Thereisnospoon, You would like the sound of the Magnaflow 15609, you will notice virtually no difference under normal driving and cruising. The only difference that I hear in the 1.5 years that mine has been installed is from the rear when my wife is going down the driveway or at wide open throttle. Nothing like flows, not even close to that mettalic raspy sound. I did cut the 4-inch fart can tip off so mine only has a 3-inch stainless steel pipe exiting in the stock location.

 

Check out www.ststurbo.com This is a site of an undercarrige turbo system.It is by far not cheap.I am going to inquire about a system for my 06 4.2, and it should bring around 100+ horses to the table with the insall when it happens.you can boost around 4 to 5 pounds on a street system or up to 15 lb.boost on a twin system.I did not say they have one for a 4.2 but they have done different v-6's.Don't get bumbed just get a second job to pay for you pleasure.
