WORLD MOTORSPORTS: What were the Dyno Figures for Before and After these Downpipes were fitted?

The street-legal downpipes actually make more than the off-road downpipes.
However, when paired with a good tune all of those figures change. With a proper tune the off-road downpipes make more horsepower than the street legal downpipes. Both sets of downpipes, however, make more horsepower when coupled with a proper tune.
With all that being said. The off-road downpipes are very loud on an ML63 and if you are planning to install them without a tune they will also trigger a check engine light for cat inefficiency readings. The street-legal downpipes will not trigger a check engine light.
I was buy and put on auto RADO downpipes and very happy :-)
Engine work was louder and I was tuned my ML63 for 660 hp and 1010 Nm.
0-100 km/h car get for 3,8-3,9 sec on RaceLogic. I think it not bad

Great numbers and I'm glad you loved the downpipes. I may have a heat exchanger available for the car soon too.

Could you please provide before and after dyno graphs comparing a tuned (stock) ML63 and a tuned ML63 with the off road down pipes.
Could you also provide pricing to 2167 sydney Australia.
The only reason i haven't bought a system is because no one can provide me with the data so i can make an informed decision, i went as far as emailing Rado direct and got a reply from a distributor which struck me as odd.
If I cannot get a concrete response I may just modify the OEM downpipes and put HJS 300cell metal core high flow cats in place of the stock units since mine ar slowly reaching the end of their life.
