ACE headers is gone, Tomei is now in the car and all is right with the world.
ACE gains may be nice, but it was embarrassing to drive with how loud it was. I suggest you get a very quiet exhaust if that's the route you go.
I also have an R400 installed now which sounds perfect with the tomei UEL.
Wheels are still sitting until the CSG Spec Flex A's get here, and I'm contemplating if I want SPL or Verus for LCAs.
A very short exhaust video is on my instagram page until I make a more legit one. Stay tuned.
