Looking to order a muffler...I currently have a 3" in & 3" out Spin Tech, but had to use my stock exhaust piping which I think is actually a little smaller.

Anyone...?

2-7/8"
I got the 4in system fabbed up for the truck, should get it on by sat&#33; Very anxious to hear it....I put it up under there and cranked it, seemed really nice and throaty but I could hear the headers where things werent closed up tight&#33;
