We have temporarily closed our books to new orders for manifolds/hot parts, downpipes, and O2 housings while we put our entire focus on fulfilling current orders.

Smaller items (oil drain kits, shift lever/bracket, alternator adapters, etc.) are still in stock and often shipped the next business day.

We don’t have a “buy it now” feature because we feel strongly about getting you the manifold that fits your setup and your goals. By filling out this client worksheet, you can help us begin that dialogue. After receiving the completed sheet, we will review it and contact you within 1-2 business days.
