Exhuast Upgrade:SSi or RUF style??

[willcall]

Hi all, I have a'76 C3 with the standard cross over 1 in 1 out system. I am wanting to upgrade to the SSI but realise it is both expensive and very hard to find for my model (I can't find any available on pelicans).
I found this photo of a '75 Carrera RS RUF with no SSI's.

Just wondering if I should do the same.
Would it be beneficial to have the RUF type?
Would it be louder?
Would it be cheaper?

I would be able to get it fabricated at one of the local exhaust shops unlike the SSI which would have to be sourced & probably shipped internationally to Australia.

Any opinions/experience would be great.

I should also mention that my C3 runs CIS and will be staying that way for good.

I think any SSI will fit the C3? Might have to change the exhaust studs if you get thick vs thin flange or vice versa (thats a hole different discussion).

The photo I dont believe is ruf? its just plain old headers with megaphones welded to a 2 out bannana. Very loud but cool.

Also straight headers = no heat. Are you Ok with that?

Oh, so there would be no in-car heater without the SSI setup.

The photo is of a '74 RS RUF that is for sale. I assumed it was the stock system RUF used.

I did not realise any SSi would fit. I see them listed on Pelican parts for various models with MFI. The CIS ones appear to be discontinued.

The only difference on the MFI SSIs is the connection for the warm up tube. I am of the impression that you could just cap that pipe for non MFI cars.

Now that I think about it the new owners of SSI are advertising different pipe diameters so you need to make sure that they are the right size for a 3.0.

Yeah 911s get the heat off the exhaust, if you want heat in the cabin you cant go straight headers.

Thanks.
When it comes time for the exhaust I'll take the measurements and find the appropriate model.

SSI only made one tubing size (1.5"), so if new owners are reporting a different size it ain't SSI.

Those look like "European" headers on the car adverstised as Ruf. Be careful with that as you can add a Ruf emblem to anything.

Get a set of SSI, and a muffler from Rarlyl8.
