I just do not see how this product works as they state. Since your putting the product right infront of the header tubes as they come togther at the collector.

A well designed exhaust will do you right. A good muffler will be the biggest help rather than a add on trick. The hardest thing to recomend is a muffler based on what sound you want. Wrong muffler, wrong sound, you hate it and spent alot of money trying it.

I'm running Hooker Aero Chambers. They sound a bit different on the outside, but inside I can carry on a convo with the stero on without effort.
