EROD manifolds and cats?

[Dubnova]

Hey guys, Can anybody tell me if the exhaust manifolds and cats that's come with the GMPP E-ROD will fit in the frame (65C10) with the CPP LS kit. I kinda went off the deep end a bought a E-ROD Connect and Cruise setup from Pace Performance and after the fact I am wondering if the exhaust will have to be changed. I bet moving the cats around (TUNE) is a little different with the 4 O2's. I have the CPP/ Doug Thorley headers that came with the CPP package but, I want this truck to be dead quite and not stink like old nasty gas (Cats and Evap). That's why I went with the E-Rod and not the 525 hp stuff
