Development is still under way but it sure looks promising :thumbsup:

"Our developement work on the headers and metallic cats now stops, and it will continue after Aug. 21, possibly on a M6 car.

I can anticipate you that the stock engined M5 car we worked on, does have an impressive 530 Hp (engine hp) , and that our cat-back system lets it jump to almost 544 Hp. Unfortunately, this gain is concentrated higher in the powerband, mostly from 7000 to redline, as the torque curve at low and mid rpm is almost unchanged."

I assume this is with stock headers. 543.7hp is very impressive and they look great too!

Any idea what they weigh (kgs) compared to the stock exhausts?

hm, when i read the comparision pdf i see, that the oil-temp was just 34degrees celsius? did you test the engine with that low oiltemp?

on the other hand it was quite hot that day and 530hp seems to be very strong concerning temps above 30degree celsius...

 

[MortenDK]

Also, this one has 530 hp

Prad is rwhp? Is the engine HP measured directly from the flywheel or calculated from the rwhp?

 

[MSB]

[alsahher]

My guess is that is is an calclation from rwhp. Not very accurat IMO.

How would this compare to RD headers and chip...Are RD italy a recomended

after market supplier?

 

[Gustav]

I would not choose RD based in what I have heard. Do a search on the forum for Racing Dynamics.

Hello Gustav. Is supersprint available for E60 M5? If so where can you order it from. Can you buy it in the USA? Also what do you know/think of the DMS chip? For customers that live in the States,how can we get the DMS chip? Your response is always valued. Thanks.

Any sound clips ?

 

[mgmbh1]

The Supersprint exhaust looks really good, I just wish that the tips would not stick out so much from the bumper. Is there any way to order it with shorter tips?
