See what our customers think about our exhaust!

Hey George,

I just wanted you to know that I am very pleased with the new Mini- Madness OEM exhaust system you put on my Cabrio. It is measurably
better than the Borla exhaust we replaced. The horsepower increase,
and the sound of the exhaust are fantastic. As always your attention to detail in developing your own parts makes them amongst the best after market tuning products available for Mini Coopers today.

Thanks Again,

Randy Drullinger


MADNESS! (MiniDrew)
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.


A complete package, at last (Anonymous)
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.
