Cat-Back Stainless Exhaust System for E30 325i

Performance part. Our cat-back free flow exhaust system fits the BMW E30 325i including the 325ix. It's constructed of 100% polished 304 stainless steel. This system saves over 10 pounds from the stock system. There is a performance gain, but we don't quote horsepower because most vendors are exaggerating gains. The note is slightly-louder than stock with a nice throaty sound when you step on the gas and no harmonics at cruising speed. These are a "bolt on" direct replacement for your factory system using all the factory hangers - yes, you can do this yourself. Note: This system can be used on the "e" model, but you will need to fabricate a Y connection (because the "e" center section has a single pipe and the "i" has dual pipes). Includes flange bolts, rubber mounting donut, and donut flanges.
