I am interested in purchasing a new cat-back exhaust. I was wondering what the sound level difference is between the hks hyper and the gready PE. I have heard the PE and thought it was relatively quiet. Or if you would compare the hyper to stock (subjectively of course). The Hyper is about $200 cheaper then the PE or similar exhausts. Thanks for your input.

 

The Hyper is much louder than stock I can tell you, the Greddy PE is pretty mild in comparision.

THe Hiper is a lot louder than the stock exhaust. If you add a downpipe with the Hiper, it is VERY loud. It sits crooked (pointing to the right). THe PE is a more "tame" souding exhaust, yet still louder than stock.

 

HKS = Fartcan
Greddy PE = 3/4 of a Fartcan
Stock = quiet.

If I was to get another....

2. m2
3. Greddy SP (what I currently have)
