For those EVO Enthusiasts where exhaust quietness is a strong consideration, the StealthWORKS muffler is your answer. The original design is fairly complex (see image below) with room to improve airflow without sacrificing sound suppression. We take the stock EVO muffler and modify it in-house to produce the most power with the least noise. We cut open the canister, modify the internals for a more direct, unobstructed flow, re-weld with stainless steel wire and repaint the canister to a factory black finish. Voila, you have a muffler that looks stock, sounds almost stock, fits perfectly, provides quicker turbo spool and produces more power and torque. The gains may not be as impressive as with the upcoming Exhale AB/ABM, but worth the sound reduction if you're not looking for extra attention. The StealthWORKS muffler is 100% compatible with the stock Intermediate Pipe. Complete with simple installation instructions. Combine our muffler with the WORKS High-Flow Drop-In Air Filter for even more performance gains.

The StealthWORKS Muffler is sold on a core-exchange basis. We offer two options; You can send in your core once you place your order and we will send your new StealthWORKS Muffler once we receive and inspect your core. Or we can charge $300.00 onto your credit card and ship your new StealthWORKS immediately. Once we receive your old core (in good condition with less than 30,000 miles), we will credit your card for the full amount. This is convenient as you do not need to have your EVO down for an extended period of time.
