M Performance exhaust and catless DP sound?

avantix · 11-15-2013, 03:48 PM

Hi guys does anyone know how an M Performance exhaust will sound with catless downpipe on the N55 engine? Thinking of doing it and would like some opinions.

Thanks

I second this. I've heard the MPE with a DP and a JB4..........it sounded beautiful.

I will know in a few hours what it sounds like. Both are being installed as we speak.

That sounds really good. Do you have any issues with smell?

Car sounds insane and very agressive with M performance exhaust and ER catless and it will only get better as the exhaust breaks in. Turbo spools much faster and you can definitely hear it more. I will post a clip over the weekend of a cold startup and drive by.

how long did it take to do? and how much did it cost?...asking all this, bc I have the MPE on my 435...and I'm not all that happy-- I want it louder/more beasty!

M-terkait · 11-22-2013, 09:33 AM

maybe you need the MPPK+DP for better sound

Cateye · 11-22-2013, 10:02 AM

I have MPE with sedox 200 cell cat dp, together with Hartge piggy.. sounds much louder than before dp...
Cold start is damn loud but only for abt 1min 15sec..
BTW mine is m135. Same N55 engine... I got afe intake too

Downpipe is a breeze on the N55 compared to N54. Takes an hour to take off the old one and put on the new one. Maybe 1.5 hrs for a mechanic doing it the first time. All depending on the hourly rate they charge you. Less than $100 for sure

Yes on startup in the morning it's very loud then quiets down substantiall on mine too.

Sp82 · 11-22-2013, 10:53 AM

then what difference does this make?...bc mine right now with stock dp...and MPE...its loud on cold start/morning...then about 30 seconds later its quiet.

The sound difference is quite noticeable. It amplifies the sound properties and "note" of the M exhaust since there is no restriction from the catalytic converter built into the stock downpipe. Also, the turbo will spool faster. Lastly there are some nominal performance gains, not sure but I imagine maybe 20 or so HP.

Here is an old video of mine with the MPE and ER Catless downpipe.
