Gibson 88-89 GMC C3500 Sierra 7.4L 3in Cat-Back Single Exhaust - Stainless

This Gibson cat-back exhaust system is built with 3-inch diameter, mandrel-bent stainless steel tubing. Mandrel bending ensures the tubing maintains its diameter throughout the bend, which helps the exhaust gases flow more freely than with crush bends. This improved flow is key to unlocking better performance from your 7.4L engine, especially when you need extra power for towing or climbing hills.

Designed for a hassle-free, bolt-on installation, this system uses factory-style hangers and includes all necessary hardware. The Superflow™ muffler is baffled and chambered, tuned to give you an aggressive exhaust note without excessive interior drone. You'll notice improved acceleration and passing power, with dyno tests showing gains of up to 32 horsepower and 60 ft-lbs of torque. The system exits behind the rear tire with a polished stainless steel slash-cut tip, giving your truck a clean, professional look.

This exhaust is constructed from durable stainless steel, which resists corrosion and is built to last. It's a solid option if you're looking to get more performance and a better sound from your C3500 or K3500 truck.
