Powerful Sound Boost with Walker Exhaust Resonator

As a result of my tests I determined that the resonator assembly gave my car a deeper and more powerful EXHAUST note without any annoying drone. The installation was a breeze and the resonator seemed well made and durable. However, the price was a bit high compared to other similar products in the market. .

Pros
  • Improves engine performance by enhancing exhaust flow and reducing backpressure.
Cons
  • Requires professional installation, which can be costly.

Seam leak on replacement parts

The new muffler was leaking at the seam and I had to strip and weld the seam. Too bad Walker has such poor quality control. It doesn't look like this was an isolated case as a couple of weeks later I bought a second one from a local auto parts store and had the same problem (seam leaking) just a different seam. Once again I had to shoot to weld.

Pros
  • Excellent design
Cons
  • Not the best
