DP to Mid-pipe Leak

TOS_335i · 06-09-2012, 04:58 PM

Has anyone had to double gasket the DP to mid-pipe connection to get it to seal? The flanges are hitting and I still have a slight exhaust leak... Is there a thicker gasket out there? I have cp-e DPs for what it's worth

Are you reusing the gaskets or are these brand new?

TOS_335i · 06-09-2012, 06:34 PM

New ones...

Are the flanges aligned perfectly? That is the first connection you should align. Then, tighten the turbo-to-DP V-band clamps and everything else.

Yeah, they look completely flush... Just can't get them to seal completely. I brought the car to a shop and they said that they couldn't make it any tighter either...

Buy a 2nd set of gaskets, might help close up that gap between the pipes

I have a leak on one of my dps currently as well. I figured it was a bad gasket...perhaps I need to double gasket mine as well to complete the seal. tightening didn't work for me either.
