That sounds so good, it's causing me to second guess myself on getting the lm2 catback. Except that I won't be doin longtubes so the mac probably won't sound as good maybe?
Before I put the longtubes on, it was really deep and not as loud up top. Until i did that video, I was missing how deep it was before I did the longtubes. I was in the same boat as you with the LM2's before i ran across a good deal on the MAC.
