Ive got the car all jacked up on both sides in the front, trying to remove the stock cats. There are those two nasty bolts way toward up toward the engine im having a hard time reach - what tool did you guys use to get those 2 off?!? I already soked the bolts in wd-40 and ive got 6/10 loose.

Thanks!

i think with a long extension, you can reach them from the engine bay.

 

finished it after about 8 hours of work. Took awhile to assemble all the right tools and get everything straight.

 

So how do they sound?

 

Sorry I did not reply to your PM in time. I hope everything worked out. I think I wrote a install how to here, so maybe that helped. At any rate, you use 2 12" extensions with a socket knuckle and a 14mm deep socket. The "daisy chain" is long enough to go through the engine compartment and land on the nut. Makes it pretty easy. As for removing the O2 sensor, you just need a 22mm boxend wrench or a spanner set to 22.
