. the 3in goes around the gas tank with all mandrel bends and then it breaks back off in to two 2.5in pipes that go on both sides of the differential (so there isnt those ridiculous bends like the stock system has) in to two dyno max super turbos. IT SOUNDS FREAKIN AWESOME! it wasnt too cheap but for the work i got out of it, it was waaaayyyy worth it!
