The cat is in your downpipe. You'll end up removing the crossmember to get it off.

Well, it isnt as big as a restriction as the NOX and DPF but what the long term effect is unknown. The only reason I see keeping it is if you want to make a quick cahnge back to the stock system without messing with the downpipe.

I noticed quite an increase in the exhaust sound, especially the ebrake sound. It was nearly unnoticable with everything on. Then slightly noticed with DPF delete. With TBE it sound awesome. Warming up with the Ebrake sounds like a jet engine on a cold morning.
Hitting the Ebrake on a downhill offramp with the soundw all is neat.

Looking for info and tips. I have a stock '07 5.9l and am wanting to make the following changes. 1) gut torque tube 2) add AFE stage 2 air intake 3) add AFE intake manifold and 4) delete cat and muffler and add 4 inch straight. I know it will be loud, however my concerns are will I get some type of an error or cause any problems with the motor itself? Thanks for the anticipated input fellas.
