HKS 05-08 tC Hi-Power Rear Muffler

If you're looking to change up the sound of your 2005-2008 Scion tC, this HKS Hi-Power rear muffler is a solid option. It's designed to replace the factory muffler, giving your car a more aggressive exhaust note that's noticeable without being over the top. This part is specifically for the rear muffler section of the exhaust system, often referred to as a cat-back system when paired with other components.

HKS has built a reputation for making well-made exhaust components, and this Hi-Power muffler is no exception. It's constructed from SUS304 stainless steel, which is known for its strength and resistance to corrosion, meaning it should hold up well over time. The muffler features a large-diameter, straight-through core design. This design helps to reduce backpressure compared to the stock muffler, which can lead to a slightly improved throttle response and a deeper, sportier exhaust tone. The canister itself is a generous size, which helps to pack in sound-dampening material for a balanced sound profile.

When installing this muffler, you'll find it's designed as a direct replacement for the factory unit. This means it should bolt up to the existing exhaust hangers and connect to the factory mid-pipe or an aftermarket cat-back system designed to mate with the stock location. While this is just the rear muffler, it's a popular choice for tC owners looking for a noticeable change in their car's sound. You might consider pairing it with other exhaust upgrades down the line if you're aiming for a more complete system, but on its own, it offers a distinct improvement in exhaust character.
