All Stainless Steel is the same, right? WRONG!
All Rogue Engineering Diablo exhaust are produced using only 100% full T-304 stainless steel because of its consistent strength characteristics, corrosion resistance, and wide range of materials (important for controlling sound and exhaust flow). Recently, we examined a well known exhaust brand only to discover the use of 20 gauge stainless steel (stainless is typically sold by weight) throughout the muffler body. While great for reducing weight, this is not a good practice when trying to build a product to last. This common practice of weight (and cost) savings occurs in European and US made exhausts. Rogue Engineering does not prescribe to this practice in their production exhausts! We want you to enjoy the exhausts for many years to come, even if it means sacrificing some weight savings (all Rogue Engineering exhausts are lighter than stock units).
Beware of some companies that pre-coat their exhaust products with "thermal coatings". In fact, they may be hiding inferior stainless steel or inferior welding processes. Rogue Engineering Diablo exhausts are always TIG welded and never coated.
Some companies have chosen to build their "stainless steel" exhausts with Grade 409 stainless, because it is less expensive than 304. While Grade 409 will resist atmospheric and exhaust gas corrosion, a light surface rust will form is most all atmospheres.
