    15803 is rated 3.7 out of 5 by 3.
    Rated 5 out of 5 by from Fit well Pipes fit well actually had to cut about 8 inches off the front but my mufflers aren't in the original location A couple of clamps and good to go
    Date published: 2015-11-15
    Rated 3 out of 5 by from Came up short I installed the tail pipes and they don't quite come out far enough. Other than that, it was a good fit on my 1987 Chevy.
    Date published: 2016-05-26
    Rated 3 out of 5 by from Needed some tweaking Bought as a bolt on install and the left side did but the right side needed some adjustment chopsaw and a wire welder did the trick. Would have been a bolt on but my 3500 has a brake valve on the rear brakes that caused the problem
