I have no interest in downpipes on my X5 but have them on my M4 with the straight minicats and understand how these systems work. Simply adding support for the OP’s experience. Let us know what you hear from Lieb. Also do your own research, this isn’t new territory.

They’ve been quite helpful, I’ll post links to the x5m parts in the morning. They’ve assured me work, will find out soon.

Awesome. Look forward to the links for the parts for the F95. Thanks.

I have been told for many moons that this method can cause mixed results as many on here would attest to.

Sorry for the late response here. So yes, they did give me a heads up that it may or may not work, in which case they would need to tune it. Apparently my luck was high when they installed the spacer!

I appreciate the response. Yeah I have read up on this practice and it seems the stars have to align with each individual vehicle to get it to work. It's not that the spacer idea is a bad idea.

Apparently the device from LEIB-ENGINEERING works on the F95/F96 and I think I am going to give it a shot.

Catless Dp's sound great on that engine. We have F95 downpipes if anyone needs a set.

Possible to make a set with HJS cats?

No, sorry we do not have a catted version just yet.

I ran DPs for 20k miles and tbh, they were nothing but a headache. Without a tune, they are really pointless and mess up your A/F ratio. Car just doesn't run optimally.

I ran O2 spacers and that helped the CEL for awhile but eventually the CEL came on regularly. Performance gain is negligible without a tune and the smell is very present if you're not used that amount of hydrocarbon. They do sound AMAZING with the turbo whistle and all, but cold start is ridiculously loud and obnoxious.

Also be prepared for dealer to refuse warranty work and also if you lease, you could also void your contract due to modyfing the emissions system. I had several issues with my F95 that BMW refused work due to DPs. BMW is not messing around with modified cars now and even if you have a friendly dealer, their hands may be tied as well.

If you're not going all in with a tune and giving up your power train warranty altogether, I'd stay away from these on this car while under warranty. They do sound very good but the juice isn't worth the squeeze and I can say that from experience. YMMV

I drive mine since a year full decat... and full gpower exhaust never had problems with dealer or car.

I also have Racechip Black GTS with it and a device like LEIB-ENGINEERING so no CEL and no mess with A/F ratio.

The only problem there is cold start which is too noisy...everything else is better

Installed my catless DP's and used a set of O2 spacers. car was fine for a day and CEL came on today.
i dont mind it, but i lose the remote start function which in Houston is a must IMO.

OP can you please advise on what spacers your shop used?

[BLUEX5M]

Installed a full Akrapovic system a month ago and wow it has completely changed the sound of the car, i know its expensive but so was the X5M and issue free.
