951 S

Spent a bit of time trying to figure out why my car was not passing emissons. Thought I had a real cat by looks of the construcution but upon removing to inspect I found it was hollow with a glass pack style muffler inside. Pretty tricky, who makes this unit?

Typical bypass muffler. The make with and without muffling material.

You need a nice new 200 cell performance cat.

Ahhh. never seen one with muffling & construction similar to oem cat, only seen straight pipe versions that stand out.
