Great system. Had it welded on for max performance would suggest to do this as well. You don't have to though

I like my Flowmaster 50 series muffler but i wish I would have gotten a 70 series Flowmaster for less noise, I do not mind a little noise in back of the car but cabin noise bugs me, as they say after the fact. It would be nice if there was a return policy if we the customer was not happy and was going to exchange for a similar product.
