Based on our own experience this muffler was a complete disappointment. It failed to increase performance, and the sound was ear-piercingly loud. The only pro is that it was easy to install. However, the CONS outweigh the pros, and we do not recommend this product..
I am very happy with this purchase. I already had the glass package on my 01 Silverado but it was removed, this brought back the nice rumble I had and then some.
Pros
SINGLE STAGE SEAL – The single stage seal configuration in this muffler is designed so that the classic sound of insulating glass is heard throughout. Check local noise regulations
