This muffler its just what I was looking for, the performance of a flowmaster and the sound of a super car.

I put this on my GMC JIMMY vortec 4.3 V6....I was amazed how mellow and aggresive it sounds. It sounds like a small block 350. Everywhere I go I get heads turned and questions asked. Not too loud outside and very quiet inside. and at idle sounds GREAT!
