Burial exhaust from Graphite9

[LMH]

The exhaust looks real neat and definitely quality welds. I wont have time to throw it on a bike for a bit but Ill get some measurements of it all and get it wrote up later. For now heres some pics.

It arrived perfectly sir! My postman held it at the post office for me while I was out of town on business. Funny enough we have each others cell numbers so its easy to coordinate deliveries.
Im very pleased with the builders quality of material and craftsmanship. Thanks for finding us these awesome exhausts graphite!

Scorp from red eft outlet pipe inner diameter vs burial, scorp first section vs burial first section, chamber scorp vs burial, and outlet scorp vs burial.

[LMH]

The scorp has a lot of sections or Id post them all as well but the lead volume is definitely more on the scorp vs the burial yet the burial has a larger outlet. Theres a lot more more before the chamber on the scorp is what Im saying even though same 1st section size and chamber size as the burial.

What bores can this pipe be tuned for? has it been tested or is this just a cheap sell.

[Red Eft Performance]

Hello The Burial pipe is meant for 90-110cc.

The scorpion is for 72-82cc

The chamber of the Burial is made from a 90cc pattern. How well it works on a 72 remains to be seen.

I will be interested to see what you find with this pipe cause no one has tested it including the place where it was made.

The chamber is the same size diameter and length on the burial as it is on the scorp from redeft. The burial uses the larger outlet tho. They both use 28mm lead pipe ID also, the scorp has larger lead volume though and more sections. Theyre very similar in measurement pipes, I doubt internally that they match tho. Also the scorp has more of a smoother transition from section to chamber. Im really interested in the performance and sound of the burial though. It looks rad!

I thought there was a page for pipe measurements on here but I guess it was another site Im a member on. Maybe Wiki would be a good place to do a page for pipes. Theres a ton of knowledge on the rare ones from Sanjuro, tru72, bakaracer, trafficjamz, redeftperformance, graphite9, and a few others who have had pipes imported and still possess them.
This drawing is a good example of what measurements need to be made in addition to the stinger lead pipe and "J" header pipe measurements. Angles are important but its a bit of overkill. If the measurements are off by 5-10% its ok as its human to error.

I'm will create a 'wiki page if folks provide dimensions.

For pipes like the Burial, Scorpion and PG. Does how can we get the tail cone and belly dimensions?
That would be L5, L6 in the diagram LMH posted above. Also, L7 may be an internal stinger from the end of the tailcone to upstream within the pipe.

We need a convention for measuring length of the curved portion of pipe -- middle might be best?
