If you’re unfamiliar with STS’ remote turbo systems, you can be forgiven just this one time. STS’ turbo kits have been popular with domestic muscle and trucks for years but haven’t made a huge impact on the import scene yet. The unique thing about STS’ kits is that they mount the turbocharger in the back of the car, usually where the muffler previously sat. The long turbo pipes serve to cool the air without needing an intercooler and the turbo actually muffles the exhaust sound pretty well.
The best part, at least for the Scion FR-S and Subaru BRZ STS rear mounted turbo kits? The sound. Turbo FR-S and BRZ cars usually sound great, but the remote turbo STS kit sounds like a space ship with its high pitched whistle.
