Koauto Exhaust Muffler Silencer Insulator Review

This automotive part was a total letdown. Through trial and error, I found that it barely made a dent in reducing noise despite its claims. The only pro was that it was easy to install .However, the cons are that it didn't PROVIDE the desired effect and it was a waste of money. Save yourself the trouble and find another option..

Excellent price for 4 pieces. Most cars only use 2 pieces of this style and a few pieces of another style. Give your mechanic the extra 2, he'll appreciate it!
