RPI exhaust for X5M, X6M
Been looking for an exhaust option - would love to do downpipes and a full exhaust, but all the manufacturers are telling me I won't pass a NY inspection with downpipes, even catted and with coding, so it looks like I am limited to an axel back system only.
I'm not a big fan of the Meghan exhaust. The Dinan exhaust doesn't make it move. I like the looks and sound of the Meisterschaft and Eisenmann, but not the price tag. Akro isn't for me, either. I really like the looks and sound of the RPI exhaust, and it hits a nice mid point in price. So - does anyone have one? How did you like it? where did you get it? Any other options out there that I am missing? Here's a pic of the RPI exhaust: |

I can't speak for the X5m, but I had the RPI exhaust on my M3 for a total of about 30 minutes.
It sounded great, but was drone city and I couldn't take it.

Can't comment on the x5m either, but I have one on my z4m...and it sounds awesome, throaty and has a bunch of burbles and pops when you release the throttle. Did you try searching YouTube for some videos?

There are several videos on youtube - I really like the sound. There is also one taken from the interior, but all those videos are of limited value, other than giving you an idea of what they might sound like.. Here's a couple: https://www.youtube.com/watch?v=tMRcxQl56IU https://www.youtube.com/watch?v=67XE1p34lM0 https://www.youtube.com/watch?v=zR94wksoFHU https://www.youtube.com/watch?v=soppIidQXFY Last edited by upstate650; 03-04-2014 at 08:50 AM.. |

Exhaust preferences are pretty personal, but all input is appreciated. |

I like exhausts that have a little bit of a "blurble". He valet driver pulled up his vehicle and it didn't sound all that much different from the stock exhaust. His X6M is heavily modified, but the exhaust is just like what you posted up.

Thanks for your impressions - so not much louder than stock at near idle? Have you ridden inside? Any drone? How does it sound when it is being pushed? Based on the videos, the exhaust seems to open up when it gets into higher RPMs.

Correct. But I have not yet ridden inside, so cannot give you any feedback in that regard.

Be careful looking at vids online. The first two you posted aren't just the RPI exhaust but they are mated to TTR's headers which gives it a deeper rumble that isn't there with just the exhaust. That first vid is actually one of my favorite sounding setups on this car but sourcing the headers was too much work so I just decided to go with Dinan instead. P1ets's right when he says RPI sounds pretty close to stock, at least thats the impression I got when looking into it so I scratched that off my list immediately. What are you looking for in terms of sound (exotic, deeper rumble or just want the look of bigger tips)? I'd say eisenmann is the most exotic sounding, dinan is the deepest sounding and akra without dp's sounds marginally better than stock but is the best looking system IMO. I've heard quite a few setups for the M's in person and personally liked Dinan the most, I'm excited to hear my exhaust paired to some catless dp's this summer. Performance wise they are all the same and the stock exhaust is extremely efficient so you won't make any noticeable gains.

How about Gintani? Anyone ever heard one of these in person? I am also interested in a axle back for my M. Wondered if not having a big muffler like Gintani makes any difference in sound or drone?

Have you heard an RPI exhaust when the vehicle is opened up? I'm not at all opposed to an exhaust that is pretty mild near idle but wails when it is pushed! |
