Donaldson muffler

I am thinking about ordering the Donaldson muffler listed below. The Banks is too loud pulling my camper. I am wondering if the cfm flow rating is high enough to not cause high EGT problems with the TST box?

Sounds like the same one I have. I am very happy with it. EGT seems to have dropped with stock piping. I mounted it as far back as possible and if anything it is quieter than stock with the windows up doing 75. If I roll down the right side window (which I do all the time) I can bounce the sound off the a wall, Ford, Ricer, etc and it sounds great. My buddy heard it had to have one when we were in Vegas. Had it installed and we had a lot of fun cruising the strip in 3rd and 4th gear bouncing the mighty cummins sound off the casinos.

RTillery - What's the model/part number of the Donaldson you have?

M090544 is the Donaldson number I used. There is a long thread over on DTR. Do a search on Donaldson and you should be able to find it. I think the thread is 51" Nelson Muffler.

None with mine

Now problems with EGT's here. TST PMCR on 6 hp and 3 tqr all the time.
