yup.. the unit was already in the car when i bought it.. and all is good in there.. the clamps are definitely not over tightened cause there is no collapse in the air bridge.. there is just the right amount of play for the little bit of give needed for those joyous moments of WOT.. I've never heard of halltech, but then again my last toy was an SRT8.. this is my first Chevy since my '96 Camaro SS 16yrs ago.. i will say it sounds killer along with the exhaust the guy put on it.. and has hella power.. I've obviously never driven the car without those two mods so i have no basis for comparison but man is it a powerful car. and the sound turns heads everywhere..
thanks for the reply..
