Today we put the standard exhaust system back onto Ed's 370z but leave the Cobra High Flow Catalytic Convertors in place. How loud will the end result be?
I suggest trying test pipes for cats keep everything else stock probably give you what you are looking for. I personally love loud have a 3 inch z1 into a ISR y pipe on my 08 350 ears ring a little on long drives but I love it
@@leedfollow I'm sure that sounds really good. I just thought you should know that although HKS sounds really good they don't really make much power. I saw a video where somebody dynoed a car with HKS and then swapped for borla and made 30 HP. That's insane and hard to believe but the results were right there on the graph
