Anyone had a muffler delete on 50i?
I'm just wondering how it sounds? It's an easy mod to cut muffler and remove it - won't throw a code, won't have issues with emissions, less weight, can always go back if needed and the only unknown is resulting sound - is it any good?

Any/all cars I've ever heard with a muffler delete sounded horrible to me. Full track-use cars notwithstanding naturally. Are you really trying to save weight on our bloated SAVs?
If doing this sounded good, why would people develop aftermarket systems? Granted, I'd never pay the crazy entry price for an Akra System, but you get my point. Like you said, however, you could just chop it off and see if you personally like the resulting sound, especially under load. If so, that's all that matters. Keep it that way... unless of course, you were my neighbor. ![]()

I may actually give it a shot based on this video I found yesterday.

Kinda like the SVR, but less raspy and deeper sound. I like it.

If you could do some inside cabin video shots at both gentle city driving as well as mid-throttle acceleration, and exterior shots too, we would all very much appreciate it, good sir.

from owner of this x5 that modded stock exhaust. This is what he did: 1. Cut out mid resonators - there's 2 of them and weld in straight pipe 2. Cut open rear muffler. It's best to cut open it from top - that way it won't be visible that it was opened - cosmetics wise 3. There will be a bunch of perforated pipes inside. Take a photo of them. Cut them all and throw away. Weld in straight pipes exactly repeating pattern of how perforated pipes were (I guess photo is not really needed it's not that complicated, but just in case if you will forget how pipes were initially placed inside the muffler) 4. Throw out steel wool fiber insulation and repack/replace it with new one (I guess old one can be reused if yours is relatively new and in good shape) |

I'm waiting for TheLastDetailNV to post his thoughts on his muffler delete mod, because I want to install a electric valve cutout before muffler - that way I can have normal quite mode and loud by the click of the button

I did the muffler delete yesterday and replaced it with two separate straight 2.5inch pipes. It sounded quite mean but cold starts weren't too pleasing and the drone between shifts were annoying. I will post a video of the cold start! Solme may have liked it but to me it was too much for a classy SAV. HOWEVER!!! I went back to my muffler shop today and had a non-resonated x-pipe installed and it's PERFECT so far. I can't comment on cold starts yet but regular driving is great with the shift pops being more pronounced but not overbearing in sport and sport+ mode. The shift pops or burble is virtually eliminated in comfort and eco pro mode. I have only been up to 55mph in 8th and experienced zero drone. The sound so far is a nice v8 rumble that only my gets loud when you go WOT otherwise it's a mellow tone that suitable for the vehicles character. I haven't noticed a loss in power but there is a definite weight savings with the muffler removal. I've invested $260 so far since I went twice to get work done. I will get some external and internal video later. At this point I am VERY happy! Before the X-pipe, I was not. I will have pics posted later. Jace |

Did you take pics? Where along the exhaust path did they weld in the x-pipe? With the muffler removed, the straight pipes were connected/welded to the exhaust tips?

I will take pics after work. I got it done on my lunch break. I took a quick peek and it seems to be welded in to the mid section. I will take a couple shots later. |
