      A:

      These Hooker 4 in. sidetube slip-in mufflers have been developed for vehicles with 4 in. sidepipes, such as those equipped with Hooker Super Roadster and side mount headers. The mufflers are easily removed for racing purposes, and are available in a performance-style glasspack or in a quieter, all-metal, reverse flow-style. We will need more information including the year, make, model, and engine size of your vehicle before we can make a suggestion.
