I had an exhaust shop install my my magnaflow system along with banks torque tube headers. The four inch tip has a tuff look. The sound is deep and makes my truck sound strong. I have not pulled a trailer yet. But on the hi-way I gained 1.5 MPH.

Very good product

Easier install than I thought it would be, took about an hour. Sounds good, looks good.
