    Perfect fit, night and day difference. If you plan on doing this to an early model LML get your torch and PB Blaster ready. You're going to need them!

    This job is a PIA but totally worth it. Took me 10 hours including exhaust, and changing fuel filter and oil.

    The deviant egr cooler delete is great....just had a couple of minor issues with taking the egr cooler off. The L Shaped hose that comes with it has more than enough length. Had to do a lot of trimming. The up pipe is a must but if you do this delete you should go ahead and get a aftermarket downpipe
