Downpipe clamp question...

Brey335i · 11-24-2010, 10:35 AM

I've been trying to install my new downpipes since last night, but I don't seem to be able to get the clamp to close around the downpipe and turbo. I made sure everything sits flush. Any help?

And yes, I tried turning it and rotating

Yes, this is the hardest part. It takes FOREVER, you just have to keep adjusting it and it will eventually fit. My brother had to it.

if you remember how it was oriented "clocked" from the factory, thats the easiest and best way to position it back on, plus if you are running vk or raceland, its very possible the flange isnt round, or the flange itself is too thick or misshapen.

I have the new AA 3" pipes... I just cannot seem to make it fit

Man I feel for you with this install even though I had no problem getting on the clamps at all, but the overall install was just a PITA...Good luck...Kevin gave me a good tip which was to install the rear turbo clamp, position your body instead of head first underneath the car, put your legs towards the rear of the car and face the opposite direction that you were initially taking off the dps

Its the trickiest part of the job. You're the first guy from the GB to install these so very anxiously awaiting the feedback

I think everybody pretty much covered it on the advice side of things. The first time you do it is a real #@$%*.

Feedback on downpipes: so far so good

feedback on BMW's method of attaching the downpipes to the turbos: $%#@&*^%(#%#

one of the reasons i'll never want to install another set of downpipes ever again. i got one of the clamps on relatively easy...but the other was a real bitch.

with a lift would this make this part of install simpler?

deffinately the hardest part of the install...

I had lots of practice on some DP's that didn't fit. Ar pipes are the easiest to mouth up and clamp though.. thats good.

take a break... get you some beers, and spend 5 min trying to get it on, then take a break, then go back, then take a break.

I like to leave the clamp as close to in place as I can get it, then move the mouth of the pipe into place. Keep handle of the ends that go together, and then jiggle the pipe. Keep squeezing those ends together, rotate the pipe till it clicks in place. Its a great feeling when you here that click sound. The good new also is... the more snug that clamp is, the less likely you will have a leak later on. Lift would help a lot, although I did mine on ramps... You want to rotate the clamp some too. One hand on the clamp squeezing the ends togther...one hand on the pipe holding it up so that mouth and the turbo meet flush. Your arms will get tired...... my back was black and blue for a week from laying on it with my hands up.

You will have a whole new relationship with your car when your done too. She will love you back for the attention.

did you take all bolt completely off from the V-band clamp?

Yes from all the install I have seen the bolt was off because you need to spread the V clamp

that's where I was getting at. I was wondering if he took the bolt all the way off so that he can spread the v-clamp.

Brey335i · 11-25-2010, 04:15 PM

You have to take the bolt off to be able to get the clamp off.

So progress has been made: I managed to get both clamps on and get the downpipes hooked up to the exhaust out back. It's incredibly tight down there (lol that's what she said)... but it fits barely.

Drove around for a while, the exhaust was a bit louder and growled more. Very sexy...

then something happened haha. It's now incredibly loud and I can hear a fast ticking noise when giving gas... my guess is that the clamp wasn't tightened enough or something... and now it's leaking a bit.

No matter, I will put the car back up tomorrow (thanksgiving making me too busy today) and see what is up.

On a more positive note: pipes seem to fit well and the car feels amazing to drive (until I started sounding like a 70's pickup truck that is...)

All problems I have been having have been due to faulty install. I'll post up my impressions when I get it fixed
