Gibson GP115S Performance Headers, Stainless Steel, 1 5/8 Inch 14 Gauge Tubing

probly the easiest headers i have ever installed on a truck still not a easy job though and the sound and extra performance is awesome

when it comes to headers - you get what you pay for. Great quality, look great, and fit near perfectly. they came with every gasket and fastener needed. i would buy these again in a heartbeat. And i love TPC.

i installed this on my 5.3 00 silverado and as everyone else says you can feel the differince more in the low to mid range than any thing. very good quality also.

Install them on my 2001 silverado 4x4, 5.3 engine. Great product, removed my pacesetter headers which blow out after three years. got a pair of these and love them, big difference from the start. Took about four hours with taking off the old ones. big gain in horse power. I give them a 5++ stars. And this co. is very easy to deal with.

I have owned this product and wanted to let everybody know that by just adding these headers, its not going to make your exhaust sound any different. You gain about 5-20 hp and can notice the difference throughout the RPM range.

Very good qaulity and it's worth buying it, but I had a problem with A/C evaporator clearance, which is driving me nuts. The shield hits the headers and it makes a rattling sound. I think I have to bend the evaporator shield a bit to stop it. But over all very good workmanship combined with Gibson dual outlet makes a very nice deep tone sound. I like it..
