Well..I got some cash and am Going to the Track on the 15tth. I am readly going to get me a Carb Spacer for it. Soon I hope. I really want hit 16's But I dunno lol. Just wondering...Will Cut-Outs do a thing for me but make me loud. Will they need to be placed in a certian sopt to gain good power. Its a cheap mod and I really liek the sound but I dont wnana do it unless i get an actuall gain u kno. Wat u guys think?

They will help slightly, but your carb will need to be re-jetted to make the most of them. The best place is directly behind the collectors, or as close as possible.

Yeah, with a more free flowing exhaust you need to rejet. They cost next to nothing, but just arent too much fun to put in on a QJet.

I just jetted (rod) mine down for the winter since its raining alot and I really dont want that extra power, its definitely slower, but I get better milage. I was suprised how much you need more fuel with a better flowing exhaust.
