N55 catless exhaust with resonators

josega90 · 09-07-2014, 12:07 PM

Decided to post a quick video of the sound, since i was looking around for some videos of a similar setup before i did it and couldn't find one. Love the sound, it is extremely quiet when inside the car. zero rasp. I would like to hear the turbos a bit more though, so maybe a PE mod is coming soon.

It is a n55 with vrsf down pipe, two vibrant resonators, and the golf tee mod (or whatever its called).

sebasupreme · 01-04-2016, 07:56 PM

you removed the primary cats and installed the resonators correct?

dannyle27 · 01-04-2016, 08:09 PM

I did the same thing. Rasp is completely gone but still drones a little =/ I hate drone on automatic cars =(

what do you replace to install the resonators for on an N55? thinking of doing the same to eliminate rasp.

AX75F92 · 01-04-2016, 10:23 PM

RWD or ix? Also what model resonators? There are 2 part numbers that seem to be popular with the N54/55 crowd.

dannyle27 · 01-04-2016, 11:07 PM

Mine was rwd. Forward of the frame brace, there's a gap where I had the exhaust shop cut and weld two bottle type vibrant resonators in. I think they're vibrant 1792's.

mine's RWD also, did it eliminate the rasp?

EB89 · 01-13-2016, 01:16 AM

Do they make cold starts quieter?

I think it's generally accepted that DP with stock exhaust sounds good.

The rasp/drone problem is mostly on DP + PE or other aftermarket exhaust.

I went from stock to PE to DP+PE and then back to PE because of the rasp/drone. Didn't want to mess with resonators.

dannyle27 · 01-14-2016, 02:41 AM

Eliminated pretty much all the rasp. Quieted it down and less drone too but sounds sweet in sport mode with the Alpina flash. Still got a little drone when going up slope still, nothing major.

Here is mine, just VRSF downpipe and flap open
