Are there any dual-mode mufflers (ala C6 Vette) for the S197? I like how the engine feels and sounds with my Pypes Violators above 3000 RPM, but I do not like the drone and interior volume under 2000 RPM.
It'd be nice if we could get bolt-on dual mode mufflers that open her up at a certain RPM or setting.

 

I think the Saleen center exhaust is like that (it has the center tips but also turndowns tucked up behind their fascia).. someone will have to get you better info. I don't know if it changes the sound, or just allows better flow that the extra piping to the show tips

 

Have you considered these?

Interesting, I never knew they did that....hmmm.

 

Are you referring to cut-outs?

 

IIRC, those are essentually cut-outs. In normal driving, the exhaust flows through the center tips. Under certain (full throttle??) conditions, I think the hidden turndowns open up via vacuum actuators for a free-er flowing and louder exhaust note.

 

i've fitted the Saleen center exhaust kit on an S197 recently.
the exhaust that came in doesn't have the vacuum operated bypass..
i guess those only come on the original Saleens

 

I think the GTAs sound the best. no drone and sound great.

 

I will have to fight you on that and say Bassani's are better, but then again, this thread was about cut-outs so yeah...

 

Do the Bassani's drone?

 

The Bassani Street AB's do, I've never had their Race ones though.
