Is stock muffler covered by lifetime warranty?
 

my 2005 ppw enthusiast has a bad rattle coming from inside the muffler at cold starts that is progressively getting worse. i suppose the insides of the muffler are coming apart.

the car has 28k miles should this be covered by nissan?
thanks

You really aren't giving much information here... and the only definite answer you will get will be found in the looking through your warranty paperwork and/or calling the dealership. If your car is still covered under a bumper to bumper warranty, then the muffler probably will be covered... if you only have a drivetrain warranty remaining, then it probably won't be covered.

Nothing is covered under lifetime warranty except for the interfooler.

Probably not. Here's what the warranty manual says...

That appears to be a warranty for OEM replacement parts that come with Lifetime Warranty. It's like when you go to a parts store and buy brakes, you can get the cheap ones with the one year warranty (normal OEM replacement parts) or you can pay more and get the one with the lifetime warranty (special OEM replacement parts such as this muffler).

Later in the manual this setcion can be found...

Those are probably the "cheap" ones you get as part of the normal OEM replacements.

All of this is described in a special section in the back of the manual, outside the normal 3yr/36K mile section that covers the full car.

No certain. What does your warranty say?

just buy a used nismo cat back and call it a day.

I had a similar problem awhile back. I had some janky high flow cats and the catalyst broke up and I guess was pushed back into my muffler. I got test pipes, a Nismo S-Tune exhaust, and called it a day.

Always happy to help. If you have other questions please do not hesitate to waste my time.
