No frame issue. Very sturdy hangers. Flowmaster 50s pretty much under the seats. Some clearance issues with four people in going over speed bumps. A bit of scraping on mufflers but not horrible. Surprisingly no heat in cabin issue either, I believe the low restriction of the 50s allows exhaust to flow quickly.What kind of mufflers if any ? I'm thinking of doing that when I install my cutouts but don't know if I want them sticking that far out, any problems with clearance or banging off the frame?
