It's the best choice to get the tubes, we run ours out the back of the valve covers to a vented catch tank mounted over our rear end.. Makes life a lot easier, but running a lot of boost we still only get a little blowoff in our catch tanks. MAKE SURE YOU'RE CHECKING YOUR INTAKE AND EXHAUST rockers! If one of them is way tight or loose, you have a problem..... Just my two cents :wink:
