Louder, but not loud to where it takes away from the driving experience. Even with the windows down it is just the right amount of sound - this is what I'd expect the M3 to come from the factory with. I've already put 200 miles on it since Friday and it is the best bang for the buck you will find.

I drove an E92 with a Meisterchaft GT2, and although it sounded amazing it definitely added some drone that could get old if you DD. The Z06 I sold in order to get the M3 was the definition of drone, not only could you hear it - but you could feel it. Engine swap, cammed, full headers, cat-less x-pipe, aftermarket exhaust - the drone would literally make my fillings hurt after about an hour cruising at 70MPH. My solution, drive faster |

Can someone throw a link to the finalised version of the top entry diy method please. I've read various posts on different methods and would like to find a method that gives me as close to the M performance muffler as possible

There's a j*ck*ss with a Saleen Mustang that trolls through my neighborhood at 30 mph and I can hear it coming for 1/4 mile; that's too loud for the street. Last edited by serranot; 03-11-2012 at 09:49 PM.. |

Thank you for the explanation. By this definition, my car does not drone at all. Since the mod, I've gone over 70 mph and haven't heard/felt any vibrations at all in my car.

I guess it depends on what you're after
I wanted something that was similar to stock, but a little louder Original mod is just that If you are considering some of the aftermarket options Then probably you are in, what I at least, consider the loud group Nothing wrong with that But I don't want an exhaust that I worry about every time I pass a cop etc I'd say my mod is stock + 20% more volume ACM was at least 50% louder

I don't want it to be 50% louder. I wan't it to be about 10-20% louder at WOT and pretty much stock at cruising. Drone is an absolute no no. Everyone has different requirements from an exhaust and I'm definitely on the conservative side |

In response to pure volume I still would not say the ACM is 50% louder just moving around town, but yes it is louder than stock - but from what I've heard in person still a quite option in comparison to other exhaust.
In regards to drone/resonance, the ACM drones exactly the same as the stock exhaust, it is just at a slightly higher volume. With both those points made, the M-Performance Exhaust will do exactly the same thing. From my experience riding in a car with one the drone is just slightly more noticeable due to the different pitch caused by the different type of metal. When I first read this exhaust drones I thought I had decided right there that I do not want this. I came from a car that droned horribly and wanted to avoid that at all cost. What did me in was when a customer at ACM allowed me to go for a ride in his car while I was getting some other work done. I'm glad he did, because it saved me $3-4,000 on a different exhaust system. Not to say I won't still go the route down the road, but for now I saved a ton and got the incremental increase I needed to enjoy the car a bit more. This exhaust, like all options, is not for everyone. If you are considering an exhaust, I do urge you to try and get some seat time in a car with the mod before drawing a conclusion, even more so if the alternative is the M-Performance. It may be just what your looking for at a fraction of the cost. |

When I bolted mine up and drove it the first time, it exceeded my expectations. It was *exactly* what I wanted. It sounds like you are looking for a similar sound. |

i would want to change my driving to suit the exhaust avoiding certain gears or keeping below a certain speed with the original mod, i drive the same as i did before the mod except i get a little bit more sound what would rock is a switch on the inside that would switch from ACM mod to original mod i'm sure it can be done and would probably still be cheaper than the M performance exhaust

So back to the OP question, I think we all agree that the M-Performance Exhaust is way overpriced when you get not only a near identical auditory experience from a modded OEM exhaust for a fraction of the price.

I think if you are unsure of which way to go with the OEM mods, this will probably be the way to go
1) Start off with the old sytem OEM mod. Replace all perforated holes with solid ones 2) If the car is still not loud enough, then do ACM method. Yes, you'll have to cut open the exhaust twice, but you can't reverse the ACM method (cheaply) once it's done. Even if you did both, you'll still would have spent less money than buying those expensive exhausts IMO. I'm going to go with that route. |

Depending on the system, the loudness of this bass hum and the frequency range that it is present at will vary. You really don't want it between 2-4k rpm, becasue this is where we do most of our cruising around. Honestly....can give you a real headache.
