Thank you VERY much for that informative reply. I actually do want to keep my new car's setup on the downlow as far as sound is concerned. So Ill be looking into that exhaust you had mentioned.. although I most likely will be picking up the Comtech I/H in the very near future.
For me personally the GSR is fast enough to suit any of my needs.. but it will be nice to know that Ill have a jump on any other joe that may have a stock GSR putting around town ...
Again thank you for you reply!
