Ok so im considering letting the cat and dpf fall off the truck. Im now finding out that no one makes a bolt on exhaust kit for a reg cab long bed. So What fabracation needs to be done to make these kits fit the long bed?? I'm really just looking to get rid of the dpf, so another option is a test pipe to drop the dpf and keep everything else. Ofcourse either way I will need a programmer and egr blocker plate.

Any of u keep the stock exhaust and drop the dpf?? Pro's and cons???
I only tow a 4k trailer durring the week arould town. Once in a while I'll rent a skid steer or mini ex.

from what i understand, they are all the same you just have to cut off a length of the pipe compared to your truck. my MBRP had direction to cut off this and that if you had this or that. My truck is a 4 door long bed so i didnt have to cut anything

I have a regular cab long bed also, and you can make any exhaust fit with minor work. I have found the MBRP to be the best option. You just have to cut a little on the mid pipe and it will work great. If you have any questions let me know.

moved to exhaust.
