Thanks for the replies. Cost is a factor. I'd rather not spend more money than I have to. I am pretty sure my exhaust system is all original. So that means it lasted 14 years and 152,000 miles. I am pretty sure my muffler is the culprit. I have a pretty good rattle coming from the muffler area. When I'm driving it sounds like it's in the back seat. Is there a better quality muffler available that will simply replace the OEM one? Thanks again.
