"I bought these to replace the cast iron manifolds. Everything bolted up to the existing locations with no modifications required to the exhaust system. The installation took a while, but it wasn't difficult. It would have gone faster with two people. The paint came off on the first drive, even though I tried curing it using the heat from the exhaust gas. I bought a can of high-heat paint and repainted them. had to remove them to do that, though. It would have been nice if they came painted with high-heat paint. As is typical with headers, the bolts don't stay tight. I drilled holes in the bolts and safety wired them in pairs. Don't even bother with the included gaskets. Buy a set of steel reinforced ones as the paper ones blow out fairly easily. The performance increase was dramatic. The engine was responsive to the throttle anyway, but the headers improved on that quite a bit. Gas mileage increased about 1 mpg as well. Used to average 13.5 mpg, now it's 14.6 mpg. With these headers feeding flow master mufflers, it sounds like a truck should sound - meaty and powerful." posted by: 96GMCTruck on September 8, 2011

"I put the headers on my 93 GMC Sierra with a 350. ZZ4 block bored .030 over and Edelbrock Multi-ponit fuel injection system and a strong cam. Roller setup. Aluminum E-tec heads and these headers. Sounds great. Lots of powers. and looks good. Buying the coated shortys would be good for an engine with this much power. 500+ RWHP" posted by: MetalMikeJr on January 20, 2010 view all 2 reviews
