Important Exhaust System Features

There are a lot of excellent exhaust systems on the market that can replace the factory one. In an effort to determine your choice of which exhaust system you should invest in for your Dodge Ram 1500 HEMI, take into account the following important exhaust system features.

Quality Construction – the typical aftermarket exhaust system is constructed of stainless steel with four basic finishes:
• Nickel Chrome – has nice shiny surfaces, with better anti-corrosion resistance, but known to discolor easily
• Silver Ceramic – corrosion and heat resistant
• Titanium Ceramic Coated – good heat and corrosion resistance and helps reduce heat buildup under the hood
• 409 Stainless Steel – the most durable type but also know to discolor easily

Pipe and Tip Diameters – larger diameter pipes allow exhaust gases to flow with less restriction, which in turn makes it easier for your HEMI to “breathe”. This will equate to improved engine performance and better fuel mileage. The pipes should have a minimum diameter of 2.5-inches, but 3-inch pipes would be even better. The size of the tip diameter has a profound affect on sound of the exhaust. The wider the tip, the better the sound. You should settle for nothing less than a 4-5 inch tip diameter.
