I bought a 4inch kit with muffler and it arrived the other day. I installed it with the help of a frind in less than 3 hours. Everything in the kit fit perfectly and was clear and easy to follow the instructions. It was actually harder removing the old rotten exhaust#@$%!
It is much quieter than the straightpipe I had before, but still lets people know it's not a normal stock Cummins. In cab has absolutely NO drone which is a bonus for me especially on those long 8 hour towing trips.
I highly reccomend this kit especially considering the low price. Good Job Olee
