thanks everyone, it was a cool morning on the small exhaust runs and it was hot muggy mid day on the 4" runs. i will find out soon enough how it does once i make it to the track. so far 13.87 is my best time. its doing something cause it lean the wot afr out by almost a point.

sounded like it revved through gears quicker with old exhaust, very good sound, im gona have my brother turbo his tahoe,

dats tight!

new exhaust sounds good. sick tahoe!
