No matter what muffler you have on it, you should keep it legal and safe by having the tailpipes exit out the back corners of the jeep. This keeps out exhaust gases. CJ's are bad for sucking exhaust into the cabin area even if the tailpipes come straight out the back, let alone under the wheels. It vortexes and sucks back in.
