I have been a fan of Dynomax for a long time. I am still piecing together the exhaust on my truck and found a good deal on Dynomax Super Turbo mufflers today at
www.rockauto.com. The part number is 17732 and they are 2.25" offset inlet/offset outlet. Just type the number into the part number search and set the manufacturer as Walker. Once the product comes up, select the drop down box and you will see them priced at $25.79. This same muffler sells for $46.95 at Summit Racing.
