Hi Brad, will all due respect to the resources and nrg you guys have put into designing what appears to be the ultimate product, there are some other packages that makes it worthwhile to go with. I got myself the NHP Motorsport exhaust system and in all honesty, there is no drone (as advertised). Okay perhaps quieter than the other aftermarket basement-made exhausts, for 2k it gave my car an incredible weight reduction, some minor HP gains, GT style tailpipes, plug & play installation (2hrs) etc.... that beast starts to reveals itself past the 4k rpm and sounds like a beauty in the upper rpms. I personally give it a 9.9 on 10.
Just not as cheap as some others but check it out!
