And also I'm pretty sure the car feels faster throughout the entire rpm range, but is most noticeable at higher speeds, 4 & 5th gear, 80 plus ish. I guess it takes a while for the car's ECU to adjust, but I'm positive I can feel a difference. Keep in mind this muffler weighs 20lbs less than the stock one.

The tone is also sounding better as it breaks in, tighter at lower rpms, and more growlyish at higher rpms. I'm 100% pleased with it. Add all of this to the fact that the Borla is the least expensive bolt-on system there is for this car. Thanks again Bob. Borla FTW!!

Excellent post.

Very interested in this as well... The Borla exhaust on my former 350Z sounded great minus a considerable rattle at 3k RPM. It was enough to where passengers noticed it too.

Can't get enough info on which exhaust to buy... touring or sport application. I am looking for something that is more aggressive than the stock exhaust, but not so loud that when my wife finds out, I will be sleeping on the couch... I am also not sure which to buy... Dinan or Borla...I own a 2008 DCT M3 Sedan...Help please....
