What is the difference between T304 Stainless Steel and T409 Stainless Steel?

T304 stainless steel will not oxidize or rust. It can develop a golden color when exposed to high heat over time. T409 stainless steel has a small amount of ferrous material in it and can show surface rust after some time, especially when exposed to road salt. If you are concerned about long-term appearance, you should purchase a system made of T304 stainless steel. If you are more concerned about the price, but want something that is more durable than aluminized steel, then a system made of T409 stainless steel should be a consideration.

What improvements can I expect in performance?

While performance gains vary depending on the vehicle, you can expect a gain of 2% to 10% in horsepower and torque. For example, with a 2005 Chevrolet Silverado with a Duramax diesel engine you will see a gain of 18 HP. and 28 ft/lbs measured at the rear wheels. Most flow improvements fall between 20% to 100%. You can also expect a reduction in exhaust gas temperature (EGT) by approximately 200 degrees Fahrenheit.
