Is it a good idea to run 3" midpipe on NA?

I don't believe there is a big point to it. The exhaust will just pressurize at the cat back mufflers. If you go 3", then you have to get freer flowing cat back exhaust.

Not seeing it. How would he lose low end torque ? Most midpipe/hi flow cat installs I have seen give hp pretty much across the board or at least fatten mid range, if little hp on the top end.
If you have a resonator it will still be loud, as the cat. acted as a second resonator, but less then a straight testpipe. I had a hi-flow cat w/resonator & it was a little louder. Now I have a hi-flow cat w/o resonator & it is really quite a bit louder. I have heard one with midpipe & Corksport exhaust & thought my ears were going to bleed.
