Dumb and off-topic question - Do all N55 downpipes sound the same?
Cant seem to find a decisive answer after some searching ...
I have the stock exhaust, and cant say Im in love with the sound of the DP. After some time, it might grow on me though.
The stock DP sounded better (throaty), but I only listened to my new catless DP (raspy) for a few seconds in my closed garage (it was -30*C/-22*F outside)...
Edit: looks like I might need resonators to solve the catless DP rasp ... Either VibrantPErformance 1792 or Aero AR25 ...
