Hi Chris, Just about anything you do to the exhaust system will effect the power output. The SVX has a "tuned" exhaust. The little "muffler" after the cat is a resonator. Without that, your performance will take a hit. If its already leaking along with the rest of the exhaust ypu are losing power. If all you want to do is keep from getting carbon monoxide poisoning, you can do what ever you want. Take care, BOBB
