While most exhaust tips are added for visual appeal, some exhaust tips added to vehicles to alter the sound profile of the exhaust system. Exhaust tips are attached to the tailpipe by clamps, screws, bolts or welds. The tip design determines the effect on the sound profile of the engine.
Exhaust tips are primarily attached to vehicles to alter the style or looks of the vehicle. Metal types do not noticeably affect the sound profile of the exhaust system.
The exhaust tip's design of shape and construction will directly affect the sound profile of the exhaust. Exhaust tips that increase in diameter or are beveled or flared will likely amplify the exhaust. Tips that are dual-walled are constructed of two sheets of metal of different diameters connected at both ends of the exhaust tip. Dual-walled tips appear to add more bulk, and may also increase the resonance of the exhaust sound as a result of the chambered tip. To keep the exhaust sound similar to the existing system, select an exhaust tip that is designed to slide over the existing tailpipe and of similar diameter.
Chrome exhaust tips that contain sound dampening linings are referred to as "resonated tips." Resonated tips are lined with fiberglass or other sound absorbing materials and are usually installed to reduce the sound output of the vehicle.
There is no notable difference between chrome and stainless steel exhaust sounds of the same design. The primary difference in metals is the corrosion resistance found with stainless steel. Additionally, less maintenance is required to keep a high level of shine with stainless steel. Stainless steel usually is more expensive.
