I've been eyeing a new and different look for the GTO tips, but something that looks like it should have com with the car from the factory.

I like the exhaust that are on some of my favorite supercars:

I selected the "D" shaped tips for 2 "form-follows-function" reasons:

1. According to a friend of mine at the local USAF base, he said that D-shaped ports (most famous one is the F-16's port) have low turbulence.

2. The bottom of the D-shaped tip is perfectly flushed with the line of the rear valience which greatly miminizes the tips from scaping steep driveways and parking lots.

Looks good. The right one looks like it sticks out a little bit futher than the left. It may just be the camera angle.

it's missing the rubber hanger which I just got yesterday afternoon from a dealer special order.....
