About Pypes Performance Exhaust

One of the principal ways of getting a lot of bang for your performance buck is to replace your car’s compression-bent exhaust system with a mandrel bent system.  The simple fact is that a mandrel bent exhaust system will flow twice as efficiently as a compression-bent system and we all know that efficient flow is one of the main ingredients of power.

Pypes Performance Exhaust supplies complete mandrel bent, performance exhaust systems for American performance vehicles ranging from the 1950’s to the present day.  We also offer both gas and diesel truck systems for the most popular American Pick-Up Trucks!

Our systems and accessories are fabricated using stainless steel materials that will provide their owners with long term service and satisfaction……and, Pypes products are backed by our limited lifetime warranty!  Most of our systems include a custom designed X-Pipe at a considerably lower price than others that include no crossover at all or just a basic balance tube with their systems.  A typical Pypes’ “complete system” will include an X-Pipe, a pair of mufflers, a set of tailpipes and all of the clamps and hangers required to install the system.

Pypes also performance matches systems with a choice of their own distinct mufflers to best suit your horsepower and sound requirements, rather than forcing you to buy one type of technology that may not be best for your application.
