I'm a new diesel owner, I have a '05 2500. I want to make it louder and was wondering if I cut the catalytic converter as well as the muffler out, put 4" stainless in place of those spots if I’m going to do any major problems to the truck? Let me know what you guys think and if I should try something else that would work.
Welcome! No, you won't have any issues. Lots of guys do it. If its too loud let me know. MBRP recently released a kit that is a direct bolt in replacement for the stock muffler and mounts their muffler in its place. Also, they offer Cat delete pipes already bent properly.
Any pics/prices for this setup, I would like to delete my cat with a bolt in kind of deal so if I need to put it back for an e-test I can swap it back in just for the test. waytogo
"Ya i was about to ask.....wouldnt that make you fail emisions?" .....only if you have emissions tests and it will be nice and loud, same truck i have
whos having emmisions tests on deisels?! yeh pretty well every single cummins dont have the factory exhaust no more. it seems thats just what you do when you get a cummins. buy it, drive it off the lot, drive to the muffler shop, Be loud!! thats my rule!
as far as i know only in certain states or cities and its not in central illinois that i know of as of yet thank god
Emissions? Yeah. lots!rotfl Sorry, couldn't help it!imp: You can find the products here. MBRP won't allow me to copy/paste pics from the site.
Colorado has emissions testing, at least in the cities. Moved from there 7 years ago. I don't think they sniff the diesels, though. They will check visually for emissions components like cats. I moved to Oregon where they require emissions in certain cities. Actually, I only know of them checking in the Portland area. They've talked about smog checking in my area but I hope they stay out of here. Check before you do it, though, because it would seem like a pain to swap in your cat every year. I've heard of guys in other forums failing their visual inspections and having to get reinspected with OE equipment.
If I remember right, Colorado has a visual for diesels every other year so swapping it out once every 2 years wouldn't be that big of a deal, I bought my 06 in 05 so I guess I will find out for sure this summer.
I don't think we have an emissions test in Virginia, but I'm going to look that up before do anything to my exhaust.
I just did mine on my 06. All i did was go to the parts store buy a 10ft piece of pipe. I cut the cat out and the muffler off the tail pipe, used 104in of the 10ft pipe and now I have a full free flow 4in exhaust.
wow, i didnt think anywhere but california did that. ha! well i know for sure texas doesnt, but i bet by 09, they will start wantin to do emmisions on all of them...
