Sorry from the start of this sounds dumb guys but I figured ask. I'm just now looking at different header systems as I would like long tubes and an x-pipe but want to keep my stock NPP cat backs.
What size do I need to connect it all to the stock cat-back? I'm mainly looking at Borla options. Any info would help me as I'm new to modding my C7.

Texas Speed longtubes if you want a bargain and still not have a piece of crap. I currently run TSP.
Forget the rest.
1 7/8 is best all around size.

Great advise from Higgs Boson.. Personally, I use the 1 7/8" American Racing Long Tube Headers on my C7 with my NPP as well. Sounds wonderful!

Thanks. So those will run all the way back to the stock cat backs?

I have always heard that 1+3/4 was the best size if you don't do anything more than headers and COA.If you might want to do A cam,supercharger and other thinks then go with 1+7/8.
I'm just going by what I read on the forum.

I would call up ARH and discuss your situation/goals with them, because they make both 1-3/4" and 1-7/8" full length headers. For me, since I'm a hopeless Torque addict, I'd go for the 1-3/4".

I will easily put tsp headers against any header available. The extra long primaries make awesome torque gains that's hard to pass up compared to typical long tube designs. The 17/8" versions are in stock and 2" is in final stage of development!
