The power gains from swapping from A to B? Or from stock to A or stock to B?

i think he means the difference between the two, i would guess the non catted y with the hooker, loudmouths are supposedly bad flowing

There might be a difference in like 5 hp between the two, these catted y pipes have aftermarket cats that flow real nice.

ummm...the LMs are one of the best flowing exhausts there is. have you ever seen one...you can see strait through them! but i think the ORY w/ hooker will sound better and give you slightly more power.

You will probably see more peak horsepower with the Off-road y.

With the catted y you will probably see and definately feel more low to mid-range torque.

I have the FLP headers so I can switch from a catted y-pipe to an off-road y-pipe in about 30 minutes. I definately prefer the catted y-pipe. The car sounds MUCH better and feels stronger when driving around on the street.

I have a borla cat-back with a wide-open plate so I essentially have a cut-out which exits at the rear through the tips. When I take the cats out, I have to put one of the plates in the exhaust to quiet it down and get rid of the rasp.

Also, with the catted y-pipe, you can pass inspections easier and you don't get the gas smell in your car when you have the windows down.
