Description
2001-2004 Chevrolet / GMC Cold Side Tube Factory Style HSP DieselThe LB7 Duramax has a very restricted charge air system from the factory. After realizing the potential power loss from the small diameter factory tubes, we increased the size of the tubing to 3'' which proved major power gains over the factory intercooler system. While dyno testing the HSP upgraded intercooler tubing, we saw incredible horsepower and torque gains from such an over looked component. Power increases will fluctuate between models due to

Inseam is way off.
Color: Burgundy, Size: 38W x 30L
They are nice, the waist is the right size, but the length is more for an orangutan. I’ll be lopping off 5 inches easy, not even close to a 30” inseam.
Inseam inseam inseam.

Too Much Back, Ain’t Enough Slack
Color: Brown, Size: 36W x 30L
Sadly the color doesn’t quite match the photo—it looks cheaper IRL. However, the form of the pants are cool, but they don’t fit me.
TLDR: These pants aren’t for guys with back. Good looking style though.
