Primary muffler bypass?
 

Good day!
I own a 1994 964 RSA. I find my engine very quiet - I would like it to sound a little bit more aggressive and was thinking of replacing the muffler with a primary bypass. Would the bypass be too noisy?

Dan, I replaced the primary on my 91 C4 and I love the additional sound. Not too loud, but much better than stock. Follow the directions in the tech article. This is an easy install. Good luck!

Thanks KF. I did read the article, it is very easy.

Dan,

I have a RUF muffler bypass with RUF exhaust tips. I had this on my 93 C2 which I received many compliments on the sound. It has a deep rumble which sounds sweet. If you're interested, I can forward you pictures and price.
