Vibrant Performance Sedan Exhaust (Finally)
I am very surprised you lost power with the intake. It should gain at least a couple hp. Were all the factors considered like airflow, engine temperature, etc? I have seen that if the engine temps are not the same between runs it will greatly affect power output.

I KNOW who you are referreing to and he has told me that we did it wrong and that the product works for everyone. He also demaned my dyno sheets I sent him to Kyle but nothing has ever been said to me after. I have no idea if he ever got the dyno sheets and I think I still have them....somewhere. I have seen you two get into it and all I ever say is I know some of their stuff is ****e. I had the powerbox or cold air box...whatever they call it. Made a hell of alot of noise and thats it. I wish I had let you know sooner but I keep low now. After StrictlyZ when out things got different.

And will the system be avaliable minus the Y-pipe?
