Popular exhaust questions....
i want to limit my modifications on the m coupe and plan on strickly exhaust and wheels. I do not plan on tracking this car but want a better sound. So my question, which exhaust....
priced from cheapest to most expensive 1.RPI- i have heard its much lighter, but weight isnt a huge factor for me 2.RE Diablo- slightly more expensive and slight heavier then rpi 3.eisenmann- the price has almost doubled compared to the rpi. is it worth it? 4. supersprint- known as best of the best once again im not looking to race this car, so the latter two options arnt very realistic in my mind. i have also consider headers, section 1 and running catless or with race cats, and section 2 with x pipes. Im not as interesting in these products but general information would help. I would like to hear from owners, distrubutors and all other with more knowledge. Any comments, complains, and information would greatly help me. Thanks and im glad to join a unique group of motoring enthusists Last edited by Calichase; 05-11-2014 at 04:33 PM..

Not sure if you've seen this thread or not, but this is a great place to start...
http://www.zpost.com/forums/showthread.php?t=680796 There's basically no HP to be gained (even if you did gain 10HP it would not be feel-able), so it comes down to whatever sound you like, and how loud you want it. I personally think most of the exhausts out there like RPI, diablo, and eisenmann are highly over-priced for what you get. Good quality stuff, seems like a lot of money for just a gain in sound..

Good input above, I'll add the following.
The key questions are: How loud do you want it? What kind of sound (e.g. exotic or low growl)? How much drone can you tolerate? Budget, and can you wait and see what pops up used? Just sound or do you want performance gains? Start the research here here for sound clips, db levels, drone, comparisons of many options. The RPIs sound great, and exotic, but they drone a lot, and they're very loud. Diablos are more growl, lower, but also have a lot of drone. (Had Diablos at one time, and Remus, now Eisenmann Sport--all bought used). Axle back adds sound, not power. RE xpipe adds a lot of sound, pops, and burbles. Supersprint xpipe does add sound, but not as much as RE. (No idea why, it's just I've heard the super sprint before the X pipe and after the X pipe and there's not much difference. And also for the Eisenman sport before, and after the X pipe and there's a world of difference.). Again, sound, not power. Headers, cats etc. add complexity, and potential cost. They're worth it for performance, but it all depends on your goals and budget. Lots of threads--see mine, it's recent, to start with. Many others on this topic too. Congratulations on the car! You're going to have to work to keep the mod-monkey off your back! Last edited by Finnegan; 03-05-2013 at 03:22 PM.. |

Ran alone, I think the Arqray may not be as aggressive as the others, but it does a fantastic job of giving you a clean crisp and deep note when you do other modifications to beef up the sound. Take a look if you want...i think it's a nice alternative that not many people consider because of it's rarity. Cheers. http://www.zpost.com/forums/showthread.php?t=809552

i would prefer a lower more growling kind of sound and drone doesnt bother me(e46 experience ha). my budget isnt really the major problem but i wouldnt want to spend over 2k on anything. is there any problem with getting a used exhaust/muffler?? i dont want to have to mess with emission, been there done that, so headers and catless are out but an x pipe might be reasonable. Bu thanks for all this information. keep it coming |

Stromung might fit the bill, as would Diablo. Less drone with the Stromung. Nice and deep and great growl. RobMCoupe has one. Gferil's generic reasonator (custom) might fit the bill too. Think he's going to sell it since he's building a new generic system. If you live in NorCal, chances are you might be able to meet up with a number of folks to have a listen inside and outside the cabin.
No issues with buying used exhaust. As long as you see pictures, and it's from a reputable seller, you don't have anything to worry about. You can check the I trader rating. You can also just start off with axle back. If you want more sound, if you want more pops and burbles, you can always add an xpipe later. Wheels? Can't go wrong with Apex. GB starting on EC7s too. Thread on that today. Thought I'd add that since it's up next! |

I put the RPIs on my car last time I was home and I love them. There is definitely a big difference in weight, although I didn't really notice it driving in the few days I was able to drive my car before leaving. They are very loud and sound great while doing some sporty driving or around town, but on the highway they can be too much. It can be a little hard to hold a conversation over the drone at highway speeds.
Congrats on the Coupe, and in the best color too!

I hate to bump this but my question isnt worth a whole new thread.
I have a few Questions concerning exhaust upgrades for ///m coupes 1. I am looking into a rogue x-pipe, An axle back muffler, and an evolve tune. I live in md where emissions laws are pretty strict. Will I have any issues? These modifications shouldn't throw codes at all, but I might fail for being modified in the first place. Maybe someone from md can chime in. 2. For the axle back, I'm thinking about re diablos or rpi's. I have searched and read all the great exhaust threads. There really is some great info here! My question is that I can't seem to find how much wait is saved by the rpi's. I know the diablos shed about 15 lbs compared to stock and I think the rpi's are around 30ish? If I am understanding correctly, is that wait really noticeable, or just a nice pro to the rpi. From what I have read, the rpi's give a louder more exotic tone while the diablos give a lower growl. Would the addition of the x pipe just add the gurgles and pops and maybe some more sound? I was also considering eisenmann race and ss power loops but don't see the gain for that price, but I may be wrong. |

X pipe and cans do not effect emissions at all. Non issue.
RPI or Diablo will save weight vs. stock. Not enough difference between the two (or to stock really, unless part of a total car reduction strategy) to be concerned with. RPI or Diablo + X pipe will be loud. Very loud. And lots of drone. Recommend starting with can then considering x pipe later. If you don't like drone stay away from RPI or Diablo. Stromung is in the same price range and much less drone. Eisenmann Sport or Supersprint Powerloops add sound w/o appreciable drone. All depends on what you're after in terms of sound/price. |
