Is there a 3rd party company that ranks exhaust. Kind of like a Motor Trend giving their top 5 or 10 cars of the year? Except in this case they rank exhaust? I know its a long shot, but doesn't hurt to ask.

Thats a good idea. I really don't think there is a company that does that? You will find most will be recommending: Borla, Corsa, Bassani

I know this doesn't address your question, but if your in the market for exhaust check out http://www.granatellimotorsports.com

I had these on my 04' and all I can say is you will not be disappointed. The look, sound, and price, will blow you away.
This system did not require an x-pipe to rid the burble and popping sound. Nor, did it sound like a motorboat at idle.
There is a video showing installation and sound clip - don't be misled on price compared to Borla, Corsa, Magnaflow, and GHL!
This system was $500.00 delivered to my door! I paid an additional $100.00 to have them installed and tack welded into place.

Thanks for the post Chris, I actually had already ordered the SLP Powerflo's, I was just wanting to see where they rated against other exhaust systems? So I take it there is no 3rd party consumer reports out there?

Chris,

thanks for the post. That system sounds wonderful. Civilized but nasty...just what I am looking for...now to save up the George Washingtons...:)
