... I don't hear it in the video posted above by the other guy who has the Borla.
Are you referring to the video from the interior of the car, or is there another one that I missed?

Yes, Yes, Yes, Depends and Yes. Ha ha
The Borla exhaust totally changes the character of the car. It's like a Mountain Lion next to a house cat. Sounds great at start up with deep throaty sound like I had with my Mustang GT. On take off it sounds great up to about 2500 rpm where I start having some issues with it. Start to feel reverbs in that area if I'm going slow. On fast starts its a beast and sounds amazing all the way through the rpm scales. Literally sounds like a high end race car and not a hot rod rice burner like some exhausts on the SHO do.
When cruising, if the engine is not working hard there is very little noise. If it is working against the wind or uphill then you get the dreaded droan depending on the rpms. You can get rid of it by manual downshifting.
I'm going back to the muffler shop today to see if they can do any tuning to it to get rid of the slow start 2500 rpm reverbs. It shakes the car sometimes and it doesn't sound right. I don't hear it in the video posted above by the other guy who has the Borla. If you listen to that video with a good quality stereo system you can hear the exhaust much better than just using computer speakers. There is a night and day difference. I don't hear the reverbs on his take off so this may be an individual thing and I'm not hearing any droan on his cruising speeds. I'll keep you posted in what I find out.
First impressions are these are some serious SHO changing pipes that sound amazing on fast starts or at idle. I'll keep you posted on the rest. If anyone has any ideas let me know.
Forgot to mention that I also have Unleashed Tuning Stage 3 Tune and Airaid CAI installed. Haven't broke into the 4s yet on my 0-60 times, but it definitely
squawks rubber going to second gear and jumps like a barrel horse.

both sound really good to me. Wish we knew if it's good for a few ponies and ft. lbs. or not.
I doubt it. Torrie at Unleashed Tuning didn't think we would see much in performance gains with any exhaust system. Most of the performance gain will be in the tuning.
I bought a universal x pipe, 2 pypes M80's, and a set of nice pypes tips...
I should have all my parts by thursday or friday, then Ill be getting to work on it. Cant wait to see how its gonna turn out.
