"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

"Easy to install and fit perfectly. Look nice installed except that the paint is easily scratched." posted by: Tomcat on February 13, 2009

"1995 Silverado Extended Cab 4X4 with 350 CI and T.B.I Carb. Installation was fairly easy. Had a little problem widening the Y pipe to fit the Header Flanges. Did not have to cut the Alt. Bracket as was suggested in Instructions, was able to slightly bend the second bolt hole portion of the Bracket outward and of the way of the #1 Exhaust Cylender Pipe resulting in saving it, but still only able to use one Alt. Bracket Mount Bolt instead of the two. The single Bolt holding the Bracket at this point does not pose to be a problem. Headers look good but wish I had opted for a better Protective Coating. The Coating supplied with these Headers didn't take long to burn off. Getting an average of about two more M.P.G. The performance increase is a little less than expected but still noticable, especially during W.O.T. Was shipped with the wrong set of Headers to Head Gaskets but were of good quality and Cust. Service was outstanding in providing me with a Rebate to purchase locally. A pretty good set of Headers for the $$$." posted by: Damyankee on August 27, 2008 view all 3 reviews
