Mods to E550 Cab.




There is some info floating around here somewhere, but in short what I gather is if you go with deleting both sets of resonators, it is pretty darn loud and might drone in the cabin. With just the delete I have (and yes, straight pipe), it is actually pretty loud outside, and with windows closed, not invasive at all.
I think people say X-pipe is not quite as loud and there is some different opinions on whether it's good or bad for our turbo engines.
