Any one have a 4" or bigger exhaust for a 06-07 duramax lbz

This is the place for LBZ stuff http://www.kennedydiesel.com/

I run a 4" straight pipe setup on my LBZ. Picked it up from alligatorperformance.com for ~$240 shipped. Call them for better pricing then their website.

Get ahold of James @ Rollin smoke diesel , he has all the goodies you need at great prices and free shipping .

I will throw a second plug in for Alligator Performance. They are great to work with and a have very well designed website, with a large selection.

The bigger the exhaust, the louder and more drone many experience.
Some find it cool at first but it will get old, especially on longer drives.

Check out Diamond Eye's Quite Tone down pipe to reduce drone.

Yes bigger is not always better you will make more noise thats about it unless you have big power .

Im looking for somthing maybe someone has pulled off there truck and up graded to a bigger exhaust, that way i can cut it up to make it fit my H2. And i want it loader, it is not my every day driver so it will be ok. i just want it to sound like an animal rolling down the road.
