I never see MRT's axle back exhaust mentioned in anyone's 'signature'. Are these mufflers the best kept secret of the '05/'06 performance mods? I had considered all of the nationally advertised brands, and had decided to go with the Magnaflows. They were Stainless, and had a great sound. I was ordering them from MRT, when I was told about about their in-house designed system. I took a chance and was impressed with the quality look and sound. I'm familiar with most of the popular setups and am glad I went with the MRTs. I can't be the only one out here that is using them. If you are looking for a system, consider these highly polished 304-stainless beauties!
