I've read somewhere that they have better 'flow'.

I already have the '07 catless up-pipe. Would it be in my best interest to pick these up, have them port & polished (and coating?) and installed? I'm ramping up to have my vf43 installed, and am trying to find lil things here and there that will make my tune that much "easier" on my ego. :)

:woohoo:

yes, but def do a port and polish. Pnp's sti exhaust mani's flow great. I made 430/360 on them when i was still on my dom4 so they hold up to big power as well.
