Hey guys i am looking for an after market exhaust system for my ski. I want my jet ski to sound good and have a louder exhaust. what are people doing for exhaust systems. this is my first one and i dont know anything about them. so if someone could direct me what i need or what to buy, or even if i could hollow out my exhaust to make it a lil more throaty. i know ive heard some skis before that had exhaus on them. because they sounded a lot louder than mine.
