Overview

Carefully engineered, it offers an excellent way to experience improved vehicle performance.
Show original supplier description
Constructed from T304 stainless steel, it features a 2.99" (76 mm) diameter piping and a high-flow catalytic converter, designed to increase horsepower and torque without sacrificing low-end power. This down-pipe is built with utmost care and attention to detail, providing unmatched durability and strength even in extreme operating conditions. Invidia is known for manufacturing reliable parts that operate at maximum performance levels for extended periods. The quality stainless steel construction ensures rigidity, strength, and resistance to corrosion for long-term service. Applications include the 2015-2021 Subaru WRX with a Manual Transmission (MT only). Installation may require new studs, especially in high rust areas, and some users recommend using penetrating oil on turbo stud bolts. While designed to avoid O2 sensor codes, some users have reported experiencing them, suggesting that an open-source tune may be necessary for optimal performance and code management.

Shipping

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.

Free shipping over $200 in the continental US. 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.
