I had Rip Rook install his 4" exhaust system on March 28th. All I can say is WOW!!! He did a great job on the install. All of the factory hanger locations were reused and all of the joints welded solid. He even painted all of the welds. The db meter says the truck is louder but to my ear I don't agree. I think that the lower tone from the exhaust is easier on my ears. I can have the window down and talk to someone outside without yelling.
The 5" stainless tip looks huge. Oo.
