I'll be getting an RB exhaust soon, and had two questions:

1. Will I be able to reverse up a set of rhino ramps, without having my front lip hit the floor? Stock body.

2. Would this give me enough space to do the install?

Any input is appreciated. Thanks.

1. yes and yes. if you're really worried put some two x fours under the front wheels to raise the nose a bit
2. yes

I have the MS front bumper and I have no problem with doing this.

One thing to be careful is if you reverse up the ramps, your wheels can PULL the ramps out of position. That's why I put them up snug against the 2" lip of my garage floor, so it can't move when I reverse on it.
