You could have a aftermarket muffler. But I would get it checked out.

You should have the engine inspected to make sure all is ok. It could be that your muffler is bad.

Hi Richard
Ya had it checked out and it's going to b e needing one but it is all right for right now! Another question comes to mind ,I am thinking about dual exhaust,what all does that in tail to change it to duels? I know that it isn't as simple as it use to be back when I was a kid,all ya had to do was slap on the headers and run the tail pipe, I guess that you have to do something with the electronics and the computer system now,at lease I still know how to change the oil and grease the car and but air in the tires,god now that I am retired i want to get back into working on my own cars but man I am lost,and I use to love it so,you wouldn't believe some of the old cars I use to build with my buddies from the ground up,think I'll visit the library and start reading up on building one,here in New Mexico we don't have to worry about all the air standards like you do in other parts of the country,I think this is a good thing,

On that car dual exhaust will be easy. There is alread two cats and sets of sensors. It's just cutting off the muffler and putting new stuff on.

Car Brakes: How Do You Know When to Change Them?

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
