That almost looks like it's for an outboard??? What is the id of the intake side?

Nitro boater

Yes it is an outboard pipe

It's a HTB Silverbullet for a 65/80 engine ... can't find the (right) website anymore (htbboats.com)

I was thinking the same but it looked a little longer than the one shown on the precisionboats web page.

That is my argument,look at the broad band section and what size motor is this for?

I think I have the correct description now of this pipe. I am positive this is an old Aerotech 7.5 pipe for the OB. The grooves in the seem are the sign(they were to stop the nylon ties from sliding going by the pick I am looking at (RCBM September 1994 page 19).
How does it work Dave?

I tried Joe Monohan's 707 Specialties site and it appears to be closed as I can't get in. Joe sold Aero-Tech boats plus a lot of aftermarket parts for K&B outboards. The HTB site is also DOA.
Bob Kinsell bought the forms for somebodies OB tuned pipes but I don't know whose.

www.707specialties.com or [email protected] sites is still up, just checked-got my shafts from Joe last week
www.precisionboatsracing.com for Mark Hoppers HTB hulls + more

Bob has the Equi dies and has made offers to sell the pipe in partsunwelded to many,but has yet to reply to anyones emails,

Bob and Karen moved from Fort Wayne, Indiana to somewhere in the Atlanta, Georgia area not too long ago, he still has a daughter that lives about 20 miles from me yet so I don't see them around any more..

you will have to use the google search link when you click on those links for some reason, but the sites and products are there. Maybe someone can put up a better link.
Had an email from Bob on the 8th offering to sell me the parts but cant get a reply since.
