You read that right, I want to know the quietest aftermarket catback system available today for the r53.
I want a hp gain but not a LOT more noise vs stock. It's my daily driver, 30 minute commute 1-way, and I don't want to appear as a "tuner" (no offense to the tuners!)

 

I ran one ball mod, JCW full cat back and with resonator delete, Magnaflow and ALTA on my JCW. Of them all the full JCW set up worked great but some said at idle my MINI sounded like an electric car....hahaha.

 

Check out our Stratmosphere resonated exhaust. It makes the most torque and doesn't drone. We put them on all our customer cars and they are always happy. It's a little louder at idle but not ricer. Then has a good deep and mellow tone.

If you don't want loud Magnaflow would be #1 to avoid as they drone bad.

 

magnaflow is not the choice for you if you want quiet.... the JCW or strat would be your best options

 

Awesome thanks for the feedback!

 

I was looking for the same type of exhaust for my wife Mini. Thanks for the info.
