I've recently moved back to the east coast. About 6 months ago I purchased an 07 yukon denali on my father's recommendation. When I arrived last week he showed me all of the mods that he has done. I was amazed at the horsepower/torque gains!! His truck is a rocket. Personally I think it's plenty fast enough stock.. It's so powerful that when I floor it the truck feels like it's out of control. I'm afraid it's going to break the drivetrain. Amazing power. Anyway, He installed the gm cai, upgraded 15" brake package, corsa exhaust and ecu..
the exhaust is nice around town and only get's throaty when opened up. Mine is going in next week for everything! I can't wait. I drove his on the highway for a few miles and had averaged about 20mpg for at least 30 miles total. I'm truly impressed. I'd post a pic but from the exterior it looks stock besides that dual exhaust and the big rotors.. I'll see if I can take a snap of those tomorrow.
Happy New Year!
