I just finished my estimated 45min test pipe install. Both right and left sides on the catalytic converter had some bolts that Nissan put on with a kick. It ended up taking me four freakin hours. The two bolts were both the very top forward part of the cats, outboard side. Did Nissan do this intentionally? Both destroyed themselves on the way out and one I stripped.

Fair warning!....If you go through the top part of the engine bay with a ton of extensions you can get to these bolts....DONT USE A 12 SIDE SOCKET! I learned with the first one and went with a 8 side impact socket on the second. You will need every last amount of torque you can get. I got the second bolt loosened no problem but it had destroyed itself to the point that it was just turning. Getting the sucker out required on person pulling on the cat while I hit the bolt with an impact gun.

Please, don't go through what I went through today!!
