This catted downpipe serves the K-series engines in the 2009-2014 Acura TSX and 2008-2012 Honda Accord, pairing with a header to replace the restrictive factory catalyst section. The high-flow catalytic converter keeps exhaust chemistry in check while flowing far better than the dense stock unit, which translates to freer revving, a stronger pull through the midrange and a cleaner, sportier exhaust note.
K24-powered sedans respond well to breathing work, and this piece is the crucial link between a header and the cat-back: skip it and the header's gains die at the stock converter. Fitment is specific to these chassis and years, so double-check your model before ordering. Install with fresh gaskets, torque in sequence, and finish with a tune to collect the full benefit.
Shipping
Everything ships from a United States warehouse. Orders normally leave within 1 to 3 business days of clearing, and you get a tracking number by email the moment the shipment is created. Orders over $199 ship free. Below that a flat rate is calculated at checkout before you pay.
Wheel and tire packages ship mounted and balanced on a pallet or in individual boxes depending on size, and take a day or two longer to leave because they are assembled to order.
Returns
Unmounted and uninstalled parts in original packaging can be returned within 30 days of delivery. Start a return by emailing us the order number and we will send a return authorisation and instructions.
Two things cannot be returned, and it is worth knowing why before you order. A wheel that has had a tire mounted on it is marked by the machine and is no longer new. A tire that has been fitted to a wheel has been stretched over a rim and cannot be certified as unused. Both are industry standard. It is also the reason we check the fitment data on every order against the vehicle you give us and contact you before shipping if something does not add up.
Damaged or wrong item
If something arrives damaged or is not what the order says, tell us within 48 hours with photographs and we cover the return shipping and put it right. That is on us, not on you.
