I just installed FI non resonated test pipes a week ago. About 20-30'' worth of extensions are good enough. you can rent a breaker bar from autozone that's pretty solid. There are 2 bolts you need to remove from the engine bay, You dont need to completely take off the g3 intakes, you need to take off the 3 point strut and just the top tubes so just loosen the clamps and pop those out and put it on the engine cover. The passenger side bolt is very easy, the driver side however, is difficult due to the steering column. A 1/2 drive extension will not fit, use 3/8th extensions and make sure its long enough to give you room to break that bolt's torque. A universal adapter is a lifesaver but I broke mine trying to get the driver side bolt out. As for the rest of the bolts, since i didnt have a universal adapter anymore i had to jimmy 2 wrenches together to get them out. Taking out the bolts is easy just time consuming. PB blast it overnight, it kinda helps to soak tissue or toilet paper with PB and smudge it onto the 4 bolts under the car so it can continuously soak the bolt overnight. Also, becareful w/ the o2 sensors :P I was lucky enough to not strip any of the bolts. Have fun and good luck
