Who said size doesn't matter? This huge 7" diameter tip is the perfect addition to your 4" exhaust system and gives your diesel the most aggressive stance. 409 stainless steel 16-gauge bolt-on high-temp black powder-coated exhaust tip is design to fit the popular 4" exhaust systems. Special high-temp black powder-coating is heat resistant up to 1600 degrees F. Stainless steel band clamp which is tack-welded over a 4-slotted inlet ensures a very secure grip. Finally, this exhaust tip features a stainless steel laser-cut logo plate that stands out against the black tip for an aggressive style. With a 4" inlet, a massive 7" outlet and a 18" length, this single-walled, rolled edge,15 degree angle cut tip is a nice compliment any 5" exhaust systems.
If you are looking for a tip that will give your truck the wow factor this is it. I put this on my 2005 cummins and it sounds a little louder but looks a lot better. all my friends say " damn that is a huge tip".
this think is awesome.
