If you followed our 1985 Chevy K10 “Big Green” project truck series, you already know that we engine swapped the old and tired 305 cu-in V8 for a brand new Chevy Performance ZZ6 350 cu-in V8 crate engine. That was a giant step for the project. Big thanks to Ted Ax at the Ax and Allies shop for the help! The new engine is rated at 405 hp and 406 lb-ft of torque. However, we did not have a proper exhaust system on the truck until now.
The folks at MagnaFlow sent us an exhaust kit that includes all the components and tubing for us to build a proper dual-exhaust system. The old restrictive single-outlet exhaust system had leaks and made the truck obnoxiously loud.
We went to our friend Devon at Devon’s Car Care in Boulder, CO for his expertise with trucks and building custom exhaust systems.
The result was very satisfying. The truck purrs gently at idle, but roars with V8 authority near wide-open throttle.
Watch this amazingly quick and successful custom exhaust build.
