Maybe old news for some but also new for others.
Supersprint has now a complete exhaust kit including downpipe, race cat and complete back box system. The car was measured 417 HP without any software update. I like it http://www.supersprint.com/ww-en/bmw...ith-valve.aspx |

I call BS. No way a race cat/downpipe and exhaust only generates those numbers.

The complete system with down pipe, race cat and back box has good price compared to other systems. If the figures are BS, I cannot tell... |

Isn't the M2 close to 400hp stock? Another 15-20 hp from a downpipe seems reasonable to me.

For 200 cell, you shouldn't see it if the sport-cat is designed well.
But I doubt that stock figure was bellow 340 HP, it's more realistic that sport-cat + back muffler gave another 30-40 hp which is realistically possible. |

I thought it sounded pretty good, especially the drive by video. The stationary video seemed like it was inside a garage so maybe it didn't give off the best sound.

The figures are feasible alright,like has been mentioned another 20/30hp ( at the crank ).
Does this exhaust have the twin pipe technology because it's not clear as the list of parts doesn't account for this and would this throw a cel by any chance ? |
