They do in fact have stainless, as that's where I got the donuts I used on The Mule's exhaust.Emc209i wrote:Does the chassis shop make stainless 304 or 321 doughnuts..? I didn't think they did.
Edit: I just checked and they only sell mild steel. That won't work on a Ferrari.
The stock 3-1 manifolds don't look any better than something GM might build for a Caddy, and are probably built that way to keep the catalysts as close to the exhaust ports as possible.CincinnatiFiero wrote:I assumed Ferrari would leave nothing on the table in terms of exhaust performance gains, until I looked up what is on there now
I think he went with the giant Dr. Suess collector to accommodate his catalyst, which to me looks like an OEM cat off a turbocharged Mercedes.

I'd say there's some substantial gains to be had from a proper set of headers.
They do? Can you show me, I can't find them. Maybe they're discontinued? All I see is mild steel and chromoly.The Dark Side of Will wrote: They do in fact have stainless, as that's where I got the donuts I used on The Mule's exhaust.
He starts with bare catalysts... just the monolith in a tube (looks like a bloody 6 inch tube) and welds up some pretty wild offset conical ends with odd entry and exit angles. They may also be used on Mercs, but he gets them without the Merc ends on them.CincinnatiFiero wrote:Those big band style clamps is how they attach on some turbo benzes, though I haven't worked on one in a long time. I don't know that for a fact, but that was my speculation as to why he went with that collector was with the catalyst in mind.

Only so many ways to skin a cat... I'm sure the Merc units look very similar. For all we know it could be the same catalysts as Merc V12's use--that would make sense, right? Need to put a cat on a 500 HP V12? Find some that are already used on 500 HP V12's... He's just in touch with the parts suppliers that get him the naked unit. (that sounds pretty kinky)CincinnatiFiero wrote: I was looking at this pic it looks like something off the shelf in the CAD picture, I didn't realize he was "making" them, it really doesn't matter what they did or didn't come off of, just looked vaguely familiar.
