Double reply. It's the 4th, so everybody must be partyin and not respondin. I'm at Work..arrrggghh.
I did some research on the reduction of backpressure with supercharged cars, and most people say it reduces power and boost. I'm u "un-technical", but if somebody knows anyting objective about that it would be appreciated. |

Our objective with the Noweeds dual valve diverters have been expressly to enhance the sound of the vehicle throughout its operating range.
Yes, they will enhance the sound of any V8 Camaro, some more than others. In Dyno testing, with open diverters, we have generally experienced a higher peak HP number. The video posted is of a NicKey Stage II S, and it does feature our Old Skool style Stage II Cam. It does have Hi-flow cats as well. We have been using the systems since the first 5th gens rolled off the transporters and have logged tens of thousands of miles with no issues. |

Yes, you can say that we have had some experience with ZL1s.

Personally I wouldn't put them on without headers or HF cats, because you will be very disappointed with the outcome with the OEM cats.

Is that because they are so restricted inside that it doesn't really matter what's downstream? I saw an old thread where somebody ur the ZL1 cat one and it is really restrictive to air flow.

You see there's the rub, mine are so loud with HF cats I can't drive with them open all the time. I've heard mine before and after the HF cats, and before they sound around 2X louder than the exhaust normally does. Here's mine ...
