how much boost r u running and what r all your mods

ive heard high flow cats are 96% of a straight pipe....not sure how true that really is. To get the absolute, 100% MOST power out of ur new turbos, then yes a midpipe would be worth it. You also have to worry about spiking as well. But for most applications outside of insane street rockets built to the hilt, you wont miss much with ur hi-flo cat.

I am running 16-17 PSI.

umm, yes, you'll notice a big boost

get a lightweight flywheel and midpipe, it's like a kick in the ***

above 6k rpm it's night and day with a mp

then again, you have to ask yourself how much time you really spend above 6k

the main reason I went with a mp, aside from top end power, was because I like to shoot flames

and I also wanted to strip all the emissions related crap off my car

ok thats about were the stage 3s work best aroung 18 psi (non-seq?). Midpipe will add noticable power specially top end but I hate the smell and the noise. Hope you dont have N1 duals cause its harley loud with midpipe.

That dyno is garbage. Do not use it for any sort of comparison purposes.
