Cant beat it!

Worth the money! Sounds great and looks great. Had a few dings/dents in it when I received it but tapped them out. Only thing I recommend is buying a "V" band clamp with it.
5" Exhaust

I have the exhaust for a little over a year and have 2 broken hangers, which have also created holes in the exhaust. However, the exhaust has a great sound when I first got it but I am now in the market for another exhaust due to the hangers.
Not satisfied!

I've had this exhaust on for about a year and a half, in that time there's already two broken exhaust hangers out of three! I wish it would have remained steady because when I put this exhaust on I thought it sounded awesome! I personally would save your money for a more sturdy exaust.
Absolutely worth it

Installed on a 2004.5 Ram 2500 SC/LB If you're looking for a cheap 5" exhaust, this is the way to go. Even though it's cheap, it fits together seamlessly, I would even go as far as to say it is the best exhaust on the market. As far as installation goes, it only took me one hour to take my 4" silverline off and put this on. The band style clamps that this exhaust use from my first experience with them, are far superior and easier to use than the saddle style clamps. But anyways, the instructions it comes with are very helpful, right down to what torque the bands need to go to. You WILL NOT BE DISAPPOINTED WITH THIS EXHAUST!
