2014 650 Coupe Muffler Delete Sound

This is what I've done to my Alpine 650 coupe so far.. Muffler delete with dual staggered 3.5" tips done by Exhaust Pro over here in southern Cali, gloss black roof, white painted reflectors, tinted lights, BMW black grills.. I'm waiting on the open air intake that's being developed for these cars by Igor over on 5 post and then going with the Burger stage 1 tune!

Click the first picture, it's a sound clip. There is some drone at 2k rpm, it's not bad but the cool thing about this car is I can put it into comfort mode and put the shifter in normal drive and it keeps the rpms at around 1,500rpm and then it has no drone, once you're in sport or sport+ it keeps the rpms right around 2k and you can hear the drone, i kinda like it though. It has a really nice exhaust note now and is not too loud or anything, just sounds amazing with that twin turbo V8! I left the resonators on and only removed the rear mufflers. There are 2 vacuum lines that need to be plugged and also there are 2 grounding straps that need to be attached to the new piping. Exhaust Pro welded on a threaded boss for each side and screwed the strap in the same way it was on the OEM exhaust, really top notch professional work!

100% reversible and easy for a shop to do. It may be around $75-100 to put it back to stock as they just have to cut off the new piping and re-weld the oem mufflers back on and attach them to the OEM hangers.

Thanks! I also saw your review on yelp for this shop. I think I might give them a try.

By the way these are the exact tips I purchased and had Exhaust Pro install. No shop just has these laying around and you would need to order them anyway, you will not find a better price than $100 for the pair anywhere!

Thanks for the link, do you mind sharing the price paid to Exhaust Pro?

Just give them a call, they are easy to work with and I'm sure will give you a price/estimate over the phone. It all depends on whether you bring in tips or they have to custom make their own or order a set.

Thanks man! Everywhere I go someone asks how many thousands I spent on exhaust because of how exotic it sounds, I just say BMW did the work with the motor, I just removed the silencers!

I did it on my F12 650i, in my opinion it sounds to say the better too old school V8, tomorrow I'm going to install new set of mufflers and I'll let you know the results.

I would have to completely disagree with you here since I just sold my 2006 supercharged and cammed Saleen Extreme with long tube headers, no cats, and a full exhaust. That was old school V8, this car sounds nothing remotely close to it, I get an exotic deep and tuned V8 sound like you would hear from an Aston Martin or Maserati with exhaust is the closest I can compare the sound to.

OK, now I'm fully satisfied, BMW OEM mufflers. Great sound and factory looks.

I put in the N63TU JB last night and went for a few pulls.. The car pulls like a freight train to redline now! Before the JB I felt like I was losing some power up top as the car had great low end and midrange power but now it's like a whole new animal! I launched the car at about 2k rpm form a stand still and it will now light up the tires all through 1st gear and turn on the DSC if I let it, it didn't before. The low end and midrange are both much stronger and the top end doesn't feel like it's running out of air, power is linear and smooth and best of all, no codes or any issues whatsoever, just pure performance and power!! Thanks Terry and BMS!
