Hi everyone, I currently own a 09 650i convertible
i was thinking going to the shop tomorrow to get the resonator removed and keep the stock exhaust...
will this make the sounder louder? or should i not even bother doing so?
Wow. When it comes to the sounds of these cars we have been beating this subject to death for quite a while but it all comes down to what you want. How about putting in the AFE intake and deleteing the air box? I've heard that soind and it sounds really nice. Everything else was stock. Let us hear how this setup sound eurowned.
I should be receiving my AFE intake this weekend. I'll post vids up shortly after the install. After WhiteDropTop and Eurowned post of vids of their respective set ups, ill make the decision which way I go; then will post more vids.
the iphone 4 video sound quality sucks, ill try to use other devices to record the sound,
it actually sounds alot better than the video does.
ill prod take the one inside the 6 and outdoor!
it actually sounds alot better in person, idk why it sounds like that in the video
but yeah you should def get the muffler out! it was freaking heavy haha
I like the sound a lot. Is it legal for a car without muffler? If ilegal, I better go with the magnaflow catback system. Similar sound, $1000 more, but definitely legal.
I would think the resonators and cat would serve as a muffler. As long as you are not exceeding and noise laws, it shouldn't be a problem. Mufflers are for noise control and not emission related. You guys are making me want to make a trip to the muffler shop.
eurowned, car sounds awesome and really isn't loud. How much difference is noticed at highway speeds.
What are the difference in sounds when removing the resonators vs. the mufflers? I was initially going to remove all three resonators and add an x-pipe but now i'm confused and indecisive. Can someone please clarify?
We are not sure yet really. I have magno flow mufflers and removing all three resonators and adding an Xpipe next week. If I had stock exhaust I would remove the stock mufflers instead fo the resonators just for the weight savings. Got to be close to 75lbs or more I would think? Thn if not loud enough for my taste I would remove one of the resonators and so on.
just for the record, state laws govern what you can and can't do to your motor vehicle.
several states say that you cannot remove any portion of the pollution control system.
make sure you check your local laws and regulations, especially if you have mandatory inspections. if your state doesn't have inspections you just have to find a way not to piss off an officer enough to necessitate him getting on all fours to check the under carriage.
So, you'll be the guinea pig to remove the three resonators and post a clip then, right?:bigpimp: Then we can all base our decisions on the clips and reviews.
After reviewing all the great info here, I decided to replace my 2010 650i coupe stock mufflers, which is too quiet, with meganaflow mufflers and tips. I think this mod will produce just enough sound for me. Called the dealer and was told that the BMW performance exhaust is not available for 650 and muffler delete may be illegal and void warranty. The dealer asked me to wait till new car warranty expires. But I can't wait for 45 months. I will settle with less db and possilbe less warranty trouble. Bought mufflers and tips from e-bay for around $210. Will install after receiving them.
What is your decision, guys?
Nice, kbarkker. Did you remove the resonators? Will the maganaflow mufflers replacement alone enough? Saw your vid on youtube and you did not mention that your removed the resonators. Thanks.
Yes Kbakker is that all resonators removed (3) and an x pipe with magnoflow mufflers? I have magnoflow mufflers and removing all resonators Friday and installing an x pipe
Taz, 11235 for ss mufflers (14335 for polished), 35159 for tips.
W D Top, dose magnaflow mufflers alone produce louder sound than stock? How much louder? Thx.
I have been reading this thread and can't find it, lol, just kidding but do you think the car be able to pass inspection. I live in jersey and I know inspections are tight here. Thanks all
I'm getting my mufflers removed tomorrow over lunch.
I found a shop to use the stock tips.
I can post some video, but the only thing I have is an iPhone and that quality has already be posted.
