Mufflers and pipes do wear out.
Sometimes our prices for exhaust are the same as the discount muffler shops, other times they can be a good bit higher. It depends on the vehicle and the parts you need. They usually use generic or economy parts, or straight pipes, and custom bend them in the shop. This does keep the cost down, but often the quality or thickness is less. Most of the competition' s warranties (whether "lifetime" or not) do not cover labor.
We use only high quality OEM- factory fit parts that we expect to last, but if they don't our Amazing Warranty covers parts and labor. There are no tricks or hidden charges. If your muffler or pipe gets a hole in it 3 or 10 years from now, we'll put on another one!
