Thanks for posting so quickly, I have installed the 105 in a Aeroworks Edge 540 33%. Hope it comes in a around 27# do you think that will be enough Engine for 3D

All the parts including mufflers I bought from DA. You can get a exhaust flange and what ever pipes you need straight, 90', they are thin wall stainless steel, they snap together to make it easy to braze (silver solder). Like Tim said it's not hard to make your own.
order a couple extra pieces to practice with make sure you buy the silver rod from DA also it has flux on it and works well on clean pipes heat till cherry red then apply the silver rod it will flow in like solder on a water pipe. Once you do one you will not be looking for headers ever again you can make any shape or size you want or need. You will need a Mapp Gas torch $40.00 at home depot, it's like a propane torch except it gives off more heat enough to braze with.

Thanks
