I got the 1141. I want my exhaust to be quieter and absolutely 0 drone and rasp, so the "ultra quiet" got me.

Haven't gotten them welded on yet. Most likely will in a week or so. I'll follow up.

I'd try and find YouTube videos. Otherwise, they are not horribly expensive. Install at a muffler shop might be around $100.00. Go for it. Please post a YouTube video when you are done.

Wondering what the inside of that OE resonator looks like? Real OEM calls it a center muffler... https://www.ebay.com/p/BMW-183075538...4113519&chn=ps Last edited by Bimmer_Engineer; 09-21-2018 at 10:55 AM.. |

Reviving an old thread because there are so much good information regarding x-pipe, resonators and secondary cats.
Can anyone confirm if the secondary cats compared to resonators do more to 1) dampen the noise and 2) eliminate more rasp/drone? I am thinking of putting in a 2.5" x-pipe in place of the OEM h-pipe resonator. I would like to keep the rasp and noise down, so would doing x-pipe only be a good idea? If secondary cats dampen more noise and block more rasp, doesn't make sense to eliminate them for resonators. Hope someone can explain. |

I'm trying to learn from your experience and do the same for my 335is. My idea right now is absolutely no rasp/smoke while adding more flow/performance so I can go Stage 2+. I will keep stock downpipes with HIGH FLOW RACE CATS replacing the stock cats, I assume this will help the rasp, as you explained the catted high-flow DPs helped your situation. Will add 2.5" x-pipe and keep stock 335is muffler without any mods to it. Did you try to figure out if secondary cats work better than 1792 resonators to cure rasp and dampen noise? |

Putting on 1792 resonators in place of secondary cats later this month. I was told to use OEM BMW Exhaust clamps which is more $ but a better way of fitment/attachment. Opinions on welding vs. clamping?

If you are talking about welding vs clamping the mufflers definitely clamp them. Why? When you clamp the mufflers it makes getting to the rear subframe (taking it out to redo the bushings & what not) or taking the rear differential out considerably easier. Otherwise, you have to drop the entire exhaust vs just unclamping & lowing the mufflers via a transmission jack. |

Weld the resonators and get a new mechanic.
