Exceeded expectations by far. This muffler was added to a straight pipe exhaust. A 4"down tube feeds a 5" system with a 7" tip at the end. The first thing observed was that the warm up valve noise was greatly reduced. Other benefits were a much more tuned sound that is easier to live with, and no longer having to shut the truck off to order at a drive thru. The presence of sound with 5" is awesome but, this muffler made it even better. One last detail that I appreciate is that the EGTs haven't changed. Great product! Thank you Spin Tech!
