Not sure which 2005 GMC Sierra Exhaust Headers & Manifolds are right for you? We have over 918 customer reviews, with an average rating of 4.5, to help you find exactly what you're looking for. Here's what some of our customers have said:
"I installed JBA short-tube headers on my '05 Sierra Denali. The fit was excellent but I have an exhaust leak on the driver's side at the flange. I used the gasket that JBA provided and have made sure the bolts are tight but I can't seem to stop the leak.
On another note, whoever packed the headers for shipment didn't protect the metal head gaskets. When I opened the box the metal gaskets were all bent up from banging against the headers in shipment." —Kynan B from Seguin, TX bought a JBA Cat4ward Headers for a 2005 GMC Sierra.
"2005 gmc Sierra sounds great with these headers and also it increase my MPG and more important to me was the horse power,great product even better price, Thanxs" —Juan E from Ventura, CA bought a JBA Cat4ward Headers for a 2005 GMC Sierra.
"They took a little over a week to get here, they were exactly as pictured. It took about an hour and a half to install them including the time to remove the 3 bolts that broken off in the heads.(matco tools makes a great stud puller) We didnt even have to jack the truck up since I'm running a taller tire and have the bars turn up in the front for plowing. They look great and sound good, the idle has gotten a lot smoother and the truck shifts much smoother. Noticed a power gain especially with a trailer on it. They are a good addition to the intake, tb spacer, and tuner I already had. I would recommend spraying all bolts with plaster first." —Mark W from Berea, OH bought a JBA Cat4ward Headers for a 2005 GMC Sierra.
"very happy with the JBA headers, they were easy to install, they're good looking and i guess it's because of the thickness of the tubing, they don't make that common header noise. some guys like that ticky noise, and on some stuff i also do, but in this application, i'm glad they're quiet. i already had a flowmaster catback force 2 3 in. single exit system on the truck, 05 gmc sierra 4x4 5.3, and was concerned about the headers making it louder, but if anything they made a little quiter and smoother running, seems to be better on gas and looses less mph on hills. overall i'm very happy with the jba headers !" —Jeffrey B from Oxford, NC bought a JBA Cat4ward Headers for a 2005 GMC Sierra.
