Just finished installing my z06 callaway honker on my 2008/C6. Even with a very well laid out instruction booklet from callaway I was at a lost at times. Getting that cowling out is s nightmare in my opinion.Can anyone tell me if the oil clips are suooposed to go all the way around the pipe or just a click. I guess I will no tomorow morning. Corvette of houston says they do it in 2 hours. I took 8.I will say it is a HONKER. Its uses a k&n filter now with callaways name on it
