1980 Fiat X1/9 with a stepper header and exhaust system from Allison's Automotive. The system features a Hushpower muffler and weighs 18 lbs with a catalytic converter compared to 36 lbs for a stock system. This header fits cars with a/c. Information is available at www.allisonsautomotive.com
So I have heard it in person and I was right. Sounds amazing. Not only that, this cars power band has completely changed. This thing pulls all the way to 6500 RPM. It used to stop at about 4500 and now it is just a fire cracker. I am not a header fan at all but what this did to this car was amazing. Dyno sheets show a TWENTY PERCENT boost in HP. Worth every cent.
