The MagnaFlow Street Series 15750 is a stainless steel cat-back exhaust for 1996–1998 GM full-size pickups with the 5.7L V8. It is made of durable stainless steel and built using CNC precision robotic manufacturing techniques, all backed by MagnaFlow's limited lifetime warranty. Extensive dyno testing is used to ensure that this cat-back exhaust system increases engine power and performance by improving the flow dynamics and evacuation of exhaust gases. Against a stock system or a cheaper universal kit, the appeal is a direct-fit pipe layout with a straight-through muffler and polished 3.5-inch tips. The manufacturer says the extensive use of 3D scanning during development is meant to deliver OEM-like fitment.
Fitment is the main thing to verify before ordering. The manufacturer's install sheet describes this system for the 1996-1998 GM full-size trucks, short bed, V8 5.7L, Ext. cab.

The manufacturer's install sheet for this system starts with removing the stock exhaust, so plan on disconnecting the factory pipes and hangers before fitting the new piping. The manufacturer recommends professional installation, and it warns that aftermarket trailer hitches, larger spare wheel and tire setups, or ride-height changes may require modifying the exhaust for proper fit. Allow the existing exhaust to cool before working underneath, and confirm your truck matches the listed application before you start.
