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

If i understand correctly their dyno showed 315 whp (radleistung) so the 417 engine hp number is just bs.

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

whatever the number is
supersprint makes top notch products

Totally agree!
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...

What do you guys think of the sound? For a complete exhaust, I'm not that impressed. Maybe it's just the video, but the MPE sounds better to me

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

Any cel if just installing the sport cat?

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 ?

FYI, based on the graph, its 417hp PS not SAE measured HP which is less ~ 411 SAE HP. In Europe, they rate their HP figures in metric (PS).
