Some members here used ultra quiet ones in the back, some drive in S do keep the RPM range higher than the dreaded 1500-2000RPM. One of my friend's F10 550 was droning similarly as he was always driving with the highest gear possible at the lowest RPM possible and he was not using Sport mode. Check your driving style. If it is similar to what I described, you'll probably get a slight drone.

Yes, and yes. The 1792's were too loud. It wouldn't have been too loud for a sports car that you drove for a few hours on weekends, but it was out-of-character for a German luxury SUV, especially given that it's my daily driver. I have no drone whatsoever.

Regarding cutting out the OE resonators just back of the downpipes, I'll be interested to hear how that affects the sound. Given that the right and left ones are different, you get a slightly different sound from each side and I suspect that this adds some complexity and depth to the overall sound. I wonder if you'll lose that complexity if you cut them out. I'm a musician and an audiophile, so timbre and complexity are important and noticeable to me. Keep us posted.

Yup, that's exactly what I would have gone for if I could - the price of getting those in Australia is nuts though so I've opted for a more generic setup. Once I get it installed I'll let everyone know how it goes (probably about 3-4 weeks time from now though). Below are the resonators I bought!

has anyone done the x-pipe and muffler delete AND installed catless downpipes? Wondering if I should just do the DPs with X-pipe and leave the exhaust stock for now and then cut them later if wanted.

It wasn't too expensive to do since the shop cut the muffler off and then welded new pipes to connect to the existing tail pipes. Plus they added the X-pipe, which I've heard on the forums reduces drone. |

Check the inside of that x-pipe, how the fabrication is done.
If inside is like the one I bought, it is very restrictive. (hopefully yours is not) Looked to me as if in a compromise to make production easier, the 4 tubes going into the X, are crimped at the end, inside the X. Unless they have improved on it, mine had openings into the x, that were crimped down to about 1.25" in diameter, if I remember correctly. Thus creating a way less smooth flow into and out of the X, and vortices possibly worsening the flow inside the X too. Since we have turbo charged engines, I'm guessing it affects us less than a NA car. But still not a good design. Now, I'm not trying to discourage you from using it, many people have used them with no complaints. I just didn't want to install something like that without fixing it first, so mine is still on a shelf in my garage. (or for sale to anyone interested) |

Took the plunge yesterday on my 50i XLine. Ended up keeping the stock tips as I didn't think quads would look right with the XLine styling. Loving the sound so far with just the muffler delete and Xpipe. Little bit of drone right around 1000rpm under load but I don't spend much time there anyways. Even got the girlfriend stamp of approval.
