The 911 guys have had some great luck with this, wondering how the F chassis do.

Well it's 15$ vs 125$. I still haven't had a CEL with my 15$ spacer yet after over 2k miles of driving. Choice is yours

I like your thinking.

OP, ever got a CEL yet?

Hope the answer is no because I want to do the same

Great tutorial! You saved me a lot of time. I didn't have the expansion tool so I spend majority of time trying to get the mid section on. I used the L spacer as well. However I am getting a CEL. Is there anything I am forgetting to do that's not mentioned in this tutorial?

Figured out the issue. The spacer DOES work. One of the o2 sensor pins was bent when I plugged bank 1 back in. It was bank 1 throwing the CEL.

Almost a year later and still no CEL? I don't have a b58 , I have a N26 but that's amazing

fb58 · 10-16-2018, 12:09 AM

grabbed one for my er downpipe. will keep thread posted.
EDIT: didnt fit :L

F30MGM · 11-28-2018, 09:57 PM

How's everyone's b58 ?

my CEL is still off 😁

vinzcast21 · 12-12-2018, 12:56 AM

What the hell why is the fuel indicator going up and down

JB4 turns the fuel gauge into a boost gauge under certain circumstances, like flooring it.

Martin30x · 01-11-2019, 06:49 AM

Guys how is your MPG now with downpipe fitted.

Had rs4, with dp and it takes much more petrol.

I am thinking of fitting dp in 540i but I am unsure now.

Btw: anyone with b58 have checked emission ? How much goes up.

Rs4 was over 4x times higher and you could smell fuel from exhaust.

DP will be arriving somewhere next week for 540i b58.

patofdzb · 01-14-2019, 03:08 PM

Wow, this makes me want to get a dp

CodyReviews · 03-08-2019, 11:39 AM

Did you only use the extension on one 02 sensor?

I have the CG Downpipe and was getting a code error reading when I checked through my jb4 and occasionally a light on the dash. O2 spacer made both go away.

EB340i · 03-08-2019, 07:03 PM

Most people probably don't care but what does the catless DP and O2 spacer do to the fuel economy?

heusing240i · 03-25-2019, 08:42 PM

For those who installed a vrsf, are you reusing the factory V-clamp?

Most end up re-using the factory clamp

Solid67 · 05-14-2019, 03:43 PM

How bad will the car smell with VSRF or any aftermarket DP and stock mid/axle back?

If properly installed, you won't notice any smell at all unless you're in bumper to bumper traffic on the highway with your windows down or are idling in your garage.

Did you need to use any extensions to give the ratchet space to turn when you were loosening the v-band clamp and the two small mounting nuts?

Brett530 · 06-10-2019, 02:03 PM

I posted some of my notes after doing my downpipe install as a supplement to this DIY (which was very helpful - Thanks!).
