Exhaust Set, Pypes, 1978-88 G-Body, 2.5" Catalytic Converter Back, Rear Exit

Stainless steel construction

Mandrel bent piping

These all-inclusive kits from Pypes Exhaust have been designed specifically for street machines and muscle cars. From the 16-gauge mandrel bent stainless tubing to the TIG-welded stainless steel mufflers, these kits are designed to last for years and provide the smooth sound you desire. Each 2-1/2" exhaust system mounts to your existing 4-bolt flange catalytic converter and are available with four different muffler choices or without mufflers. Hardware and instructions are included.

Four mufflers to choose from, in order of quietest to loudest;

Turbo Pro; features flow control channels that eliminate drone, resonance, and flow turbulence while maintaining a steady flow of exhaust gasses that mimics the CFM of a straight pipe. Expect a quiet mellow tone with a true performance sound.

Race Pro; provides the greatest flow out of any muffler in the Pypes line. The Race Pro features a straight through design wrapped with packing to give you a great sound with minimal airflow resistance. The sound is calm at idle and low RPM cruising, but open the throttle and the sound is unleashed!

Street Pro; a great street/strip muffler that will maintain its rich sound qualities for the life of the muffler. The chambered type Street Pro muffler is recommended for stock to medium modified vehicles looking for an aggressive, but not too noticeable sound.

Violator; provides the most aggressive sound out of any muffler in the Pypes line. It features a 3" internal louvered tube with small sound deflector chambers to achieve the aggressive sound. The sound at idle is unique, but once the throttle is opened, the exhaust becomes incredibly loud and noticeable.
