Exhaust baffle cut off mod

The basic concept around this modification is to bypass the baffles and reduce the distance the gasses travel inside the exhaust canisters (cans), which creates a throatier, deeper, more V style sound. Basically, instead of the gasses performing two 180o turns, this mod allows the gasses to travel straight from the front of the cans to. here's how i modified the baffle plate. drilled 2 small holes in it. this allows me to retain the actual baffle and it's not nearly as loud as when you cut the baffle off. the 2 small holes open up the restriction of the baffle plate and give the exhaust more flow. these engines don't give off a lot of exhaust or a lot of pressure, so 2 small.
