why are you replacing your stock cats? you wont see much power gain from getting hi flow cats and if you have stock headers than that is going to be a real pain in the ass trying to get everything to fit right. If you are getting long tubes than that is a different story.

i'm not looking to get that big of a horsepower gain, i'm just trying to get my exhaust flowing good. i'm going to start with an slp loudmouth and hi-flo cats and after that i'm saving up for the longtubes. and i dont understand why the cats wouldnt fit on right just because it has stock headers.

becasue the stock cats have pipes coming on eaither side up th the head and down. so you would need to get it all welded and made it fit. trust me save the money wait till you are putting LT on than get a y pipe.
first notice the conection to the headers. I don't have the view of teh cat but there is about a 6 inch tube after the cat. you are not going to get jack from high flow. the cost is not worth it.
I mean we are talking like 3HP maybe.

yes, its does seem to rev nicer and in the uper band it really feels more powerful. couple it with an LS6 intake and you really free up the engine. LT= about 15 RWHP, LS6= about 15 RWHP (between) 4-6K on the RPM's

Stock cats flow good, no gain from aftermarket cats.
