take the cats off completely. dont know about hi flow cats.

what about the emissions? whats the way around that?

 

[eddie102870]

we dont get checked here, hi flows would have to be an improvement over stock. a lot of guys are usid the catless mids and swapping them out to get inspected if im not mistaken.

I have the high flows, and they seem to flow very well. You will not get the benefit of power vs no cats, but its definitely better then stock cats.

take both the cats off bro, then install a set of hi flow cats, just 2, will get you by on emmissions. Plus give a ton of hp probbly 10-15hp at the rear:rock:
You can get hi flos anywhere also

personally, i wanted catless for full power, but hi-flows for emissions, but didn't want the hassle of trying to separate those common slip joint/clamp systems after they've been on the truck for along time..... so, i flanged my mids with 3 bolt collector flanges for ease of removal......
