Ive had many products on my cars over the years. and supersprint was among them. I always dyno my cars and supersprint was always the highest power numbers from my personal experience. Also in independent tests they are usually very high also. Im not sure why you dont like them. Can you elaborate on this. Also what company do you recomend. If you are so sure that Supersprint sucks.

have you seen the holes, cracks, seam breaks on the e46m3 headers, mufflers, and midpipes? those of us that track the car have all had it with the extremely poor quality of their craftsmanship.

also, don't forget about the rust.

there is a reason you will not see superschit exhaust on ANY PTG or similiar pro level car running today... you'll see them at club level cars because, frankly, lots of people don't know better...

i guess for street blingers who never come close to the car's design limits, the superschit stuff won't get pushed hard enough

Actually i have quite a bit of track experience. Actually alot of it. Ive also been to countless driving schools. And have tracked every one of my Mcars to date. Ive never had a problem. But then again i dont use supersprint all the time.

By the way you still havnt said what you recomend if anything.

don't be so defensive and start listing your driving experience...

have a read on this regarding superschit: http://bimmer.roadfly.com/bmw/forums...6926507-1.html
those are my buddies and i can get you the pics if you are so inclined. as you can see, SS even responded in that thread.

my recommendation isn't for everyone. if you're not ready to prepare your car to come in first under the rules, then you are not ready to compete. you are an "also ran". my setups are pure custom fabrications with alpha-n tuning. exactly the same process that the top level winning teams in any race series uses (that is if they are NA engines).

but if you really need an over the counter setup for the e46m3, the BEST one tested and built properly out there is the EvoSport Jet-Hotted headers. design, construction, quality control, and tuning are all done properly with this setup.
