Monty, that is great = info. =20

The turbo - engine is = good. I=20 use the stock manifold that is very beefy iron and a very short moment=20 arm.

From the turbo outlet I = currently=20 have a 16G 321SS down pipe that is about 18" long going right = down out=20 of the cowl. Easy enough.

I plan to hang = the muffler=20 under the cabin, so all I need is one bend going from the current down = pipe to=20 the muffler, about 2' away (with another small bend just before the = muffler for=20 alignment). I was thinking a slip joint onto the down pipe, then = another=20 onto the muffler.

This should work fine if I am = envisioning it=20 properly. Something like what Lynn posted should work fine for your slip = joints.=20 No need for the metal bellows after the turbo. All they do is seal the = slip=20 joint. They are just a really thin metal tube formed like an = accordion. It=20 is welded on the upstream side and downstream side of the slip = joint to=20 seal it.

Otherwise it becomes a piston. Not a = concern in=20 your case. This would be an issue if you were making a = new=20 manifold between the engine and turbo.

Bernie's ground straps are what I was = after when=20 referring to wire rope. Same difference with a lower price tag. = Also you=20 don't have to worry about the silicone degrading from high temps. I = think=20 they would be preferable for this reason.

No, you need the slip joints to allow = relative=20 motion. The V-band is just a nice clean way to attach things. =

Not sure what you mean-did you mean = metal bellows?=20 see:

to get an idea what I am talking about = look under=20 braided connectors.

Thanks for your = help.

No problem, just remember it may be = worth what you=20 paid for it ;-)
