I had a "different" style muffler system put on my 300SD a few weeks ago, it was done by Lentz, they did a straight pipe from where the resonators were, (they are gone now) back to the rear, where I had a "diesel truck muffler" (its huge) put on, and then a short piece of pipe and a chrome tip that points down at the street sticking out from under the bumper. My boost is lower also, on the freeway at 75 I only run about 7psi, used to be 10/maxed out at that speed. I also have more pickup from 70-110mph, it really moves!! And from a sitting start the car is way faster too. My mileage went up a couple mpg's. I've been getting very high milegae now that I have been taking a 55mph non freeway route for my commute. I haven't filled up yet, but I've gone 229 miles and the gauge is still touching 3/4 full!!! At 55-60mph on flat ground I run 2psi of boost or less. I can't wait till later this week when I need to fill it and I can find out my mileage! I am guessing 30-32! I've filled it from the 3/4 tank to the filler neck before, and it took about 7ish gallons, if that holds true right now, it'd mean I'm getting almost 32mpg. Quite an improvement from 23-24 at 75mph!
