Quiet muffler going on!
e36 m3 muffler-- the US muffler is the same as the euro (S50B32) muffler, other than necking down where it meets the mid pipes. The necked down portion is getting cut off. My thought here is that if it flow sufficiently for the 321hp, 7600 rpm S50B32, it shouldn't restrict the S54's 343hp/8000 rpm overly much (euro headers/cats/tune getting flashed on shortly).
For sure it's not as cool looking and going to be way more visible. But, shouldn't impair entry/exits more (muffler doesn't hang lower than the line between the tips and tires) and I want the car to be quiet
