Whether you like it loud or quiet, it's important to have a top-grade muffler on your exhaust system. Minimizing noise for neighborhood driving with a large muffler or maximizing the rumble for growling around the track with a small muffler, don't end up on the opposite end of the spectrum due to a busted part. Find a replacement for your cracked or worn-out muffler at AutoZone and get back into the decibel range you prefer.

Swapping out your muffler before it deteriorates not only revives your exhaust system, but also improves your vehicle's performance. An easy way to determine a problem with your muffler is noticing decreases in your fuel economy and engine power. With a malfunctioning muffler, you may also notice a rough idle and a rattle, hiss or roaring sound coming from the rear of your exhaust. If your muffler is covered in grime or is suffering from rust-causing perforation, it can also be time for a replacement. Make sure your exhaust system is up to your sound standards with a new muffler from AutoZone.
