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.
You've put a lot of thought and effort into your system, glad it works for you.
I just added a custom Magnaflow axle back to my Invidia midpipe and think the drone inside is way to loud. I plan to add the stock pipe back, resonator, and cats back in a week or two and just have that with the Magnaflow. Thoughts?
I might add a F-sport intake as well, if the stock pipes to the Magnaflow don't offer enough deep tone feedback.
