Madness V2 Catback MINI Cooper S Exhaust for R53

I really recommend this catback exhaust.from a performance aspect you will feel like the car wants to go faster , you really feel power unlocked. The exhaust note is reaaly what i wanted (Deeper but not much Louder) unlike other catbacks that are really noisy.Also the popping sounds are much louder and clearer making the car much more fun to drive. I give this a 5 out of 5

I was saving my nickels and dimes to get an exhaust to go with the other mods on my mini. I stopped by Madness and saw the new exhaust. I drove off and then came back and ordered one. I had Madness install it. The exhaust note is deeper and not much louder, which is exactly what I wanted. I want to feel the performance gains not make lots of noise. As with each preceding step the car became easier to drive smoothly as the power and torque increased. On trips to the Oregon coast over the coast range I average 30 MPG. The Madness exhaust was the crowning touch when arriving at stage 2. I am a happy camper and it's pretty too. ex997guy

I had my Madness Exhaust installed on my 2004 Cooper S locally for $80 (I guess not more than couple hours labor - seemed very reasonable) in early June. With 3 months of fun under my belt, I am really enjoying it. At first it was just the nice sound - little louder and definitely deeper. Then I noticed that on my usual commute I didn't need to downshift to 4th on a certain long uphill, but was able to stay in 5th - yeah, little more power. Then after several gas fill-ups I noticed approximately 3 mpg increase. Cool - better sound, more power and increased mpg. Sometimes I wish it was a little louder, but then I love the sound of a SS Chevelle with glaspacks. The sound is just right 98% of the time.

This lives up to it's name, MADNESS! I was worried it would be too loud or sound like a Honda (two stroke weed whacker). Instead the sound is just right at WOT, deep and rich. Heck my cold air intake is louder! The install was easy, hard part was getting the stocker out. Overall I absolutely love it, my only complaint is my mileage is going to suffer as I tear around listening to it.

After years of trying numerous exhaust systems on my heavily modified "S", the Madness catback system is hands down, the best on the market. With it's unique, aggressive tone, one can take pleasure from the growl while running wide open yet still enjoy the likes of driving down the freeway without wanting to pull your hair out from the mundane noise that most of the after-market systems have to offer. The catback system, coupled with V2 MM Header also showed substanial gains on the dyno as well. A must for any Mini Cooper enthusiast!!
