Wow, speaking of sliding, my dad takes me sliding on the dirt road in it all the time! It's awesome! Even though it did cost us a tire once =D
I like the c4 suspension idea along with the flowmaster idea. I heard this 88 IROC with the muffler cut off at the converter once, and that thing sounded TERRIBLE. Besides, I want it to sound like a v8 while still being a v6, for now. My dad said something about this muffler setup that came with these disks that fit into it, and each one you put into it gave it a different tone. Know anything about that?
