What's the deal...some Steggy stage IV's have an "oval" and some have what looks like a "figure 8" cut into them. Are these examples of old and new designs??? Which is the latest and greatest???

Oh and what about filling the silencer holes??? Do or don't???

Some say it works and some say it doesn't???

I was thinking about using aluminum instead of JB weld to be safe.

I haven't decided if I'm going with Steggy or a home port???

Later...Dave

Use the proper epoxy.
Prep the area as per instruction.
The design on the outlet side is different porting stages.
I think the 8 shape you refer to is Stage 5.

This is Stage 5 outlet shape:

Stage 5 and 5+ yeild the greatest RWHP and RWTQ.

So you agree with filling the holes...it works???

Just epoxy??? Why not use aluminum, would't it be stronger with less chance of falling apart???

I'm confused about which is stage IV and which is V???

Many posted pics on various threads have been titled stage IV but show either the "oval" or "figure 8" shape. I thought that the design of stage IV changed as time passed??? So what your saying is stage IV is an "oval" and stage V is the "figure 8"???

I thought the outlet port was same on IV and V with a torque plate added on the stage V???

Thanks for clearing this up before I pull the trigger!!!

BTW, I sent you an e-mail (Stiegemeier) a couple of weeks ago about this without a response...can I resend it???

Later...Dave
