Thoroughbred Sku #: DEMMUFFLER
Year/Make/Model: {{year}} {{make.Name}} {{model.Name}} Edit
Aluminized or Stainless mufflers available in perforated, louvered or big dog quiet tone styles. Thoroughbred Diesel offers both 4 inch as well as 5 inch Diamond Eye mufflers.
The diamond eye mufflers will work.
Of the two choices on that page, the louvered will be the quietest muffler as per the manufacturer. There is a muffler they offer that is not on site that is a “Quiet Tone” louvered and it is their quietest option.
