Well, depending on the truck will depend on what a stack this size will do. On 90% of the diesel trucks, It's not gonna help with H.P. gains. It can help lower EGT's. Mostly, it will give the truck a different "tone". Each stack diameter, and cut have a little bit of sound difference.

We do have some stacks NOW IN STOCK! I'm waiting for the pictures from the chrome department so I can show these bad boy's off. As for prices you will need to contact a Grand Rock Dealer. We have a few here on the site, so look em up & help support Diesel Bombers!

Thanks! I wish the warehouse was a little bigger personally....so I can keep more stuff on hand... but you know how that goes. I'm the peeon, not the pee-r....LOL Miter cut stacks are by far our #1 seller, but these 6" Aussies are catchin' up! I hope to see the same interest in the 7" Aussies as well!
