cutout on a stock exhaust...probably 10-15hp
hard to say what the gains would be on the juice.
if you really want to take advantage of the cutout, have a shop put some 3" pipe from the Ypipe back to the cutout...then run the stock 2.75" pipe out to the muffler.
that way when you open the C/O you'll have all advantages of a 3" exhuast

I have dual 3" cutouts right at my header collectors.... I LOVE this setup, especially on the 150 shot. you can really tell it opens things up, I can only imagine the gains would be better still with stock exhaust. for the bottle a cutout is the only way to go IMO

Because I paid only $250 for the cutouts and catbacks are 600+?

I gained 60hp by opening up the cutout verses going through flowmaster exhaust. Sounds ridiculous but the dyno doesn't lie no other changes were made just opening the cutout

It's going to depend upon your setup. If you have a big cam and are flowing a ton of air, it'll of course help more than someone with a little cam and not moving as much air. Then there's the oddball cars that respond differently from other cars for no apparent reason.
So just like everything else, there's no set gains.

i used them once on a n/a h/c/i car i did, and it slowed the car down. sounds good open, but killed way to much lowend-midrange torque. back pressure(the right amount)is a good thing sometime. but like everything else, depends on the combo.

Never had my old car, a 95 Z28 M6 dynoed, but it was basically stock and I went from 9.0's in the 1/8th to 8.80s on average...about a .15ish drop in ET. For 33 bucks shipped it was worth it.
