Due to its dense concentration, stainless steel exhausts produce a deeper and fuller sound. The ability to resist corrosion and staining, along with low maintenance and attractive glistering makes it an ideal material to use. Though T304 has good corrosion resistance characteristics, it is not guaranteed to prevent corrosion. If you live near salt water or in a snowy area, it is advised to enquire for an optional coating to fully prevent corrosion.
Upgrading to an Stainless Steel system will save a lot of weight over the bulky stock exhaust. The T304 stainless steel is a considerable upgrade over its factory counterpart.
