I can't imagine any reason it would harm warranty at all. This should be safer than something like an aftermarket downpipe.
A few years back I had a '02 Audi TT - GT3076r, watermeth, inlet piping, downpipe, cams, etc. the whole shabang. The TTs muffler is about the size of the whole trunk. Went to a place down here in the hood and I think it was $100 for them to cut the muffler out, bend together a Y-pipe, and weld factory tips back on. They didn't speak any English but did a great job. Bueno! I know this is apples to oranges but after reading the whole thread and listening to clips mine sounded pretty similar. Cold idle was almost embarrassing, but the car had the power to back up the sound so I was OK with it. Partial throttle was the BEST. Nothing better than cruising next to one of those concrete highway barriers and letting it boost to a couple pounds. Really thwappy - combo of older VW R32, heavy cammed subi, and Infinity with exhaust. Really nice sound. Wide open though, it was 'pure chaos' as one buddy put it. You could really hear the note change when it was spiking to max boost. Still sounded nice, but in a way that was pure mayhem - it just wasn't as refined. Which I was fine with since the car was beginning to become a track-only setup. BTW drone was horrible. My poor dog would puke every time he rode in the car. I'm tempted to try this but IMO the F30 is too nice a car to have this sound. If it was a dedicated/partial time track setup I would consider it. But since this a sedan, is my daily, and doesn't make the power that goes with this sound I still think MPE is the best option down the road. But I do enjoy what y'all have done! Reminds me of my TT. :tear: RIP Last edited by munch520; 06-18-2014 at 08:05 AM.. |

Hey guys, I just got a muffler delete on my 428i M sport. Here is what I did:
I got the car last friday and a few days later, I went to the BMW parts center to purchase a 435i diffuser, about $80 with an employee discount, I got the hook up Today, I went to a muffler shop to see what they can do and he removed the stock muffler and made his own "setup", I know almost nothing about exhaust systems so I cannot go into too much detail. So now, I have a 435i style exhaust system on a 428i, and it looks pretty good to be honest. I haven't driven on the freeway yet to experience drone, but just by driving around town and starting the car, it is a little too loud and ricey for my taste. I don't know why, but whenever the car is in park or neutral, the sound is significantly louder. My daily commute consists of 80 percent freeway driving, so I usually like to keep the car in Eco-Pro mode. It seems whenever I am in Eco-Pro mode and let off the gas, the revs drop below 1,000 RPMs and the exhaust is basically silent, until I step on it again. I do have to admit though, when you're in sport mode and you use the paddles, it does sound quite good, especially with the blips and crackles between shifts. Also whenever driving around town, the drone is ridiculously loud when around 2500-3500 RPMs. Don't know if that is normal. One thing that I kept telling the guy was that I didn't want anything that was obnoxiously loud, and the only knowledge I have about exhaust systems is that mufflers are used to mute all of the noise the exhaust would normally make. When I asked him if there are any aftermarket mufflers I can get installed, he said it would not fit on the car since it was designed to only have the exhaust on one side rather than both. I don't know if that is BS but on the underside of the car, you can see the storage compartment that is in the trunk, where the spare tire would normally be, and it does take up quite a bit of space on the underside. I will post some videos of my setup tomorrow or latest Sunday. I do plan on going back and seeing if there is anything they can do to make the exhaust quieter, and I also would like to replace the tips he put on and make them look closer to the stock 435i tips because these ones are a little big. Thanks! P.S. I have the N26 engine |

Okay guys, after a while of trying to convince my parents to let me do a muffler delete (they're not fond of loud cars), I finally got permission. My plan is to to have the pipe cut with 3" stainless steel piping welded in joined at the end by an exhaust tips with a 3" inlet and two 3.5" outlets to have a little bit more aggressive look than the stock 328i tips. Is anybody certain that the dual 3.5" tips will fit? Thats still what I'm not sure of.

I'm thinking about installing a DOWNPIPE but I'm worried it'll be ridiculously loud

Gtman, is that a 428i with the 435 diffuser/435 pipe mod? I just ordered a 428 M Sport and can't decide between a delete or 435 muffler/diffuser.
Sounds awesome by the way. Last edited by geoff7877; 01-06-2015 at 06:56 AM.. |

oh it's basically to reduce lag...how many psi the dme is commanding the turbo to make under partial throttle. There for the wastegate is constantly adjusting...at least that's my understanding. |
