That's what I figured. And I haven't got used to it haha Iv been dealing with it for almost a year now. I'll probably just go with a custom exhaust out the side in front of the rear tires.

If it's real bad, try wrapping the piping with some heat tape/wrap to take the 'CLANG' out of it.

---edit---
Something like this.

The drivers side will hit the vent cap on the rear axle. Here is an easy fix we did: Jacked her up, took a torch and heated the pipe right where the cap hits. Took a 3lb hammer and a long 1/2" extension and beat it in just a bit. It just dented it in just enough to where it did not hit even on big bumps. After switching to the Eibach R2 system, with bump stops, we are just as low, but never hit anymore even when we bottom out hard.

We are set soft for daily driving. We are all the way minus on Compression and two clicks off full + on rebound. Been loving this setup. With the R2's you will just have to dent the 3" over axle pipe on the drivers side just a bit and it will clear. I also noticed that if you were to trim just a 1/2" of the front of the over axle pipe for the whole thing to slide forward 1/2" it would clear better as well. We kept our Magnaflow over axle pipes to the GT500 quads so we had the same pipe clank for a while.

That's about what I'm at only with a lil more rebound. And I think I'll try denting it in and if I don't like it or it doesn't work I'll probably just get a custom side exhaust
