Yeah I am doing the whole exhaust including headers

 

3" is a lil much for a 4.3L. they have plenty of torque with 2.25". but to each their own, ive got 2.5" on mine with no cat and a glasspac and it rips it pretty good when im on it.....but its just a wheeler so no cat is ok...... should sound pretty badass with 3" and a 40 series though!!!

 

Yeah I want to put a super 44 in the set up
