I bought the Flowmaster American Thunder axle back when the stock active exhaust had run its course. I already had a X pipe installed prior. The system was a disappointment unfortunately. Build quality issues prompted me to send it back.

I ended up going with this Corsa system. So much better in all aspects. It’s expensive though. I would say do a mid-pipe change and try that for a bit. I’m now debating if I want to change out the X pipe for a Borla Switchfire.
