Just buy the AE exhaust and call it good. I'll even take a video showing how loud and pleasant it is with AR catless, intake, and FMIC. Those combined have made the AE exhaust even louder and at WOT there is nothing that sounds as sexy.
Sorry, my inline 6 will not sound like a fart can. The guy with CPE and the HPF Gen2 sounds OK, but it still sounds too loud and way to raspy.
Here's a newer vid from AE.
