Exhaust tips are added to the tailpipe of a vehicle's exhaust system. The exhaust tip provides styling and may be added to alter the sound profile of the exhaust. Oval exhaust tips are available primarily in two metal types (stainless steel and chrome), can be installed with minimal tools and can be purchased in styles which either amplify or reduce the exhaust system's sound output.
Oval exhaust tips are available primarily in three types of installation connections. Clamp-on tips have a clamp installed at the intake of the tip. The clamp is either free floating or welded to the intake of the exhaust tip (welded clamps are more durable). The exhaust tip is placed onto the tailpipe, as a sleeve, and the clamp is tightened until the exhaust tip is secure. Bolt-on tips have a screw or bolt that is tightened against or into the tailpipe to secure the exhaust tip in place. Weld-on tips are either slid over the tailpipe like a sleeve and welded to secure the placement or the tailpipe is cut and the exhaust tip is welded to the end of the pipe.
Oval exhaust tips alone do not alter the sound profile of the exhaust significantly. Oval tips are available as resonated or non-resonated tips. Resonated tips have a fiberglass lining or sound dampening material that lines the interior of the tip. The lining reduces the sound output by absorbing sound waves. Non-resonated tips do not have any sound dampening properties. If the tip is dual-walled, beveled or has a flare, the exhaust sounds may be amplified.
Oval tips are available primarily in stainless steel and chrome. While chrome is generally less expensive, stainless steel exhaust tips may last up to five times longer. Stainless steel is also more resistant to the corrosive effects of road debris, weather, exhaust gasses and oils. Stainless steel's durability also results in less overall maintenance to ensure a high shine.
