02 cummins, straight pipe?
I just picked up an 02 cummins 4x4. My first diesel, by the way(yay!!). I was wondering about running straight pipe. I dont know that much about diesels and what you can or cant do. Can i get rid of the cat. converter and the muffler w/o check engine light coming on? Will it be too loud and annoying? Driveability? How much to run a straight pipe? I dont want to spend $600 for a 10 foot piece of bent aluminum pipe. Thanks for any help

on my old 02 i acquired ~62" of straight aluminumized 3" OD tubing (flared to 3" ID on both sides). no catalytic converter on the 02, just a resonator and muffler. cut both of those off and install the 62" pipe. all done. loud is determined by the individual but most people will hear you for a few blocks before they see you when straight piped...i liked it and most others thought i was a school bus.

Me and my friend did it for his moms truck(1st Gen). It was 37 bucks for a shop to do it and with a turndown tip you cant even hear it with the windows up. BTW your truck doesent have a cat, it has a resonator. It also got the truck 3 more MPGs!!!

I straight piped my 02 cummins. It's nice and loud and you'll be wearing one of these when you go under a tunnel, bridge or drive by a wall

iv run straight pipe on factory exhaust and loved it. iv run a 4" downpipe with 5 feet of 5" and liked it but would have liked it better had it gone all the way out. and i have run the 4" downpipe by itself.. that was the loudest... all sounded good! but then i like the sound of a tractor!!! i meant that’s where our engines originally were!!!

I ran a Genos muffler eliminator on the stock exhaust on my 01. Just installed 4" MBRP without the muffler and love it!!
BTW...anyone looking to buy the eliminator kit? I saved it when we cut off the stock system.
