Cranked the torsion bars, put flowmaster muffler on it. Running boards with bullet liner on them. Have to up date my picture tho!!!

Nice.

Nice truck! How many turns did you go on the torsion bars? How's the flowmaster sound? Any drone?

[alchrist3]

Thanks I went 5 complete turns and the flomaster 50 series hd sounds really good!

So how many threads are showing on your torsion bolts?

I had serious drone with my flowmaster with dual sides out. I finally went to have it removed and installed a Solo Performance Mach 44 muffler. Day and night. Now the neighbours don't give me that "look" if I let it idle too long in the early mornings.
