Good afternoon,

I'm looking at upgrading the exhaust on my '08 550 to either a SuperSprint or Dinan Exhaust. I've had Supersprint in the past and it's great, but never a Dinan Exhaust. Anyone have prior experience with comparing the two?

 

I have Super Sprint exhaust on my 550i I like how it sounds but I don't know if I get any power from it. Here is sound clip

I would go with RPI exhaust much better sound, more power then DINAN and less money

 

I would do RPI. I had Supersprint on my M and wasn't impressed. I considered Dinan, but a few M5board members in my area had them on their cars and I found it too similar to Supersprint. Although I'm not talking about the 550, I would still choose RPI. I think you'll be quite happy.

 

Any recommendations where I can find RPI products

 

Where did you purchase your SuperSprint exhaust? Also did you get the Sport or non Sport muffler and lastly did you remove the resonators?

Thanks

 

Got it from e-bay for $700 new, did not remove resonators and not sure which model I think it's sport

 

Contact Trinity Motorsports. Or, contact Eloy (President and Owner) of RPI directly. Their service and products are top notch. You will not find a better vendor/supplier/manufacturer on this board. Period!

Thanks Calton!

We do have the 550i exhaust in stock at the moment
