Bigblock is in line from what I've seen...My car laid down 321/331 stock, and when I added longtubes, ory, and a Hooker catback, it only went to 336/347. Since he already has a Borla catback, only gaining ~10rw is quite possible, if not most likely.
Now if you get a tune, then you will see the potential of your car begin to shine! After a tune, and the addition of my own ported TB, my car's numbers jumped to 354/373!

IMO difference in hi flo cats and no cats is only a few hp. I've seen some applications benifit from the cats over none.
I think the preference in no cats or hi flo cats all has to do with sound over performance. Myself I need cats for visual inspection. Not to say on my next y pipe the cats will be flanged and so wont a pair of dumps!! LOL
Mod wise look at my sig, and I am at 375 hp. My Y pipe is an utter engineering failure and would not be suprised if it finds itself on Modern Marvels Engineering Disasters 18!! According to my tuner, Once I get my exhaust squared away and he can touch up the tune, there is no reason I will not see over 400 hp.

Well Im not Joking...
Thank you.. Briancws6 - you can justify this as well..
To Ok. I have my magazine at home GM Performance January 2007 (I think?? its the one where Gm's Test Car -All Black z-28 is on- they put the 427 N/A motor in it ) Well- My car is in the back of that magazine. Not to brang, and im not- but by far, i have one of the baddest exhaust systems out, Stainless Works did all the work- all stainless 1 3/4 inch headers, 3 1/2 inch main pipe goes all the way up over the rear, then splits off the stainless muffler, They did the dyno and it added about 25 extra horse, 15-16rwhp.. (That was before the Procharger) I was giving ya the benefit of the doubt.. If you around northern Ohio- they (stainless works) will do it for ya- in it was 3200 dollars in exhaust work, not cheep, but done right, and very nice.. GL
