Muffler Delete Pro/Con

[PREDATOR 007]

Looking to get a little more sound out of the car. Would going to a muffler delete system be a good move? Don't want to sacrifice any performance though.

[13M5F10]

You won't sacrifice performance. Turbo cars enjoy the free flow. It sounds bad ass.

You will how ever have a louder cold start, drone, and panties thrown on your car. I fixed the drone by driving in D3 and Sport Plus which kept the car out of 1800 rpm range while cruising. Besides, sounds better driven that way too.

Here is my muffler delete when I first started moddin

How much sound are you looking to add? I have an exhaustmeister that adds about 10%, most notable at low rpms and on downshifts. I'm leasing, so wanted something easily reversible, but may be too subtle for you.

[PREDATOR 007]

I'm leasing too, so I have to be able to put it back to stock. This got me thinking, does the muffler delete option require me to cut the stock pipes? I was hoping they would just slip off and slide a new pipe on.

Would like a noticeable increase in sound..

I have an RPI system and it makes an awesome sound.

A full system is best. No mufflers, no resonators = more power and amazing sound.. I would just store my stock exhaust until the end of lease.

Be carefull with all those telling you about how loud and great there deletes and full systems, a lot sound great for five minutes but the volume and drone will drive you mad... if you like being centre of attention (good and BAD!) then go for it but if you use your car regularly and have close neigbours and worried about the cops beware... the drone of my muffle delete drove me and my wife mad- could talk through it and had so much pressure in the Hz generated it gave me regular head aches!!! You ca't drive around it as its normally at 1500-2000 rpm, on light throttle, crusie and deleration.

I went for the Agency power Ti system as it was well priced even compared to stainless steel systems, it was easy to fit, and sound nice but not to loud and fully cured the drone period (no rpms or throttle positons or cruise)... cold start is a little louder than stock without being to offensive either.

You might want to consider AWE's rear boxes as I have had good experience with their products in the past.


.... remember, avoid drone at all costs, it makes for a misserable driving experience for you and others....

All axel back mufflers or deletes will require cutting the stock mufflers which is reversible but will require the muffler shop to weld it back on.

full exhaust system would avoid that but as you know it's costly.

It all depends on your personal choice. I have had this system on my car for a long time and drone isn't my main concern / worry like you. That said my M5 is not a DD. I drive it on the weekends and it's for pleasure. Personally I would recommend anyone looking to do any exhaust system to decide if they are going to fit downpipes. If they are I would recommend doing downpipes first. The sound impact is immense on any system, so in many instances a stock exhaust could suffice.

muffler delete does cut from a certain point but bmw sells connectors that slip over the cut to revert back to stock, does not have to be welded.

i have turner delete and its not really that loud at all, easy to converse in cabin with windows up or down, it just adds a nice bark and growl.

Well is it noticeably louder than stock? If it's not much louder, is it really worth it...

I have wired tied my flaps open to give a little extra sound.

Did you look at my videos? It's louder outside over stock. Inside cabin is not much louder than stock.l but as others have mentioned you do have that drone at 1800 rpm range. Again easily fixed driving in D2 or 3/Sport or Sport Plus. Keeps your car in a different RPM range. Besides, car is more fun in those settings.

[apexlocator]

I agree with ur20v, drone happens at ~1700rpm and its bothersome for me. People will say stay out of that rpm range when driving, but everytime you slow down to a stop or in a parking structure, you WILL be hitting 1700rpm alot. Of course personal preference/taste dictates. I recently heard a turner delete/ams catless dp m5 and it was LOUD; cant imagine how much worse the droning would be.

I think you have your answer right there.


But seriously, most of the complaints with the deletes are the drone. If you don't mind it, its the cheapest and easiest option to get better sound out of the car. A nice option to have when getting an actual system, besides the ease of installation, is the ability to hear sound clips of different exhausts and getting to choose what you like best. Or even a step further, and getting a valved system, and having the ability to change the sound at the push of a button.

Without trying to turn this into a "let me sell you something" post, if money is an issue, I am blowing out my in stock inventory of Eisenmann sport and race systems for only about a thousand dollars more than a Fabspeed bypass pipe would cost you. Let me know if that interests you at all.

Yeah, the vids are nice. Trying to figure out the drone sound that people are talking about. I assume that it is mostly at highway cruising speed. I take it that you do not find it to annoying.

[bigtex]

For me the drone is minimal as I have stock resonators in place, deactivated active sound (a must), and only drive in D2/D3 or S2/S3. Deactivating the active sound made a huge difference.

Exactly what I did and drone was barely there.

[ur20v]

Go full system or axel back mufflers...

Drone IS a problem- you would be suprised how much time you spen around the 1800rpm - accelerating, slowing, cruise/steady throttle (at speed limits) and it is THAT bad it WILL give you a head ache... you can try and drive around it but that is a pain trying to hold res up and is not totally successful as you still have to pass 1800rpm at some point.

Cold starts are a problem both at work and home... neighours complained even though my garage faces away from them and I start the car with the garage door down and the walls covered in accustic foam tiles. Whats even more suprising is they have never mentioned my GT3 with full race AWE system!

If you are used to loud exhausts, don't mind the bad reactions of others (police, friends, neighbours, business associates, employer and employees!?) and can live with headaches even on short trips great, go delete.

I lasted 2 months before removing them and doing it right, just wish I did this first time round and not wasted MORE cash and time. Don't get me wrong, I have had loud cars and bikes all my life its just the drone pushes this system to far over the edge.

It's annoying in comfort and D1 with ASD enabled. I disabled ASD and drive in D2/3 - Sport +

Same here
Whenever speed limit needs to be obeyed on highway you drop to 6th gear and it stays around 2-2100 rpms and no drone

Daily driven catless rpi grm for over 40k miles with this set up
Asd been disabled only 10-12k miles ago
No better system for m5 f10 IMO

[TheHouseWon]

Slightly off topic but how are the Titanium exhausts compared to SS? Specifically the Agency Power system.
