Deciding between an axleback and midpipe for your Toyota 86? We compare the sound, power, and fitment tradeoffs to help you choose the best first upgrade.

Quick answer

Start with the axleback if you want the most aggressive sound and a budget-friendly first mod. Add the midpipe later for more flow, torque, and a complete catback experience.

Sound character: Axleback vs midpipe

The axleback is the primary source of volume and tone. The REMARK Axleback (BOSO Edition) delivers a very loud, aggressive note inspired by Japanese Bōsōzoku style. If you want maximum exterior presence with a deep, raw tone, this is your starting point.

Adding a midpipe after the axleback increases flow and refines the exhaust note, adding a deeper roar without making it overwhelmingly louder. It also removes the factory donut gasket, which can improve sound consistency.

Power and torque: What each part contributes

An axleback alone frees up some restriction, but the midpipe is where you unlock more flow, power, and torque. The REMARK Midpipe Kit is designed to bolt directly onto the axleback, completing the catback system. For noticeable mid-range gains, the midpipe is essential.

If you only install the midpipe without an axleback, you'll see modest flow improvements but the sound will remain close to stock. The pairing is what delivers the full performance benefit.

Installation and fitment considerations

Both parts are direct bolt-on for 2013-2021 Scion FR-S, Subaru BRZ, and Toyota 86. The axleback is a simpler install and can be done on jack stands. The midpipe requires a bit more space and care, especially removing the factory donut gasket.

REMARK does not recommend using aftermarket adapters with the midpipe, as they may cause incorrect fitment. Stick with the supplied hardware for a leak-free seal.

Tradeoffs at a glance

Start with axleback: Install the axleback first for the loudest, most aggressive tone and a budget-friendly upgrade (around $361). You get immediate sound satisfaction and a unique Bōsōzoku-inspired look. Best for owners who prioritize sound and want a quick, affordable mod.
Add midpipe later: After the axleback, add the midpipe ($424) to increase flow, torque, and power. It bolts directly to the axleback and removes the factory donut gasket, completing the catback system. Plan to pair both for full performance gains.
Start with midpipe alone: Installing only the midpipe improves flow modestly but keeps the stock muffler, so sound stays close to factory. You won't get the volume or aggressive note most 86 owners want. Skip this approach unless you plan to add an axleback soon.
