Invidia Gemini Single Layer Cat Back Exhaust w/ Stainless Steel Tips - 2015-2021 Subaru WRX / STI

The Gemini : Quad Tips, Track Character, Street Fitment

The Invidia Gemini Cat-Back Exhaust with Stainless Steel Quad Tips for the 2015-2021 Subaru WRX / STI is the multi-tip option in the Invidia lineup. Four Stainless Steel tips exit at the rear of the VA WRX/STI in the Gemini configuration, giving the car an aggressive rear presentation that single-exit systems can't match. SUS304 stainless construction, mandrel-bent piping, CNC-machined flanges, direct OEM hanger fitment.

Quad Tip Gemini Configuration — The Rear End Statement

The Gemini quad-tip layout is a visual choice as much as a performance one — four exhaust outlets give the rear of the VA WRX/STI a wider, more finished appearance. The Gemini uses SUS304 stainless steel mandrel-bent piping throughout, maintaining full internal diameter at every bend. CNC-machined flanges provide flat, leak-free sealing at every connection point.

OEM Hanger Fitment, Complete Hardware

The Gemini bolts directly to the OEM downpipe flange and hanger positions on the VA WRX/STI — no modification required. New gaskets and hardware are included. The quad-tip exit sits at the factory tip cutout location for a clean, factory-integrated appearance.
