Car mufflers and truck mufflers are often different. Many cars, but not all, have mufflers that are right at the tail of the exhaust system. For these, the muffler tip is a part of the actual muffler. When shopping through our Cadillac Seville muffler selection, keep that in mind, as most mufflers are actually listed as universal mufflers. Some of the most popular mufflers are Flowmaster mufflers and Magnaflow mufflers. If you have any questions about mufflers for your Cadillac Seville, or if you are having trouble finding a Cadillac Seville muffler on our website, please contact us.
