So are both of you using the URD y pipe??? So is this because the URD Y/pipe is designed to bolt up to the stock header?? Would a person have this same problem with all aftermarket headers??
Hey Nick-That is a problem that we know may occur. What we have done is started using factory 3.4 v6 y-pipe crush gaskets as they are a bit bigger in diameter and are a bit taller. Also they are available at any Toyota dealership. They work great and as of now we are going to start supplying them with new production y-pipe kits.
