I have a set of these in the 2.25 diameter and I love everything about them. Installation was a breeze and the fit and finish is fantastic ! Great job Joe !!!

They are not. We are working on a new site right now. You can give us a call at 989-476-0135 for more information or to order!
They can built just about anything you can imagine. They build single S300 and S400 kits along with multiple twin and triple turbo configurations.
Wanna sponsor me a set? I didnt see any gains with the others, kinda hard to justify the cost..
Brian, Shane is correct. We are not in a position to sponsor a lot of trucks at this point. We have done back-to-back dyno testing comparing a truck with the BD driver side manifold and stock everything else to our full billet setup. I'll post a few of the graphs. We'll have more results from engine dyno testing soon on both the 2" and 2-1/4" setups.
Thanks Dave! We do offer the larger 2-1/4" setup for the sled pullers and higher horsepower setups. We can port match these to the new Brodix/Wagler heads as well.
Here are a few of the 2" and 2-1/4" side by side!
2" Complete setup!
is that a ceramic heat coating on them or just exhaust paint? if anyone thats running these wouldnt mind posting installed pics that would be great :thumb:. the engineering/craftsmanship that went in to these and other HSP products ive seen is great!
It is a high temp Ceramic coating. The new black coating they are now using is rated to 2000 plus degrees and holds up really well!
Here is the test setup!
Here is the test setup!
I vote for both. Ceramic coat, then heat wrap 'em. :thumb:

Wrap it blankets like these will help with under hood temps and keeping the thermal energy there for the turbos too.
