i got a 2001 camaro ss, stock exhaust. i'm not sure whether to order a 2 1/2" or 3" cut out. i got under the car today and measured the circumference and did a simple calculation and discovered that the pipe has a 2.7" diameter. RIGHT IN BETWEEN 2 1/2" and 3"!!! any help would be appreciated.

Most ppl get a 3". You also have to remember that the ID of the cutout is going to be less than 3" as well.

ground clearance might be an issue make sure you remind the welder of that

I have a 3" QTP cutout, no problems with ground clearance.
