Size is ok, fit is ok, power is ok, quality is what you're giving up. Pacesetters have a habit of rusting quickly because they are not stainless steel.

I have pacesetters fit like a glove easy...power not bad....13.14 at 107.92 full bolt on car with port and poilsh tb baseline tune just some timing and torque management removed
1 season with the pacesetters on a spring/summer/fall driver, no problems. I have the low end ones and the paint came off almost instantly but I plan to cover them black again this winter.
Pushing 411rwhp/384Tq through them. Had hi flow cats welded into the mid-pipes and actually went back to the stock cat back exhaust (w/ H-pipe modification) after having them connected to a Corsa. Tight fit after we welded the cats into the mids but fit good with both the Corsa and stock exhaust.
I'd love to have a better header but then I'd be running headers and a CAI with about 320rwhp and wouldn't have the heads and cam because of the cost.
