Research on Muffler for Pontiac Grand Prix

Pontiac Grand Prix Muffler

No one likes to listen to someone else’s engine noise drowning out the satellite radio at a stop sign, and no one wants to be the neighbor whose noisy car announces the arrival home. Your Pontiac Grand Prix may have a powerful engine, but its style is only as good as its ability to minimize the sound output. A good muffler can keep you from embarrassing situations involving engine noise.

At PartsGeek.com, we stock mufflers for the Pontiac Grand Prix year models 1971 all the way through 2007, from manufacturers such as Flowmaster and Walker. Take advantage of our 30-day money back guarantee if the part you buy is not the part you need.

What is a Pontiac Grand Prix muffler?

The muffler is part of the exhaust system that pulls the exhaust away from the engine and releases it out the exhaust pipe. The muffler also keeps the engine noise from your Pontiac Grand Prix to a minimum. The tubes inside the muffler reflect sound waves so that they cancel each other out, significantly dampening the sound output.

How much is a Pontiac Grand Prix muffler?

At PartsGeek.com, a Pontiac Grand Prix muffler costs between $50 and $115. Prices vary based on select features and your car’s year model and engine size.

What causes a muffler to deteriorate?

Condensation that collects inside the muffler from the exhaust or precipitous weather such as snow or rain can cause the muffler to rust over time, weakening and producing holes in it. Your Pontiac Grand Prix’s muffler can also be damaged by potholes or by rocks and road debris that bounce and hit the undercarriage of your car where the muffler is located.

How do you know it is time to replace your muffler?

The most obvious sign that your muffler is not doing its job is that your car will produce much more noise than usual when the engine is running. There are also visible signs that your muffler may need to be replaced:

  • Noticeable holes or rust
  • Water leaking from multiple places on the muffler
  • Significantly higher reading on temperature gauge

Very Satisfied
Reviewer: 2004 Grand Prix Walker Exhaust Review`

I was an Walker exhaust engineer for my first after college job. The exhaust fit PERFECT. I am fortunate to have access to a hoist so the installation was easier. After removing the OEm system the Walker system took 35 minutes to preset align and tighten down. Very Highly recommended.
