uh with a powercommander and custom map, which will be all together another $300-$500 probably 10hp. The full system seems to be a little deeper and louder than a bolt on. its nice, but i kind of like it a little louder. its up to you. if you just cruise no you won't notice the difference with weight, but you should still notice the power with a map, and of coarse the sound
Hold up a full Ti system and then hold up a full Stainless system, once you realize the weight difference you'll understand why Ti is better. Plus it looks way cooler (the purple and blues)!!! And full systems always sound a hell of a lot better!
