2002 292 fastech exhaust
 

I am removing my s/t box and have a few concerns. Do I need to change the factory tips? How about water coming back into the engine? How loud will it be? I looked into Corsa tips with baffles is that a good choices and will that stop water from coming back into the engine..

Thanks for the help

My 2006 292 came with the Corsa tips with baffles and the rubber flaps. It also has the Quick and Quiet which splits the exhaust through the transom and prop. Sounds good. Not too loud and it has a little rumble.

It should have short brass tips with Internal flappers. They are not the best looking things but if you just put some rubber flappers on the ends you can barely see them . Jeff wurl

Thank you.. Great looking formula! Do you have any videos of you boat idling?

Thanks. I don't have any video clips, but will try and remember to get a couple short ones while boating this weekend and post them up.

I did find a short clip of one engine running on the hose. The file was too big to upload here, so I just uploaded my first You Tube video. Let's see if it works...

That the sound I am looking for.. Sounds awesome! Thank you so much.. The problem I have now it that I am being told that just the tips will allow water to back up into the engine even with the baffles and flap...This project is giving me such a headache..

Hmmm... Not sure why that would be. My 2006 was the first year they dropped the Silent Thunder box under the swim platform. Maybe adding the Quick & Quiet II is necessary to prevent water backing up. Any water coming up the pipe would just drain down through the prop exhaust.

Your right on with the Quick & Quiet being the answer..

350 MPI's no silent thunder at 60% throttle. Stock Iron manifolds also.

You are running stock tips? Did you do anything about water coming back into the exhaust? Are you still running with out the box?

Still no box. Just installed rubber flappers on the factory tips. I have not had any water make it up into the manifold. I have taken several big waves to the stern with just the rubber flapper tips, even one over the swim platform onto the back pad with no ill effect. It used to bother me but I no longer think about it. Take the box off, mine had delaminated a little bit and sounded awful getting up on plane like someone was slamming the swim ladder cover over and over.
