Been running a 3" exhaust system and never really like the rear exit, so out came the sawzall. Now she's a side exit after a few cuts to the pipe.

Nice!  I couldn't stand the trumpet looking exhaust that the Stinger duals used so I bought some bends and broke out the welder.

Thanks. Mine's the Stinger single kit and the last pipe had noticeable bend and did hang lower but no more.

The Stinger exhaust is a decent kit but it's far from bolt on. I had to work on every piece in order to get it to fit correctly.

I know what you mean. If I had a lift it would be a piece of cake but when she's on the ground it's a PITA lol.
There's only 1/2" of clearance to work with the 3" pipe going over the axle.

Those running the Stinger pipes, do you find it getting hit by the axle during bumps and such. 1/2" of clearance to the axle sounds like too small of a gap to not get hit during suspension travel.

I went with the duals but I had to cut and weld on every piece in order to get it to fit. I didn't have any issues going over the axle, plenty of room there but on the right side going around the gas tank is really tight and I had to cut the Y and spread it in order to clear the drive shaft. Stinger does say they the tubes are left long so you can trim them to fit, which is nice but I did more then trim.
I would not be comfortable with only 1/2" of clearance at the axle.

My bad guys, the 1/2 clearance is the side to side clearance from the frame rail to upper control arm on the diff, not much room there. There's plenty of clearance for the axle.

I am running the Stinger 3" exhaust single, but I did bring it to an exhaust shop to get it "massaged" a bit. I don't have that trumpet bend hanging low behind the rear axle and it is tucked pretty well around the gas tank.
No rubbing.

If I were to do it again......I would run the 3" exhaust up to the rear axle then convert to a 2.5" for the remaining. I believe the exhaust gases are cooled enough at that point especially without a cat and running less than 20 psig of boost. Then I could fit a panhard bar on the rear.
