Anyone heard or know anything about the Whisper resonator/ muffler from zzperformance.com

If it is as quiet as they advertise, i might spend $130 on one.

Yeah, i am curious as well, no cat and full straight through 3" makes for a loud obnoxious demon child, i was hoping to tame mine slightly.

 

i was also interested but 130 is kinda expensive just for a muffler if it is just as loud as the one i have.

 

****, I might order two of those damn things if I redo my exhaust if they are really that quiet. I hate the loudness my Cobalt has. I mean my damn Integra with the 16G turbo and only the stock resonator off the Cobalt's exhaust is much quieter!

 

Well, a turbo will quiet the exhaust a bit, but i know our exhaust is loud as a bitch. Vibrant has a (supposedley) super quiet resonator for only a mere $100. I just wish we could have some sound comparisons. Serously, i'm about to cut out and weld in my original cat behind my long tube header just to quiet the bitch up.

 

The muffler was designed for the pontiac grand prix, which is a loud motor too.

I would like to hear one before i drop $130 though. But if not, i prolly will get it anyway and be the test car...

 

its just a resonator, you can get them from all kinds of exhaust companies

 

well, a straight through resonator that does a great job at quieting an exhaust is a hard thing to find sometimes

 

They say on the site that it can be used for a resonater or a muffler....

 

Bump, I want info

 

... it's not just any resonator... it actually is very quiet.
A lot of R&D went into this.
Compare the ZZP 3" catback (whisper resonator and a magnaflow muffler) to any other system. You understand pretty quick how much noise this thing gets rid of.
