Question Porsche OEM 930 Mufflers?

Curious, did Porsche ever make any dual outlet twin-pipe mufflers for the 930 turbo, or was this only available on RUF BTR/CTR's?

If anyone is selling a dual outlet, twin pipe RUF muffler, I'd be interested in dealing.

I know there are other altermatives, like FabSpeed, B&B, GHL etc, but I want the sound of the RUF muffler

I contacted RUF and they sell the twin outlet mufflers for..... ~USD$3.5k!!! What a rip off!

If you're talking about the versions up to 1989, Porsche never made one for the regular production cars. That's not to say one didn't end up on a car built in the Special Wishes department. Ruf has the best known version. I'd wager that you could make one yourself from a stock Euro muffler.

When you say "stock Euro muffler" are you referring to the twin pipe, left side exit muffler, with dedicated wastegate dump pipe inlet?

Anyone have a pic of what one of these looks like (especially inside)?

James,

Yes. There was also a version (that had twin exit pipes) that didn't have an inlet for the wastegate. The wastegate on the later cars had it's own little muffler.

I've read in some other post that someone tried to add a 2nd outlet to an OEM Euro Muffler and it didn't work out. Apparently they got a lot of resonance between 2.5-3.5k and it sounded crap.

I just wish the factory made a properly tuned and quiet dual outlet unit
