If RPi's full GTS exhaust system or rear mufflers are too loud for you please check this...
I asked RPi if they can make a quieter exhaust for my E60 M5 with less sound than their new GTS system without effecting the power of the car, and they were kind enough to accept my request
They will make a custom section 3 "rear mufflers" with the same internal design as their current GT exhaust section 3 but with bigger mufflers to reduce the sound level. It will be in top notch quality, tig welded and in mirror chrome finish.
The reason for my request wasn't because their GTS exhaust was too loud for me, yeah it's loud, but in a nice lovely way. It's because I'm shipping my M5 to Europe this summer and I don't want to be stopped by the police, specially in Switzerland!! Last time I drove my Ex-Kelleners M6 in Switzerland I was stopped 3 times and got tickets for sound violation!!
This special RPi exhaust section 3 will be more expensive than their normal one for sure, as it will be produced in a higher quality and a very limited quantity! the more buyers we can get the cheaper it will be.
So if you're really serious about it and willing to pay extra money for it, please inform me so I can get a final price from RPi on this exhaust.
I don't know if you know but I have used a RPI ST system and taken it off for being to loud and to much drone so I have been pushing for this very mod (larger section 3 mufflers) for ages so I have to say a big thank you for the helpful push on this with the brilliant guys at RPI!
I will sign up now, I want a full system. if a deposit is needed to secure KSA/RPI just PM me and I will pay now.... I am ready and have been for ages lol!
Did they say if they are keeping the RPI tail pipes as on there normal section 3? Hope so.
