GM's 4th Generation pickup was built on the GMT400 platform and available with multiple versions of the ubiquitous small-block V8. From 1990-94, GM offered a cult legend, the 454 SS. Whether you needed to haul a trailer, get off the grid, or rip down the 1320, GM had a C/K1500 for you. But if you want to bring that OBS into the 21st century, Holley has all of the parts to make dropping in a Gen III/IV LS engine a bolt-in affair!

Holley is home to some of the top-performance exhaust brands in the world. Brands like Flowmaster, Hooker BlackHeart, Hooker Classic, Flowtech, APR, Dinan, and Flowmonster combine to cover thousands of applications and a variety of budgets. Whether you are putting a full stainless steel exhaust on your late-model muscle car or if your rat rod needs a set of Lakester headers, Holley’s exhaust brands have you covered.
