Yes i did, the gains were so poor and the price so high that i couldn't justify it all si i have let it go. Catless produce way more power and are cheaper and that is where the market it. With the results i saw, i don't see the point in going after market primary cats over the stock units. Sarah, you will get the most power upgrade out of a tune anyway, if you want to try one out, i can let you do that for a week, no obligation.
