The converter that fits your VIN — and passes in your state.
Direct-fit and universal catalytic converters with the Executive Order number printed on the label. Next-day everywhere, same day across greater Los Angeles. One part or twenty.
A VIN returns the exact converter for your engine family — position, flange, and O2 bungs included. No guessing at sub-models.
Next-day delivery on everything in the Los Angeles warehouse
Guaranteed fitment — wrong part, we pay the return
EO on file for every California-legal converter
Your state decides the part.
California follows California's rules: an aftermarket converter needs a CARB Executive Order that names your engine family, stamped on the shell. Parts without one are hidden from your results entirely.
An EO looks like D-724-10: the letter marks the part family, the middle number is the approval, and the trailing revision grows as more engine families are added.
What we stock.
Bolt-in, OE flanges, correct sensor bungs. 47,000 fitments across 66 makes.
Weld-in bodies, 2.00 to 3.00 inch, for pre-OBDII and custom exhaust work.
Anti-theft cages, O2 sensors, gaskets and hangers — shipped in the same box.
Start where you are.
Three ways people land here. Each one pre-fills the search and skips what you do not need.

We only show parts that will pass where the vehicle is registered. Federal-only converters stay hidden in CARB states.
You are getting a lot ready to sell
Paste up to fifty VINs, get one quote with volume pricing, and ship everything to the recon bay in a single delivery.
Volume pricing without an application.
There is no dealer portal and no second login. Add four or more of the same converter and the trade price applies in the cart — for a body shop, a recon center, or one person buying for the whole family.
Reseller and tax-exempt IDs go in once at checkout and stay on the account. Net-30 opens after your third order.
Questions people actually ask.
What is a core charge?
A refundable deposit on the precious metals in your old converter. Ship the old unit back with the prepaid label in the box and the deposit returns to your card within three business days.
Will my station accept this part?
In CARB states we only sell converters with an Executive Order covering your engine family. The EO is stamped on the shell and listed on your invoice.
I cannot install this myself.
Ship it to a verified installer. We hold the appointment, send the EO paperwork to their bay, and text you when the car is ready.
How fast does it ship?
Same-day across greater Los Angeles when ordered by 2pm. Next-day everywhere else from the LA warehouse. Ground is free.
Can I return a part that does not fit?
Yes. If the fitment call was ours, the return label is prepaid and we cover the freight. Thirty days on uninstalled parts.
Do you sell to shops?
Yes — without a separate portal. Four or more converters on one order price at trade automatically. Reseller IDs drop sales tax at checkout.
