🔊 Jones Exhaust U4-4: Premium Performance Muffler for Superior Sound Control Review

Through trial and error, I found that this replacement part was not suitable for automotive use. The pros were that it was easy to install, but the cons were that it emitted excessive emissions and was extremely loud. I would not recommend this product for anyone in need of a reliable automotive replacement part.

They said the center was about 6 inches but it was actually about 4 3/4 - 5, had to cut it and fit it, quality is good, just not that big

Don't think that this Y-tube is 6 inches center-to-center on the side of the two outlet tubes. There is a reason why the seller did not specify the product's characteristics in the description. This Y was 5.25 inches center to center. Very disappointing when you put it on a twin pipe intake muffler which almost always measures 6 inches center to center and my muffler is like that. socks to try to bend the Y to 6 inches. Dissatisfied buyer.
