They could easily have a tune for cats & one with LTH or test pipes and that would cover the rest because that is the only real restriction once you have the kit. Doesnt seem like rocket science to me. Also I am willing to be or more that any of us who bought the TT or SC kits have after market cats, exhaust, intakes etc... Just a thought for a better business plan. Dont get me wrong I like stillen, I chose them after seeing how not so great GTM's TT kits go together for 350z. I know I will be happy with my decision once we have my car tuned and done.
