Fantastic muffler, very good quality and very durable, put it on my 3.9 liter Dodge Dakota 89 V6 truck. I took it to work two days after I put it on and all my efforts, the workers were amazed by the noise. it's not too loud and not too correct, just how I wanted it. When I rev the engine and listen from behind it sounds like a V8 truck. cool, so happy and for the price you can't go wrong. I bought it used from Revain inventory and it only cost me $30 with free shipping, what more could you ask
