Review on Gibson 788700 Superflow Performance Muffler by Leeboi Portillo

Our team upgraded OUR automotive exhaust system with this muffler and the results were impressive. Using this product, our team found that it greatly improved our cars airflow boosting its performance .The sound is deep and throaty, but not too loud. The only con is that installation can be a bit tricky if you're not mechanically inclined. Overall, we highly recommend this product for any automotive enthusiasts looking for a powerful upgrade..
