Is there a trick or any helpful tips on removal and installation of the inner 2, lower y pipe bolts?? In preparation for installing my estart next week, I pulled my y pipe off. One inside lower bolt was missing an the other was a P.I.A. To get out. The other 6 were easy with my t handle. Is there a special wrench to get at those inner 2? Thanks in advance. I'd like those 2 to go in nice and easy when I re-install the y pipe.
