So I ended up taking my 1er into a local shop over the weekend and did a muffler delete from the resonator back. Everything else still in tact.
Overall, I am extremely happy with it. Not terribly loud or ricey sounding, sounds just right. Will hold me over until I can have a nice V8 in my life. I'll post a clip this weekend coming up. I do have to take it back to the shop. There is an extremely annoying whistling noise that I get whenever I rev over 4500RPM, so I'm going to have them look over the welds and tips. Hopefully they can figure it out so I can actually redline it. |

I'm taking it back to the shop on Friday to have it looked over. Make sure it isn't a welding issue at all. Which I am assuming is the issue. Never heard anyone mention any sort of whistling issues that has gotten a muffler delete on their 128i. |

My worry is that for some reason it won’t sound as good, o have drone, or something since it’s technically not for the 128. But from everything I can tell the muffler part is the same? |

I just have a single pipe from the res that connects to dual/y pipe tips. Took it to the exhaust shop and the guy said my exhaust is whistling from the air hitting the y tips too fast and it's splitting it causing the whistle. Not sure what to do to remedy it, he told me to forward him a different set of tips which he will order and we can refit. So now I'm looking for some dual tips that aren't in the perfect y configuration, but more of an offset y like the stock muffler to see if it will fix the issue. Also would love to hear the sound of this set up you're running. |

I have had a muffler delete for about 6 months. I really liked it and was all smiles in the beginning now I want something a little more refined and aggressive. I think I can find them more deliberate sound if I put a performance muffler. I'm hoping to hear more burbles and pops which I already hear some in the higher RPMs with a muffler delete. Next paragraph I'm hoping to add a muffler I really don't want to spend the money of that 135i performance muffler but I might have to seeing that my only other option would be a universal exhaust muffler like a borla or MagnaFlow.
With the top down it sounds amazing. I could live with my muffler delayed and be happy but I'm also interested in a not too expensive performance muffler something in the $200 range. |

Just had the 135i PE installed. Didn't get much chance to play with it tonight. I'm taking her for a full shakedown in the canyons tomorrow, so I'll give some thoughts on it then.

I will note that I’ve had one issue. The exhaust has a small rattle when at idle. I’ve tried getting down under there while it’s running to see what it might be, and I think it’s either a hanger that’s not sitting right or it may be vibrating against the heat shield somehow. Weirdly, it only does the rattle at a warmed up idle RPM. The cold start, higher idle, doesn’t have any rattle. And if you add just a touch of gas when sitting there it goes away as well. I’m going to be taking it back to the guy who did it soon since he warranties his work for a year. |
