CTS Turbo 4.5" HIGH-FLOW CAT for MK5/A90/A91 2020+ Toyota Supra

Let your 2020+ Toyota Supra's B58 breathe with the CTS Turbo 4.5" high-flow cat. Built to drop in where the restrictive factory downpipe sits, it maximizes exhaust flow for the biggest power gains while retaining a high-flow 200-cell catalytic converter for a clean, streetable setup.

Why it works

• 4.5" high-flow cat downpipe, reducing to 3.15" (80mm) for a perfect fit to factory or aftermarket exhaust
• Replaces the restrictive factory downpipe with a high-flow 200-cell catalytic converter
• Precisely designed and tested on a real car in the real world
• T304 stainless steel, TIG welded and back-purged construction
• Incredible sporty exhaust sound, subtle when cruising, no drone with factory exhaust

Fitment (B58 engines only)

• 2020+ MK5 A90/A91 Toyota Supra with B58 3.0L engine only

We recommend replacing the downpipe gasket on install — factory BMW gasket 18328612538 is required (not included). Catalytic converters damaged by a crackle tune are not covered under warranty. Stage 2 software is required to avoid a check engine light. Only fits cars without GPF/OPF.
