RUF 930 dual outlet exhaust on EBAY

Werk1..I had to clock both sides of the turbo in order to make things fit right. I ordered a turbo oil drip tank from fabspeed. The one I had would not work with the Ruf muffler. If you need a pic let me know.

Emptytank...that was funny..

In 1985 a customer of ours buys a Ruf BTR from Ruf and sends it to our shop. Then he wanted a louder muffler. We took this one off and it has been on the shelf for 37 years. I don’t see any Ruf markings. What are your thoughts. Is it a 930 S muffler that Ruf used?

As far as I know, no. The 930S or 930SE exhaust had an exhaust setup that had the wastegate exhaust exit out the driver's side. While the passenger side was muffler exit.

RUF didn’t actually make their own exhaust back then, this is what they used for their BTR builds. My guess is they just didn’t weld their plate on this one. I recently had a Bischoff with this same part number, and it had a RUF 4R tag welded on it. I only see a very minor difference in a jog on one of the pipes mine had that this one doesn’t have.

It’s definitely not the power kit exhaust pictured above, that exhaust is a spare I bought for my 930 WLS.

I had the same one on my BTR, it had no RUF markings on it and from memory it weighed 17 kg.

If someone needs the Tüv test report for this Ruf R4, I heard it when I bought it in 2013. then just contact me.

I was tipped off to this discussion by another member who knows I'm in need of a BTR muffler, one I got rid of many years ago, like 20? That one sustained water damage so I didn't think it was useful at the time. I got rid of the engine too then. I was much younger and thought I would not be doing it back to Ruf BTR III spec. Recently I've acquired a BTR motor which is being rebuilt. I really would like to keep the car original or bring it back to how I got it 23 years ago. It was 964 turbo look, so the muffler outlets came straight out the back, not sides. I remember there was a RUF stamp into the bracket somewhere. I sold it on the yahoo auction back then. Finding one like that may be impossible. Any advice? Thank you in advance for any help.
