I just bought RDSport mufflers, the LA shop was moving and liquidated all their e39 parts. I got only the muffler, the x-pipes were sold out. The warranty sheet does say that its made by Supersprint.Kevin, I think you are right because I remember reading somewhere that Supersprint made the mufflers for RD Sport but I'm not 100% sure...maybe someone else can chime in.
Partlially true.True story.
Thanks for the info! Generally the same tone as a SS rear section then I am guessing?Partlially true.
Supersprint used to private label exhausts for Racing Dynamics / RD Sport througout the 90's, up to circa 2001.
Since then, RD changed their exhaust supplier; Supersprint is no longer dealing with RD, or Racing Dynamics, since about 10 years.
Those M5 E39 RD, leftover mufflers must have been produced prior to 2001.
And yes, they are exactly the same Supersprint Magnum exhaust, just with different tip style and logo.
