Took my 03 Ram 4.7L to Zoro Muffler on Centennial Parkway in Hamilton for the typical Dodge manifold leak. Was quoted $600-700 for driver's side only, final price came in under the quote at $540 (tax in) and it was finished in under 2 hours. Nice and quiet now.
Been going there since my first car over 20 years ago, have always had great service, fast, quality work.
They do custom work, mandrel bent stainless, etc. for those of us who need solutions that are not "off the shelf".
