How loud is a muffler delete?
I know this is a popular route for the F22. I've watched a number of videos and I think it sounds great. The videos make it hard to gauge the volume, though.
Is it obnoxiously loud? I'd like to hear my car when I accelerate, but I don't want to sound like a high school kid setting off car alarms, either. From what I've read, the muffler delete isn't as loud as some people expect because the resonator and downpipe still provide some muffling. So what's the verdict on loudness? Is just replacing the resonator with straight pipe a better alternative? |

with a catless DP its pretty loud. 95 DB id say.
City Traffic (inside car) 85dB Train whistle at 500', Truck Traffic 90dB Jackhammer at 50' 95dB Subway train at 200' 95dB The drone and cold start is whats loud. Driving its decent, but your GF/wife will hate it.

Yes midpipes will add volume to your exhaust

You do have a lot of options to upgrade the sound anyways .. Downpipes, midpipe or axle back should do it

Good to hear. I've seen a lot of youtube videos and I like the sound. I'm just not sure about the volume, since it's hard to gauge that in a YouTube video. If it's as loud as a subway car at 200 feet (thanks bryan_f22) it might be just a bit too loud. |

do you want a louder exhaust or actual performance gains?
I think a catless DP with resonator delete would probably give you a nice boost in power and sound but not drone. You can keep the stock muffler. The MPE or Dinan wont do much or add any power and that money will best be spent on a tune. Mike can sort you out with whatever you decide.

Get a catted Downpipe. No cel, passes all emissions. BMW can't say anything. Get the JB+ or Dinan sport, both can be taken off in the parking lot before you bring it in for service. Or just get a ECU flash that will remove the CEL. Make sure you go with a good tuner so it doesn't throw a DME tamper code.

How bad is the drone? I already did the resonator delete and it made a difference but still not that loud.

drone on delete is right around 3800 rpm, with a cattless DP youll drone at 3800 and 5500 rpm.
At first its pretty bad, but as time goes on, you get used to it and it does get a bit quieter. Cold starts are loud too, but if you give it a little gas it gets a bit quieter. you can hear the drone here: when i take that right double apex at 3k rpm...

It vibrated very bad with a certain tune i ran for a week during cold starts. You can always have the muffler shop fabricate a J pipe with your delete to remove any drone.
