I figured I would start to compile some video's and put them all in one place for referance.
Here we go:
This car is an e92, running an X-Pipe with a dual exhaust setup (335 style) No resonator or 2nd cats, using a Flowmaster muffler (dont know the exact series he used, ill find out)
This is another car, Also an e92 running MMW Headers with No Muffler, No resonator, and No 2nd cats - Straight pipe!
Reving up -
Cold Start Idle:
Ill keep updating as more videos come in, and different setups come around
