What power gains can I expect if I go w/Longtubes?

I'm kind of at the same place that Stang_ROTY is. I've got about 345 rwhp/375ft-lbs of torque and am trying to figure out how to bump it up some. I currently have a 70mm TB and am thinking of getting a 75mm. Long tubes would be nice, but probably too loud for everyday use and PKRWUD tells me that speed bumps are a pain. My car is lowered, too, so I can only imagine how bad it would get.

If you're pulling the engine, you may be better off getting your intake and heads extrude honed.

Yep, my car is NOT lowered, and clearence would still be an issue, my friend throws sparks all the time with his, then again we live around some bumpy roads.
