You all did great work on my 1994 Ford F-150. Serviced it for me with a tune-up, headers installed, and full tru dual exhuast. It is not loud but I think it is just perfect like you all said. I would suggest Mainstream to anybody considering the quality of workmanship that went into putting the exhaust together. This was my Dad's truck that I inherited 5 years ago and he would of been proud of what I did to it. Now I can saw I have a performance Ford truck instead of straight up stock. It runs real smooth now. Again thanks fellas.
