Axle-Back Exhaust Systems

An axle-back is the fastest way to give a car a real voice: it replaces only the section behind the rear axle, installs in a driveway afternoon with basic tools, and leaves all emissions equipment untouched. This collection covers axle-back systems and muffler deletes across the platforms that sound best with them.
Subaru WRX and STI owners are the regulars here, with 2015-2021 systems and muffler deletes in multiple tip finishes that unlock the boxer rumble. Muscle fans get stainless deletes for the 2016-2023 Camaro SS and ZL1, 2.5 inch dual kits for the 2005-2010 Mustang GT, and systems for the Charger and Challenger SRT and Hellcat. Hot hatch and sport compact fitments, including the Elantra GT, round out the range.
Construction is mandrel-bent stainless steel with TIG-welded joints, so the sound you buy is the sound you keep. If you want a deeper change in character, step up to the complete exhaust systems, or start the chain at a downpipe on turbo cars. Compare tone options within the full exhaust range before you commit.

Axle-Back Exhaust Systems: the questions people ask

How do I know this fits my vehicle?

On hardware the measurements matter more than the vehicle list: thread pitch and seat type for lug nuts, bolt pattern and hub bore for spacers. Where a listing says universal fitment it means the part is not cut for one specific vehicle, so the dimensions are the whole answer.

What quantity does a listing cover?

Whatever the title and specification table state. Hardware is often sold in sets that cover one wheel rather than all four, so check before ordering.

How fast do orders ship?

Orders ship from a United States warehouse, normally within 1 to 3 business days of clearing. Orders over $199 ship free, and below that a flat rate is shown at checkout before you pay. Tracking is emailed as soon as the shipment is created.

What can I return?

Unmounted, uninstalled parts in original packaging can be returned within 30 days. A wheel that has had a tire mounted on it, and a tire that has been fitted, cannot be returned because neither is new any more. That is why we check the fitment data on every order against the vehicle you give us before it ships.

Can someone check fitment for me before I order?

Yes, and it costs nothing. Send us the year, make, model, trim and what is on the vehicle now, and we will tell you what fits, what will rub and what it takes to clear.
