Trying to get this zzp catted converter into my gp..the two bolts that go into the engine block came off with one second on the impact gun with the right extensions, they came out in a minute. The ones that go into the resonator are really stuck. The 13MM socket hardly fit on it right away, had to hit with hammer, then the bolts just wont budge.
The impact 13mm doesn't fit they have rusted pretty good. Tried pb blaster, been soaking the bolts for a couple days. Tried torching one of them to get it hot, and no budge. The one is starting to get stripped, the sockets slipping off, not too bad but its started.
