Intake/Exhaust
Installed a 4" exhaust with an eliminator pipe, this air filter and the truck ran like it was really breathing for the first time! Awesome bang for the buck!

High flow top quality. Expanded metal inside and outside so there is no worry about collapsing and getting sucked into your turbo. Definitely will buy another.......
