Overall Assessment

Customers have highly recommended our product for its excellent quality and usability. The product has been praised for its great look, perfect fit, and the ability to bring down noise levels. It has been confirmed to work well on various models like Ford hi-boy, T-BUCKET and '32 roadster. Users also appreciate the heat shield feature for preventing burns while exiting the vehicle, thus adding safety. The product's sound quality is also appreciated, described as mellow when driving but powerful when revved up. It is, however, mentioned as a bit heavy. One user also reported that the product wasn't as loud as anticipated but still impressive, adding aesthetic value.

How far over the 3.5" collector do these extensions slip on? My T-Bucket has a very short wheelbase and from the front of dimension "C" to my back tire is only 59". I would like to use the SBF sprint headers and these mufflers. Will they fit?
