HPF, can we get a new exterior cam video of the 135i resonated exhaust? From absolute cold startup to driving around...thx!
you will never get a direct comparison of the exhaust. I can tell you this is one of the louder exhaust and the CP-E midpipe to stock set up with OE DP's and OE muffler will sound like a prius compared to this.

The exhaust is being made so the prototype is not in HPF hands to make a video, but the 335i system may be done earlier. You can get a good idea from all the you tube videos, but still any video is off.
