I like my RH cage, even if it does bow the center of the dash a bit.
I think some of the dash bowing issues are install problems.
When you install the bar across the dash, raising or lowering it just a little tiny bit on the side tubes it mounts to will make a big difference in how hard you 'squeeze' the dash.
Theres also the issue some people have with the doors rubbing the side plates, but I never had that problem.
I really don't understand making a choice between these two as your next mod?
The RH is a chunk of change and a safety item.
Exhaust - even if you blow a bunch of money on a bolt on deal that goes in the stock location, it's just a noise thing. Zero to very little performance gain.
For exhaust, it makes a lot more sense to just buy a muffler, do 2 quick cuts and slip it in under the drivers seat. It's protected there, sounds better and even if you buy a kit to do it, it's under $350, if you buy the muffler and clamps (all you really need) it's under $100
I think I have $85 and 20 minutes in relocating a Flowmaster Super 44 under the seat.
