Receiving my new car soon, a 340i Xdrive. I'm about to pull the trigger on EPH's package deal. Intake and JB4 won't be an issue to install. For those of you that have installed a downpipe (VRSF) on the B58...please chime in on tips.

Tools/Supplies:
8mm
13mm
17mm
T30 or T35
Copper High Temp Anti-seize
Swivels and extensions

From under the hood:
Unplug O2 sensor
Remove 2 bolts holding DP in place
Loosen the Vband clamp

From under the car:
DP to exhaust clamp
Bolts holding exhaust up

Allegedly the hardest part is slipping the catback clamp on the downpipe when installed. Removal of the right wheel might make life easier.

Does the above sound right? Do I need any gaskets? If so, part number/vendor? I'm not crazy about the JB4 auto code clearance. Can someone recommend an O2 spacer that works?

I recently had a friend of a friend install mine, it didn't take long, but we only ran into one issue. I have a 6MT Xdrive and also got the ER DP. The size of the DP was bigger where the cat ends and thus it was hitting some sort of brace. We shaved off some of the brace (very small amount) to keep it from contacting and vibrating. Painted over it as well to prevent rust. Other than that, everything else was fine.

Edit: sorry just noticed you were going with VRSF. But I believe they are both sized the same.

I've read a few threads that stated that the VRSF did not cause clearance issues with the Xdrive vehicles.

Looking at a CP DP.. just staring really and wondering about my warranty.
but it appears you would be safe to get a gasket and the turbo-DP clamp since its recommended by ISTA to replace when taken off.. gasket is $15 clamp double that
checkout realoem.com

Ok, I've heard hit or miss on the gasket. I'll get one just to be safe. The clamp is recommended to be replaced?

[insanecoder]

I'm eyeing one eventually and have it in my notes
the gasket is a no brainer ..if the gasket isnt able to reseal .. we got a problem
the clamp holds the dp to the turbo .. if it warps or the bolt strips we got a problem Houston.. cant put any DP on at all
yea those two I have noted to get
its possible to reuse both I suppose but I'll spend some $$$ to be safe cause Murphy has his sight set on me over the years.. Murphy seems to ALWAYS get me when I'm not prepared

Thanks!

[mike@x-ph.com]

Congrats!!

We will be sending you tracking numbers very soon

[Montego92]

I'm going to allow 1500 miles of break-in prior to installing the JB4 and downpipe. I'll do a full review and install thread (with pictures) once complete.

Now to find a meth kit!

Use the BMS meth kit if you are running the JB4

That's what I am currently looking at. The only problem seems to be acquiring methanol here in Deutschland.

Try looking for Methyl Hydrate.. Not sure there but around here most hardware stores will cary some form of that. Usually 99% methanol.

WILCO, thanks for the tip!

[Montego92]

In the case that the downpipe has clearance issues, what washers would be needed to make it fit?
