FAQ

Do I need a tune with a B58 downpipe?

Yes. A downpipe changes exhaust flow, so pair it with a tune such as the Bootmod3 B58 map to avoid codes and get the full gain.

Does a B58 intake fit both F- and G-chassis cars?

Not always. Engine generation and chassis matter, so check the fitment list on each product or text us your VIN.

Do these parts fit the Toyota GR Supra?

Many do. The Supra uses the B58. Look for "Supra A90/A91" in the product title.
