      unfortunately my pics of exhaust build were crap.
      basically I didn't attempt top use the modified single outlet manifolds (X5? see garagistic site for ref.) . so Ive no idea if they would pass BAR.
      I wanted a 'stk' configuration 4>2 /2>1
      at heads : cut off flange end of stk header leaving as much 2bl wall header as possible to fab onto. used SS pipe
      reused stk 2 bolt flanges at ends, 'headers' end next to blk/trans joint. Stacked, not side by side. pointing down at 45*+- . this is tight but workable.
      Reused the stk 2>1 connector/pipe w/ reshaped pipe to end of headers.
      Then 21/2" back to Calif legal 540 walker cats w/ O2 sensors. dual 21/2" cat back to muffler.
      The BAR ref commented the headers had been modified but were representative/ close enough to what his diagrams showed.
      Your results may vary.
      I probably paid more for the exhaust system then all the rest of the swap.

        Did you just drill and tap a hole for the coolant sensors in the M62 pipe?

          No, the one we had already have the holes in it, they were just plugged.




          remove 8 and 9

          And the diagram on RealOEM is the older style

            Nice! I kinda figured that was possible but haven't had the waterpipe in front of me to check. You just made my swap easier, thanks!

                    Any pics of what you had to do with the headers? Ive thought this would be something that was possible. Congrats on doing it the right way

                      still no pictures, I am guessing you read the post above I wrote out a while back about how I went about the headers.

                      I'll be swapping the motor for an "upgraded" m60 in the next month or two... hopefully can take some pictures when the motor is out.

                        Have you got any pics of how you ran your coolant pipes using that rear accumulator pipe as i may go that way to make my swap easier and give me more clearance

                          This is great to see and all the details for it kept asking myself for longest if this could be legal

                              headers

                              So just to confirm. The only thing you left stock on your exhaust was the flanges?

                              The referee was ok with using all new exhaust piping?
                              Did you need to follow any guidelines like runner length and size, collector and cat location etc..?
                              Does it look close to the stock header design?

                              What can make the headers fail inspection?

                              Thanks for the info I'm in San Jose doing a s62 swap, trying to figure if i should custom fabricate or cut/bend/rotate my stock headers.

                                I'm working on the S62 swap as well. Pretty far away from getting it BAR'd at the moment but would definitely love to know what if any leeway the ref will give with the exhaust manifolds.
