The February 2020 Edition of Japanese Performance magazine features a comparison between two second generation Subaru Imprezas, one of which is a WRX and the other is a WRX STI.
The latter of the pair is equipped with a Cobra Sport Turbo-Back performance exhaust system.
"Down in the engine room, he treated the Scoob to a Cobra turbo-back exhaust system and K&N induction, got it mapped, and that was that."The article highlights just how different two comparably very similar cars (standard) can end up based on the respective owner's taste."
Japanese Performance is available in many major retail outlets.
