Show original supplier description
The MAPerformance catback exhaust system offers a direct-fit upgrade for 2015-2021 Subaru WRX and WRX STI vehicles, replacing the restrictive factory piping to optimize exhaust flow. Built for long-term durability, the system features mandrel-bent 3-inch and 2.5-inch 304 stainless steel construction. It includes twin polished 304SS mufflers, dual resonators, and dual staggered 3.5-inch dual-wall 304 tips. The entire assembly is TIG-welded and USA-made to withstand harsh conditions without rusting. Please note that this catback system does NOT fit the SPT exhaust configuration. All necessary installation hardware and clamps are included with the kit, and the system now utilizes a clamp-on tip design rather than welded-on tips to ensure proper alignment. A limited lifetime warranty is included to provide long-term peace of mind.

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
