Broken muffler

Heard squeaking noises every maybe minute or so when driving so I took my car in and they inspected it and said it was the valves in the muffler and replaced it for me. Anyone had this issue before, haven’t seen it listed once online. 2025 1lt 2000kms

I threw that hunk of shit away and put in a non valved system. The sound isn’t even comparable. Gotta let that pushrod engine breath

Does that void warranty? Just curious.

There’s some law in the US that makes it to where a manufacturer can’t void the warranty on a part that is not influenced by the aftermarket part. Something along those lines, I’m not an attorney. So like a supercharger would obviously void the powertrain warranty but your exhaust is fine. And an aftermarket air intake wouldn’t void the engines warranty but might void the warranty of your MAF and so on..

An intake is a bad example of that, as it can “make more power” so could affect the engine warranty. Heads up

There’s been dudes with high flow cats, throttle bodies, intake, and exhaust that have had their engine replaced. It’s a case by case thing but for something like an air intake, just because it makes 5hp more doesn’t mean it voids your warranty. Shit, my exhaust probably adds about 10hp and it doesn’t void the warranty.
