Thanks. Always a work in progress.

How do you like your Borla exhaust? I have Magnaflow, but almost too throaty at highway speeds.

Makes sense, and you're right, more than enough power on almost SC setup, still too easy to break the rears free without much effort

Borla is great, I wanted quiet so I don't notice her at all all the way into excessive highway speeds - this is the touring version

Great looking rig. A similar question about the HP. The 6.2 in the Denali, mine's an 07 advertises 425 hp and similar torque numbers. Any idea what the real number is with your past experience? Some advertise higher than what it is and others lower than it is for EPA reasons. Got any feel for what it is at the crank or rear wheels? Does you Camaro have the 6.2? Thanks

Lots of variables in trying to calculate crank horsepower to rwhp. Automatic vs manual drive train is one of the main factors. Some would say a good back of the napkin guess is to pull 20% out from the crank to the wheel for an automatic, and 15% for manuals. So for an auto at 425 at the crank, it's making maybe 340ish at the rear wheels.

My Camaro is a 6.2, but it's highly modified. All forged lower end, balanced and mapped, ported and polished heads, cam, supercharger, bigger injectors, boost pump etc. So that 6.2 compared to my Yukon build are completely different animals.

Hope that answers the question.

That's clean, all performance mods aside I think the way you did the two tone paint is my favorite part.

Thanks, good question. It's just like the newer Camaros (and ZL1's), and "V" versions of Cadillac's hood heat extractors. It's cut in to the hood to allow air to flow up and through. This is a custom one off, that we took and modified from a version on my SEMA Cadillac.

Hey buddy do you have a part number for the extractor handy ?

It's a custom one off piece at the moment. I have the prototype installed. We will be making a few production level extractors this spring. My partners been waiting for me to send this one back for the mold to be made.

Ah ok, I thought you meant the hood as a whole was one off because of the extractor fabbed in. I got it, the extractor itself is one off.
On my search I saw a few different styles online that looked similar.
