AFE 49T30401-H151 This direct-fit clamp-on tip is constructed from stainless steel for corrosion resistance and long lasting good looks. Over the years, most auto manufacturers has done a relatively good job of designing the factory system to support the factory power levels and create a system that would suit the masses in terms of aesthetics and sound level. That being said, there are numerous reasons to make the upgrade to a higher flowing, performance exhaust kit on your Chevy Duramax. In general, you can expect an increase in power, a bump in fuel economy, lower EGT's (Exhaust Gas Temperatures), and of course, a sweet new sound
