Just got mine installed and I'd have to say it's pretty loud while cruising. They told me I got the most recent design. If your not accelerating AT ALL, it's good, but just a hint of throttle and it starts to get loud. I'm hoping it'll mellow out as it breaks in... and I didn't get one of the original units.
Daniel and Antonio's dad were really cool guys. The wrapped the old exhaust up in plastic wrap for me and stuck it in the trunk.
The Bastuck is still for sale if anyone's interested, but I may wait for this unit to break in first.
Let me get this straight... You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
