135i N54 DP->Midpipe->Axleback Gaskets

[sparkyblue]

I recently purchased a used set of Berk Full DP Back Street exhaust from a fellow member off the forums. Their coming in Friday and I want to have everything I need to get them installed same day as they arrive.

My question is, what gaskets do you guys recommend I use? I know I want new ones, as gaskets are fairly cheap and exhaust leaks is something I dont want to deal with.

I've googled online and it looks like the OEM ones have this coating on them, while I've also found some after-market (Berk, Maddad) ones that seem to be just regular stainless steel.


I believe these are OEM:

Aftermarket:

What does everyone recommend?

EDIT:: I also know I'll need more than just one type, as there are the 2x DP->Midpipes & 1x Midpipes->Axleback connections. Where are the 2.5in & 3inch ones? Do I need any more?

I bought 2 2.5" copper gaskets (http://www.summitracing.com/parts/SCE-4200/) for the DP->MP connections. They stick out a little at the bolt corners but don't leak. I had previously used the ones that came with PLM DPs but they were leaking.

The MP->Axle back connection uses a donut gasket. I had to special order it from my dealer.

As long as your exhaust is setup like the stock exhaust those are the 3 gaskets.

Does this include all the connections from the the Dp->Mids->Axleback? Cause with the berk there's a connection 2x pipes from DP->Mids Part 1, then another connection from Mid Pt1 -> Mids Pt 2 which turns 2 pipes into 1, then there's lastly the 3in connection to the Axleback. Will I need gaskets for each connection?

No. The part numbers are only to install a N55 mid pipe.


Just use RealOEM.com to look up those other gaskets.

I've decided to purchase the two OEM gaskets from the DP's to the first section of the mid pipes. My question is what gaskets should I utilize for the Midpipe -> Midpipe Y Connection? And lastly the 3" Midpipe Y connection to the Axleback?

What makes this question difficult is the OEM N54/N55 midpipes are composed of a single set of pipes which mate to the axleback.

Did you end up needing an additional two gaskets for Midpipe pt1 > Midpipe pt2?

And what did you end up using for the donut gasket from Midpipe pt2 > axle

Thanks
