Got it man, hope to look into this soon. Looking forward to getting these lt's installed.

Well, my LG's arrived, now just have to get a day off to install. Can't wait. Kind of wondering if I should have purchased high flow cats. Question, if I install without cats, get tuned, and decide to install cats later, will I have to tune again?thanks.

You wouldn't have to, though the tune wouldn't be optimized for the addition of the cats. If you tune out the rear O2's now, then you wouldn't end up with a CEL after installing high-flow cats.

I vote yes on the HF cats. The stock cats are the restrictive part of the stock exhaust. Everything else flows well and aftermarket catbacks or axle backs change the sound but don't really add any umph! That happens with the LT and HF cats along with the tune. And yes I believe you will be back to the tuner later if you add HF cats down the line. If for nothing else the rear O2 sensors will need tuned out.

Seen a member on here selling some at a good price, might check on them. Now the frickin cats or no cats debate, geez when will it end?lol

I recommend that you get cats. Another consideration besides the volume (which may be ok for you) is that you may notice an exhaust gas smell without the cats.
