Has anyone ever routed exhaust pipes through the Silent Thunder platform so they connect to the pipes coming out of the transom? I've got one for an 87 206LS which I took off due to drag and rattles. Any ideas?

Thanks!! That is exactly what I was looking for. It looks like a few fabricated pieces and standard exhaust hose. Sounds easier said than done. This may be a side project.

If I remember it right, he had to have custom tips made for the outlet ends (the square tips). I don't recall all he did to complete it. Try searching or any other threads by him.

I dont think I ever heard how it worked out ....

I spent some time searching old postings today and I found a lot of info. Check these out and see if it sells you. It looks like Ramb. originally drilled some holes through the baffles to add a little noise. Later it appears his boat sprouted wings and busted the platform when it landed. From here I think is when he went with the routed pipes. I'M SOLD!

I am working on this same project and I just got some new tips in for a diffrent look. Tell me what you think. I am going to use a coragated exhaust hose so it will bend inside the platform. I`m using a dremal to cut the inside it works great.

Looks good, I guess your putting flappers over that tip? How much does that piping cost? I read in one forum that flexible exhaust hose runs around $1.75 per inch! Yikes. Are those tips the same size as you would find on the transom? How did the square to round transfer go?

PierPressure

Disregard the flapper question. I finally opened my eyes and saw the internal flapper in the close up.

I'm leaving mine alone. I like it just the way it is.
Well, maybe I'll cut the baffles out.
Beyond needing new transom and exhaust seals it's just fine.
