I have a 93 xj it had a 4.5 inch lift from rustys offroad I replaced the entire exhaust from the motor back with apn header flowmaster catback exhaust I bought a downpipe for a 96 and up because it was bigger 2.5inch I looked under my jeep noticed dents in the downpipe and the o2 sensor is slightly smashed it happens when the front suspension flexes out I know one answer is more lift but I want to keep this a low center gravity jeep and its my daily driver anyone else have problems with this mod any help or suggestions would be appreciated

Is there a way I can do that without removing the coil springs?

Many of us are running these inside our coils, http://www.jegs.com/p/Prothane/Prothane-Coil-Spring-Inserts/762178/10002/-1 your uptravel can be tuned by trimming rings off. Im running 6 rings with 6" of lift. Search for the prothane coil bumpstop thread for more details

no mounting. it simply floats inside the coils.

Are you sure your axle is centered? If you have an adjustable track bar, shorten it a bit to pull the axle toward the drivers side.

Check engine mounts, check if axle is centered.

You can use hockey pucks as bump stops. I used them with the Right stuff sealant (what I had on hand) to hold them down. That was several years ago.
