Agreed, it's not for everyone. But you can't argue with the numbers. That setup makes significantly more power to the wheels. That car with their exhaust, pulley, tune, AFE filter and RPI scoops made 392hp to the wheels that same day.

Wow, that's incredible! What are the RPI scoops?

Don't be so sensitive. I meant it as a compliment to the company. Most US businesses don't even return an inquiry unless you get them live on the phone. The fact that these guys are all the way in Slovenia and still get back to a US customer within 24 hours every time is impressive.

That was the key for me. The shop that I installed it at has a fully catless setup which adds even more power and torque than the Akrapovic, but it's pretty loud. It sounds sweet, but not for me on a daily driven car. Check it out.

I think I've seen that black M3 on M3post. Is it the one with racing seats and roll bars in the back? Kind of odd the guy got a sedan, must really be in to touring car racing.
