I am selling the Helix Prototype catback off of my Mini Cooper. Stainless steel and designed to smooth out the first gear torque curve to eliminate the drop off at just over 4500 rpms.

Catback was on my #14 Mini Cooper when it won the following autocrosses: 2004 Atwater Nat'l Tour H Stock, 2004 Atwater Pro Solo, 2004 Wendover ProSolo, 2004 Utah HStock Championship series and the 2004 Rocky Mountain Region Championship.

Not dyno'd but to my rear end made a great deal of difference at the high end of first gear without sacrificing HP and torque anywhere else.

$350 firm plus shipping anyway you want.

Sold both my Mini's to get into other forms of racing and have parted out the go fast bits. This is the last piece.

Also have a stock 2003 Mini Cooper exhaust for anyone who wants the thing. $100 plus shipping.
