So I hear everyone saying that the sound of the Eisenmann race exhaust changes a great deal over the course of the five hundred mile break in, so I made a video of my new system with 10 miles on, and once break in is over I'll make a comparison.

wow sounds awesome! It has that deep tone to it. Are you planning on getting a cold air intake?

we'll see, I think the next step is the sr pipes. I'm getting blacklines and brex white rings soon as well.
