Selling a complete Invidia Q300 cat-back system for any 2015-2021 WRX or STI. The system was ordered late January of 2026, and installed early March, 2026. It was used for less than 500 miles due to trading in the STI(2016) for a Golf R. The Invidia Q300 is probably one of the best cat-back system for any 2015-2021 WRX/STI. It does not give you any type of drone in any speeds(local or highway). It does give a nice Subie Rumble for sure! We installed stock exhaust back on before the trade. That's why we are selling it. We paid $1700 including tax in January 2026 with receipt.

All parts are in like new condition. Will come all as shown in pics.
Will come with all original hardware AND the donut adapter(paid $72 extra from FastWRX.com) which you will need to install onto your car(2015-2021 WRX or STI).

Part number: Invidia Wrx/Sti 4 Door Q300 Rolled S.S. Tips Cat-Back Exhaust System #HS15STIG3S

Local pickup only. Asking for $1,500 cash. Will accept reasonable offer. show contact info
