This BLOX Racing muffler delete kit is made for 2015–2021 Subaru WRX and WRX STI models and replaces the factory muffler with a straight-through section where the muffler once sat. It’s a direct-fit kit created for those specific model years and body variants. The delete changes the rear exhaust path to provide a more unobstructed flow and a louder, less muffled exhaust character for owners seeking a more aggressive sound and simpler rear exhaust routing.
