Every turbo diesel needs to breathe so in this video we make a custom catless downpipe for my 2005 Mercedes E320 CDI. We also do a before and after sound clip and 0-60 MPH to measure the performance gain of removing a gigantic restriction in the exhaust. This downpipe should work even better with the larger turbo that's on its way and once we increase boost even more.

    Hello I have a 1987 mercedes 300d turbo diesel. I believe my cat is bad and I'm thinking about removing it and busting the core out and bolting it back on.
    Will this set off the check engine light. It shouldn't hurt the way it runs considering its not electronically controlled correct. Any advice or suggestions would be greatly appreciated. Thank you.

    Curious about how you tune it without the downpipe and exhaust modifications.
    I have an ML 320 CDI and e320 cdi.
    I have a juice box on the SUV, which is quite nice… But… It looks like there’s more to be had!

    Personally to me the exhaust note sounds less but turbo greater. Would rather some engine note personally. Off to watch the next episode in this series thanks Alex
