BMW 3-Series (E90 E92) Forum - View Single Post - PE Exhaust - N55 same as N54? Might have made stupid mistake.

Yeah... aware of the single DP. The N55 exhaust piping from the resonator back go from two to a single up to the DP.

The exhaust I bought is only axle back so I'm assuming the mufflers are likely identical.

I can use what I bought and just have the shop delete the resonator. PE exhaust doesn't go all the way up to the DP's. It starts beyond the secondary cats.

I'm thinking this will work for me. I'm currently straight-pip/muffler delete. These mufflers should be the same size and the rest is just removing the resonator.
