With the Kizashi being 10+ years old , here in the high salt use area , I’m seeing alot of muffler rust out that legally must be rejected for state inspection . Some customers are fine with going the cheap route and eliminating one or both of the rear mufflers with pipe. This is legal because only 1 muffler is required and the front hasn’t failed on any yet. However , some customers want to keep the car sounding quite as it once was. The cost of just 1 of the rear mufflers is over $800. I found a universal muffler that was a perfect weld in unit that sadly was being discontinued but may be copied by other exhaust manufacturers

.

It fit perfectly and was less than $40. The sound was pretty much the same as the original. Your auto parts supplier may be able to find an equal by the part number. Walker 17908
