thanks derek.

WHAT, Tony, Say What???
I don't blame you, I sold my last Harley and Ducati several years ago and haven't really missed riding one bit.
It just wasn't the same as it once was.

The manifold exhaust ports are 1.312" square ports.
The heads have straight spark plugs.

As I get older, the need for speed and power becomes less of a priority. If it ain't broken, why fix it. I have long tube headers, but only because they were a deal at the time and I had no exhaust system. I still have 5 bikes, 3 little Hondas, a 250 Yamaha V twin, and my '89 carbureted Evo with 115,000 miles. I rarely ride it, but when I do, between the power, the sound, the waves, and the scraping of the floorboards, I can't part with it. As long as I have the strength to move it and pull in the clutch lever, it's a keeper. Besides, I have a drawer full of those black t-shirts.

The only reason Im looking at new manifolds is.....
the driver manifold is designed with the exhaust downpipe outlet MIDWAY.......
the passenger manifold is designed with a 45 degree downward REAR outlet which causes the downpipe to be very close to the firewall.

IF I buy a passenger exhaust manifold-only to match the driver manifold the connector downpipes to both sidepipes will be identical.
The starter will then have a few inches of clearance from the downpipe....alot less heat soak.

Just trying to eli inate future problems while im at it.

Thanks derekderekderekderek....I jumped the gun and bought the exhaust manifolds....the block hugger headers fit too close to the bock a d the starter for my li(c)king
a set of high quality CHEAP ram horns so the downpipes would be identical on both heads all the way to the sidepipes.

Whats a good brand of exhaust manifold paint since the are raw cast iron?????

Dupli-Color, VHT, John Deere 'Blitz' black, and Seymour 'Cast Blast' cast iron (500*F & 2000*F for exhaust manifolds).????

DG, I used Eastwood High Temp Coating in Factory Gray color on my new exhaust manifolds. Gave them a thorough de-greasing with brake cleaner and applied one thorough coat to them with a brush. That was 5 years ago and the manifolds still look great. I'd expect at least another 5 years before they'll need refinishing. The coating covers very well and dries overnight to a nice flat gray. The coating then cures the first time the engine is started. Let it run for at least 15 minutes(do it outside because it will stink up your garage quickly) and it's done. It's pricey at about about $45 per pint but one can will do probably 6 manifolds.
