[peshaw_ss]

hello all just got a 03 launch and i want it to hear the 320hp that i feel. i know most want a super quiet ride, not me, i like to hear the muscle. any help (performance muffler-captains call-anything)would be good thanks alot

Buy some open old school headers off a 70's jet boat (old sanger), and cut out your swim platform covers to accomodate the exhaust, I have seen this done before.... crazy sounding, you gain an extra 30 horsepower! a little hard to lay out on the deck in the sun, but thats over-rated anyway! Surfing is also a little rough after this modification from the hot water and Co2 coming out the exhaust tips....

Just kidding... sorry, cant help you out . I think the CAT ETX EXHAUST is great, you still know its a V8 but you dont smell any exhaust and its not too loud.

just remove your muffler and have it free flow.....not sure if its legal but ya won't really hear it till ya take off

a dealer said water would get in if i were to do this since the pipes are under water line. does this sound correct even if i keep the flappers?

Buy a flat-bottom with dry stacks.....
Oh ya, and grow a mullet....

Do the newer boats have mufflers? I know mine is just 3" straight pipes all the way out - sounds really good. But if you want that above the water line exhaust outlet it's gonna take some serious modification . . .

You may have an in-line silencer that could be removed. This would be located in the mufflers somewhere, if you can see them you should be able to find it.

I personally prefer being able to talk and hear while I am boating.
