After struggling for weeks tinkering with my exhaust trying to produce a no drone deep true V6 sound I finally hit the mark.
Stage 1: F-Sport Axle Back (By itself = too much drone, too high pitched for the cabin of a luxury car DD)
Stage 2: Removed secondary cats - Replaced them with Vibrant 12" Bottle Resonators (More flow and more of a rifling V6 sound but still a lot of drone between 2500-3000)
Stage 3: Game changer - Replaced the single stock muffler resonator with a straight through 14" long 6" across Magnaflow muffler (3 mufflers in total you say? YES!)
The result is the way luxury sport sedan should sound. If you have a girlfriend, wife, kids or are just over the high pitched annoying exhaust bit. Do what I have done. Don't think about it, just do it.
