Aftermarket Exhaust Systems & Accessories

This collection gathers complete exhaust systems and the accessories that support them: cat-back and axle-back kits, mid pipes and Y-pipes, crossover pipes, race bypass pipes and full titanium systems. Where the headers section handles the front of the exhaust, this is everything from the midpoint back, the parts that define how your car sounds on the street.
Fitment coverage is wide and genuinely interesting: Subaru WRX and STI, Civic Type R FK8 and FL5, BMW G80 M3 and G82 M4, Camaro SS and ZL1, Mustang GT, Charger and Challenger Hellcat, Infiniti Q50 and Q60, Nissan 370Z, and even Can-Am Maverick X3 powersports machines. Materials range from mandrel-bent stainless steel to weight-saving titanium with burnt tips.
If you only want the rear section, go straight to axle-back exhaust systems. Turbo car? Start with a downpipe for real gains, then match the system. And for the lightest option on the shelf, browse the Titanium Series. Every system lists chassis, years and engine so the sound you order is the sound that fits.

Aftermarket Exhaust Systems & Accessories: 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.
