I just talked to my local (only) speed shop here in Seoul concerning staging my 2004 MCS. They recommend and use Supersprint exhaust with header and am told and was shown a 20hp on the wheels gain just with exhuast mod on a 2005 MCS automatic. Is anyone else out there using Supersprint and what kind of hp gains have you seen? Your input is appreciated.:smile:

Currently we are negotiating my stage build which will include; headwork, cam, throttle body, ECU (7300 or so rpm limit), 15% pulley, plugs, coil, CAI, header, exhaust, intercooler, and possibly coilovers. (all for a good price including parts and labor). My Lil Red Rocket will definately be one Bad A** Mini when done.

 

I have the supersprint sport catback on my car and am very pleased with the system. The sound is great and it does free-up some hp, but nowhere near 20whp, probably only like 3 or 4. With the header and full exhaust I'd be surprised if it opened up more than 10whp, but it's a great exhaust system.

 

dufrinr, I would recommend you have a look at the OBX header. It is an exact copy of the supersprint sport header, but at a fraction of the cost : $175 !!!! It is sold in EBAY and that is how I got mine. I have it in my MINI for almost a year now and it is great. Cost, shipping and installation was under $250!!!. You do need a CAT, to weld to it, but the results are great. I used my Stock Cat. Notice the 10 Nt-M torque gain so uniformly across the rpm band, in the Dyno chart in page 1. OBX was going to make a Cat-Back for the MINI S, but I got a Remus catback. Just the OBX header will make you happy.

I would agree with the other post in that just the catback will not do a whole lot for you. The stock header has two CATs and the OBX/supersprint header removes one of them. That pre-cat is there only for the first few minutes of the warm up of the car. If you have the catback supersprint, I would install the header and really see an improvement.
