I have both.

Had Remus for about a year and really liked the deep growl at low RPM then brought the car in recently for installation of Quaife LSD. The owner of "At Speed MotorSport" had a cancellation of Dinan exhaust so he gave me a great deal (30% off).

My impression: both sound very similar overall, subtly aggressive but not as loud as RPI. If I have to do it over again then Remus is a better value unless I get a great deal on Dinan.

By the way, I will put my Remus exhaust on sale under "Private Member Classified".

 

I love my Dinan exhaust. From what I've read, it's not as loud as RPI which I'm very much ok with, but you'll definitely hear a growl from the Dinan exhaust.
Whichever you choose, I don't think you'll be disappointed. It just comes down to your personal taste for sure.

 

it would most probably depend on whos doing the install but its been said that you shouldnt spend more than $150 for install. the RPI axle-back (525,530,545,550) is a clamp on and there shouldnt be any welding done.

 

+ 1

If you can grab his, it would definately be the best deal out there!

Otherwise let us know, they're in stock

 

RPI it's the one

Does anything need to be done, as far as computer reprogramming or any adjustments after putting one of these exhaust systems on? I have a 2005 545i and am thinking about a direct replacement.

Thanks.

 

No computer issues, take OEM off, install new exhaust. On my 545i there is vacum line that went to a valve on the OEM exhaust. Didn't do much if anything as far as I could tell. I think you are supposed to plug the hose, not a big deal.

IMO a nice exhaust completely changes the character of the E60, especialy the V8.

 

+1 for RPi!

RPi for the 550 isnt that loud at all, unless of course you rev the car up.
