4" turbo down pipe

[Maxtor]

I just talked to a guy at www.drivetrain.com/fordtruck.html
and he says that he has complete exhaust system from turbo back that is all 4" including down pipe for $495. Has anyone purchased anything from them? Sounds to good to be true.

BullyDog makes a true 4" turbo back exhaust system. Unless your pushing big HP the 3.5" Down Pipe will be just fine, then I would say go with MBRP. Fit and finish second to none. Dont get me wrong....my exhaust is just fine, but 409 Stainless is better. I normaly trade trucks after 4 years, so Im not to concerned if it lasts for the next guy lol.
