High quality, exceptional design and performance define our crossover product line. They are a proven winner when it comes to bumping up the horsepower of your daily driver or race car. Our Driveshaft Tunnel X crossovers fit a variety of classic cars that are prone to limited ground clearance. There's no skimping on materials here.
All crossovers are constructed of 409 stainless and include dual 409 stainless reinforcement plates at the welds where they are needed most. All pipes are mandrel bent, to allow for the maximum flow of exhaust gasses, which boosts acceleration. The Stainless material resists corrosion and extends the life of your X-pipe.
This semi-universal crossover is designed to let the rear legs of the crossover run in the driveshaft tunnel for extra ground clearance. Modification of body pan is required on 67-69 F-body convertibles but can be done! We recommend using Part Number RPE631FA.
Features:
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.
