Aero Exhaust's Stealth mufflers are similar to the Magnaflow and the Borla XL in design. Constructed out of 409 stainless steel for optimum corrosion resistance and wear, Stealth mufflers are polished to a high luster finish. The internals include ultra high temperature ceramic sound absorbent material with unsurpassed heat resistance. Ceramic packing is rated up to 3000 ºF making it more durable than fiberglass, and more resistant to break down, a common problem with fiberglass packed mufflers. With numerous internal tube configurations, installers can choose the tone that is right for them. Stealth mufflers feature fully welded joints with double overlap impact resistant end caps and are fully reversible.

These high performance mufflers are ideal for automotive enthusiasts who want increased performance with near stock sound levels. Stealth mufflers are a great addition in both car and truck applications.

The 163 is a single inlet dual outlet muffler which provides a great option for performance cars and smaller trucks and SUVs. It can be used to build a dual 2'' system on the trucks and SUVs or used as a dual outlet muffler on the performance cars. The 163 has a medium throaty performance sound.
