Nice dude. I was considering the q300 if my current catback is too loud with the UEL I ordered. One thing that bothered me is the q300 is mass produced in Taiwan and Tig Welded by Robot.
I prefer American Craftsmanship and using humans to weld. Lol. Quality control is much better when exhausts aren't mass produced.
I did see the q300 video with the UEL. Sounds great
