I have a '77 Kona (day cruiser) with a BBC with the hardin exhaust logs. One of them finally let go & started to leak h20. I bought a set of used Hooker water injection headers but they wont clear the gunnel by aprx 3". Ideally I would like to throw a set of Gils I have laying around but I dont want to hack up the transom. Doing this on a tight budget, anyone have any recommendations ?

Does it have over the transome exhaust? The Gils might work with different pipes. Maybe some TRS rise pipes that go straight back.

The current exhaust is thru transom but oartially submerged.

duh...whats a gunnel?

Top of transom/sides of deck in the cockpit area.

Those old exhaust logs robbed a lot of power. You might be able to alter your Gil pipes to fit.

Thats for sure, I bolted up the Hookers backwards just to run it in the driveway. Holy s**t, could tell the huge differance right away. Was hoping CP Perf in Cal had a solution.
