They're actually both excellent. The ETS with a resonator and dual rear muffler is probably just slightly less drone than the AWE resonated touring, but they'd be quite similar
It's in fact back ordered, we sell Maxton. If you're interested, I have a bunch of Aimgain Type 1 carbon front lips landing shortly, and I believe 1 APR left in-stock. Hit me up by DM if you'd like to explore other options!
