[] R&D
[] Race proven / heritage
[] Dyno proven
[] Durable / Quality Materials (plus is exotic/titanium)
[] OEM Fitment
[] Price point
[] Positive forum reviews

*Sound was a factor, but to me, the above balance are the objective elements I wanted to sort out and decide from there to see if sound could override a decision.

Reviewed: EVOLVE Valvetronic, IPE Valvetronic, Akrapovic Evolution, Eisenmann, Meisterschaft, BMW M Perf., Fabspeed, Challenge, Active Autowerke, DINAN, Kreissieg. Full systems and axle back only.

After all the research I ended up with one exhaust that was still KING across above factors - the Akrapovic Evolution Exhaust system. It aces all factors and considering what you get, price wise it's actually a value leader.

Does anyone have other thoughts to add? Just curious if other people when considering such factors would come up with another result.
I was in the same boat, I also compared the akrapovic, ipe, eisenmann, and evolve. I drove a car with these setups and hands down the evolve unit, I love being able to change the tone. But I guess that's just me. Also another note is, is the car bare able in all driving situations?
