Exhaust thoughts??
Have of course a ZR1 with dual 3 inch pipe and magna flow mufflers from previous owner. Headers with no cats. It is very loud and cant stand the deafening sound and drone anymore. I have just purchased dynomax racing bullets for right off the headers and dynomax ultra flow ss mufflers for the rear. I hope this combo quiets it down a bit. Any thoughts? Thank you!

Re: Exhaust thoughts??
If it were me I would purchase the Corsa system......if cost is a concern look at the OBX system on xbay for $500. Either system should quiet the drone to a reasonable amount.

Re: Exhaust thoughts??
Yup, Corsa.
Best overall suppression of resonance (a tiny bit still at 3200) HQ stainless steel. Easy installation. Great looking tips. Reasonable $ Is not glass pack so will last. GREAT SOUND when at WOT.

Re: Exhaust thoughts??
Follow what mike100 and myself have done using Z06 tips and actuators. Less expensive than Corsa, bigger diameter, weighs less by eliminating the resonator.
Badass sound when you want that.

You can see hear in this video how the NPP system mitigates the sound. At cruise, they do are great job at eliminating drone. Also significantly less expensive than Corsa, larger diameter, less weight.

Re: Exhaust thoughts??
Those of you suggesting Corsa have you guys heard what they sounds like from the outside the car at WOT.
Sounds like a broken down lawn mower, fart can. I like the old school big V8 rumble. Here is my exhaust at 7200 rpm https://www.youtube.com/watch?v=ZlRIOMwaDYY Pete
