I can now afford to purchase a GMPP Sport/Performance cat-back.

I have some questions:
- How many decibels is it at WOT? (Some auto-x events require 90dB or less)
- Is there any performance difference between the Performance and Touring?
- How would you rate the loudness of each exhaust, for those who have heard each in person?

There is no performance difference as for the other two questions,there is a video in a thread comparing the two

Basically what I am trying to get at is can I pass the 90 dB limit with the performance GMPP cat-back?

I was actually looking to possibly buy from crateeningedepot if I could get a deal! Could you beat the GM employee discount price if there is a group buy, cause I can get the employee discount? (Or at least match it with free shipping?)

I would be interested as well. How about a shipping deal to Canada!?
