IMO these are some of the coolest headers for a highboy. Got my set installed today. I'll let ya know how they sound and run this weekend.
The baffles and turnouts are not in yet.

NIIIIIIICE. Equal-length headers work so much better than those cheezy shorty units.

What size are the primaries and collectors ? I am impressed with them too.
Yeah, You're still doing without a crossover pipe so you're doing without the benefits of all that scavenging. But heck, when I'm done, this car will go too fast anyway. And looks do count in this hobby, right?Quote:

If you're talking about an X or H pipe between the banks of the motor, you may find that they're more about mellowing out the sound than they are about power. It is possible to over-scavenge and actually lose power down low in the rpm range with an X pipe. Not so much with an H pipe.Quote:

Yes you could swap the tips and bolt to an under car exhaust.
Yes I was talking about an X or H pipe. I've never heard of over scavenging, I'll do some more reading.Quote:

I meant to take a pic of the baffles before I put them together, but I forgot sorry. I'll just have to describe them. They are like most glass packs that I'm familiar with. They are about 2 to 2-1/4 inches inside diameter and go the full length of the collector. So they are about 12 inches long. The inside end of the baffles have a collar that fits snug to the inside of the collector so exhaust is forced down the center of the baffles. The pipe has a series of louvers punched in it all the way around the baffle, and along it's entire length. They came with a very small amount of packing around the baffle. Really only 1/4 to 3/8 inch thick.
Would more packing around the baffles help? There's room for an inch to an inch and a quarter of packing between the outside of the baffles and the inside of the collectors. That would be 4 or 5 times thicker packing than was on the baffles as shipped.
I've also been riding motorcycles for about 43 years and I've seen people put a bolt or two through the baffle to increase back pressure and quiet the muffler some what. I might do that.
Any other suggestions?
I've seen both fiberglass and high temp steel wool used for packing. Anybody have a preference? Any other materials that are better?
Pack it with S.S. wrap and s.s. clamps (like zip ties) Did it on these and mellowed out real nice.
You'll notice that the coupe was in the Sanderson Booth @ LARS
Beautiful cars!Quote:

Fiberglass muffler mat first then s.s.Quote:
