BMW 340i B58 VRSF Downpipe DIY :) NO CEL ;) *SOUND CLIP* Stock exhaust+Catless DP
Hi fellow b58 ppls. Im pretty sure most of yall dont want to spend 400$ at a shop to install the your brand new downpipes so Im making a DIY for you all, It took me 3 hours or so to put it in because ive never done a downpipe in my life before, but I will show you a trick later that will save you a LOT of time. I went through the headache but now I will save you time ;D
Needed tools: 1x Ratchet 1x 14mm 1x 13mm 1x Pipe expanding tool 3" 22mm Wrench 1x Anti Seize Paste 1x 8mm socket 1x pick tool Step 1 Put car on Jack Stands Step 2remove airbox ofc Step 3 Remove Under tray cover STep 4 Remove Oxygen Sensor Wires. This one is a little tricky, unplugging them is easy, just twist the locking part press down and pull out but to get the o2 sensor wire off the plastic wire box cover thingy use a 90 degree pick tool and press the locking tab down and wiggle it out ] Step 5 Unbolt DP to midpipe (IIRC it was a 13mm) STep 6 unbolt downpipe to turbo(Bolt is under the turbo using a V-Clamp Feel for it when the engine is cool to touch(IIRC its a 13mm socket use a deep socket) Step 7 With the DP and everything disconnected there is 2 nuts holding the DP to the car(Sorry i forgot to take picture, but just look down and reach for the two 14mm nuts and loosen them, at this point your DP is probably stuck to your midpipe still so all you have to do is wiggle the darn thing out Step 8 Once youve gotten the DP off the car remove the two pre cat and post cat O2 Sensors with a 22mm wrench Step 9 Stick a small amount of anti seize paste on the threads so its not a PItA to get off later down the road if you have to. Step 10 ****** NO CEL TRICK******* Errr so for you "Track and Offroad only/Not legal for street" people errr all you have to do is buy a 90 degree o2 sensor extension and place it in this orientation which can be found here: https://www.amazon.com/Degree-Angled.../dp/B00B1U6I54 *********NOTE THIS IS FOR OFF ROAD USE ONLY NOT LEGAL FOR STREET USAGE*********: lol: OH and yes you will still pass inspection if its OBD2 only Step 11 *********MAJOR KEY This single handed took me two hours of anguish because i did not use the pipe expansion tool. the down pipe would not fit nicely and now my neck hurts like crap because of this ******** With the Pipe expanding tool make the inlet on the midpipe bigger like this. You can rent one of these @ autozone or oreilly for FREE STep 12 Start putting DP back where old one was Step 13 Line up the DP to turbo and put the v clamp back on and tighten the clamp on the midpipe as well as bolting the midpipe nut back on to hold it in place(I forgot to mention removing that earlier but im pretty sure that is self explanatory. Step 14 Plug in O2 Sensors Step 15 Put undertray cover back on Step 16 Close hood jack the car down GO TAKE A SHOWER because i know at this point you probably have black all over yourself for whatever reason. And we dont want you dirtying the inside of your nice new BMW now would we? Step 17 Go do some 0-60 pulls and let me know how it goes Sound clip per request:

And thanks for the thanks guys means a lot, I just know that when i was younger I relied on DIYs back on e46fanatics to fix up my old 328i. Now that I have extension knowledge of cars and whatnot I see this as my way of giving back to the car community

Thats awesome. I am hoping I have the same luck. Not sure if it is worth just getting an L spacer like yours, or getting something like this
http://www.fabspeed.com/universal-o2...tic-converter/ The 911 guys have had some great luck with this, wondering how the F chassis do. |
