Hey guys. right now i have the stock pipe coming out of the 3rd cat into a cherry bomb xtreme but its just not the same as my 98 350 with true duals. was wondering if i can delete that third cat after the y pipe and get straight duals without throwing any codes....already got a blackbear tune. maybe he could help me with that? Will it get much louder or mess with my milage too much? Thanks for your input!

He can tune out cats, I would email him and ask.

Kewl. now if someone knows if this will make it a lot louder and if ill lose too much torque/gas milage??

Will be a bit louder and I would expect a performance/MPG gain, maybe not a ton, but it will be there.

im looking at long tube headers too, and i hear these pacesetters are the **** but I can't find a part number on their website for my truck. also i doubt they would bolt on to my stock y pipe/cats eh?

They will deffinately not bolt up to stock stuff from the manifolds back, they are longtubes so they come all the way down not just a little like stock, I am not sure if they make them for the NNBS's yet, best bet would be to call and ask.
