Welcome... I'm going cat-less also as soon as I get a set of gt500 mufflers.. but I am keeping the stock H mid pipe, multiple tests on dynos show 3 HP average more for the X pipe but I will leave that on the table for the sound the H pipe provide. (X pipe is more European raspy) some people like that, I like the boat under water exhaust sound.. so stock mids will remove 3-5 HP over aftermarket IF you just remove the cats , what's the cheapest mid pipe? $230.00? Nah... as for tune... I like bama however... gear headz does good stuff and I don't know the other local tuners but I believe in supporting local ...
