Cat delete question???

[montytm26]

Hey guys. Just got my Spartan installed yesterday and the DPF delete pipe I got with it. First off, WOW!! Couldn't believe the difference. Still getting used to the shifting, but that's ok. My question is, Is there any BIG difference between both the CAT/DPF delete as opposed to just the DPF? Has anyone actually run both scenarios that could reply?

Yes I have ran both. I ran the dpf delete for about 30,000 miles and the dpf/cat delete for the last 20,000 miles and I did NOT notice any difference in power or the amount of smoke. The dpf/cat delete is louder with more hair dryer/jet sound. This is with the stock dpf back exhaust.

just curious, did you notice any difference in your exhaust temps with the cat v/s without? i lopped them both from the get go but, i know on my 6.0 the temps dropped 200-300 degrees on a hard run after the "kitty jumped off the truck and ran away"
