Are there any Hi-Flow Cats out there (or any cats in general), that would be able to fit on MAC Long Tube Headers and a MAC Off Road H-Pipe?

+1. But if u don't want to use any money, just ask ur mechanic to take the cats off ur old parts if u still have them(idk if u already put those parts on) and weld them to ur new set-up.

im sure you can use your old cats for a new set up with the longtubes, but call Pypes before you buy them, and ask about the catsand make sure you tell themyour car isa 6. I spoke with a pypes rep before i bought my setup, and asked about their hiflo cats, and they said to not buy them and thatits a waste of money unless you go deep into f/i later on. our cats flow at 300cfm, and the highflos go at 400cfm. they made a big difference on older mustangs cause their cats only flowed at about 180cfm. they can make a small difference however, on the newV8's. but i was told that the stock cats are plenty freeflowing four our cars.

Anyone have a link to exactly what I would need? I don't have the stock CATS anymore and without the stock CATS or any CATS in general, the car sounds like legit ***.

if you want to keep cats on your car, then you have to get hi flow cats because our stock cats are too big to fit with longtubes. i just got some mac hi flow cats to go with the mac lt's i will get in the future

Perfect. Where did you get the mac hi flow cats?
