Does anybody know the Hg (back pressure) is on a stock 6/92 MCI muffler is.
You could measure the muffler then go to Donaldson and find the duplicate muffler and then look it up on their site. On a 6V-92TA, if you have a 5" system, most mufflers will do the job. 8V-92TA's you have to be careful to get a free flowing muffler since the 8V flows so much more air then the 6V. Donaldson makes turbo muffs that are free flowing and put out a bit more sound then the stock stuffed up mufflers that come on a bus. I have the 5" same side in and out oval muffler on mine, and it sounds very nice going under a bridge (have an up exhaust). Good Luck, TomC
