Question About Borla Collector Muffler

[TurboDiverArt]

Hey All,

Has anyone done any real world testing of these things? How much do they really quiet your car down? How much did they hurt performance? My Camaro had very limited clearance and although I have tried to fit a muffler under my car there is no way without modifying the chassis. Right now I’m running open headers with turndowns. No way I’ll be able to pass noise restrictions. I’m hoping that these things may do the trick. If anyone has any experience I’d be very interesting in hearing about it as well as what your combo is. Mine is a 468 BBC with 2 1/8” headers and heavily ported Dart heads.

Thanks for any input,
Art.
