SPF exhaust with clam open

[Mark H.]

Anyone with an SPF have any idea(s) or attempted to deflect the exhaust with the rear clam open with engine running; shields, temporary add on pipes, high temp hose, etc...? Would make tuning a bit more convenient.

 

[Dave Hood]

Best to remove the clamshell, but temporary flexible exhaust pipes would work.

I made one of aluminum, works great
Will take a pic and post.

Dave, don't think of metal hose but when measuring just don't have the room.

Bill, any pictures appreciated.

Opps,I forgot,, I'm putting my camera by coffee pot,

2x2 alu angle welded formed alu to fit through the rear of the clam when open. With out much effort it could be improved.
I made this and use it when synchronizing Borla injection.

Thanks Bill that helps.
Another question, how did you mount the heat shield on the clam shell, above the mufflers? Looks like it stands off the surface an inch or two? Am thinking of doing the same to protect the shell.

 

[Bill Kearley]

I felt I wanted a little heat protection !!

 

[Bill Kearley]

I just set it there for the foto. When in use I secure it with a strap that I keep away from the heat.

 

[Mark H.]

No, I mean't the shield on the clamshell itself. Looks like it stands off the surface an inch or two?

 

[Bill Kearley]

Yes it does, about 1/2 inch with 10-32 rivnuts and screws. and sort of an overlap with a piece bolted to the back of the intake manifold

Thanks Bill!
