I'VE GOT JUST THE STANDARD 330 EXHAUST ON MY 454'S. THE STOCK EXHAUST TIPS ARE ONLY 3". THEY LOOK PRETTY PATHETIC ON SUCH A BIG BOAT. I WAS WANTING TO CHANGE THE TIPS FROM 3" TO 4". MY QUESTION IS, DOES ANYONE KNOW WHERE I COULD FIND AN ADAPTER TO DO SO AND WILL THIS CAUSE ANY TYPE OF PROBLEM WITH MY EXHAUST BY INCREASING THE TIP SIZE?

THANKS FOR ALL OF YOUR HELP.

I would call Corsa. Replaced my tips recently and these guys really know their ****. I believe the guy I spoke to was named Jim.

This is their business, and where I would start.

I will give that a shot.

Thanks Doc!

I've never seen any 4X3 tips...but alot of stuff I've never seen..I don't see why someone couldn't modify tips to work for that....not to familiar with the stock 330 set-up either some help I am ...wondering if the 4 " tips would fit or would you have to enlarge the transom holes ?

Oh yes, I plan on enlarging the transom holes for the 4 inchers to fit. I don't think that should be much of a problem......

shouldn't be...might check w/ Brownie @ Stainless Marine too

CORSA has them, both straight cut and angle cut. I think around $240 a pair. Give em a call.

"EXHAUSTED".....I think you misunderstood, I know where to find the tips, they are everywhere, it is the hose that runs from the risers to the exhaust tip that I am looking for. I need one end to be 3" (end for the stock riser) and the other end to be 4" (end for the new exhaust tip). ????

WHITE-DIAMONDS, the tips accept the 3" hose from your risers. The 4" tip is dropped down inside the boat to 3". Hope this helps.

Ah............I got you. I just checked with Stainless marine, they have them for $59.00 each.


Thanks for your help guys.
