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.

 

Wondering if these stacks are available to buy yet and if so any idea on pricing?

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!
