Description:

I put the stock secondary cats back in before I sold my wife's GX, finally getting around to listing this for sale.

URD y-pipe for 2010+ GX - https://urdusa.com/urd-off-road-y-pi...0-lexus-gx460/

Before and after dynos here:

Way better ground clearance and a few more hp's.  Gas mileage was consistently 1mpg higher than prior to the mod, it just took a week or two of driving for the long term fuel trims to catch up with the better flow from no secondary cats.

Looking for $450 shipped.
