Review on Enhance Your Mustang's Performance with Flowmaster 15820 87-93 Ford Mustang LX 3 In. T-Pipes by David West

I've been a long time Flowmaster fan but this one really let me down. If you think you can do it in a few hours, guess again. I'm a mechanic and have access to all the necessary equipment, but it was still brutal. When I started I wasn't even sure I had the right parts! I called Flowmaster for help as there were no instructions included and was told that some "adjustments" would likely be needed to make everything fit. They then told me that if anything was cut or altered, the warranty would automatically be voided. A bit like a catch 22, right? Anyway, it wasn't, and nothing even came close to it. If you get one part right, it messes up something else. As the last reviewer said, lots of cutting and shearing and lots of welding. It's all in the car now, but it wasn't much fun. And whoever the designer was that decided to put a big, ugly weld on the stainless tips instead of driving them was a real genius. Not impressed.
