Pypes Exhaust Systems are designed to deliver enhanced performance, provide extra punch in the passing lane and improve gas mileage. Fabricated using the highest quality materials, our smooth, seam-coated, 16 gauge, mandrel-bent, stainless steel pipe ensures maximum exhaust gas flow, which can significantly boost horsepower. The stainless construction of our pipes and mufflers enables them to resist corrosion and extends the life of the system. Our mufflers are precision matched to deliver the ultimate in sound and performance. Pypes systems come complete with a pair of precision matched Pypes mufflers, correct tailpipes, cad plated clamps and hangers. These systems can be installed at home without any special tools.* Our Special X Crossover allows the rear pipe legs to run in the driveshaft tunnel in order to optimize ground clearance.

As we were restoring our 68 RR we knew that the exhaust had to get done. My father wanted to do traditional straight back but I wanted something more! Searching exhaust systems I noticed one thing, if you wanted stainless you were going to be spending a fortune. That is until I found Pypes Exhaust. Price was affordable and it went together very well. Just had to do a little tweaking on the pipes to match our headers. Now we have a very professional looking product that we did ourselves in the garage. Hoping to share my pictures in the gallery here.
