Yes, quads were removed. However, prior to the lowering springs I didn't have to remove them. Flipping them worked. They were worn out though...so I just pulled them off.
With the lowering springs on it, I'm not sure if they would've worked or not if they were flipped as I never tried it.
The tailpipes are pretty close too, bout 1/2" on each side. I plan to get wider tires when these are worn, and I'll possibly have to massage the pipes.
Thanks for the compliments.
