A90/A91 GR Supra Downpipes – B58 Performance Upgrades

Shop GR Supra downpipes in Australia at Sequential Racing. A downpipe replaces the restrictive factory unit after the turbo on the B58, improving exhaust flow and turbo response and unlocking more power with a tune.

Choose catted downpipes from Active Autowerke, AMS Performance, VRSF, Armytrix and HKS, or catless options including our own 4.5" Sequential Racing downpipe. We can fit and tune at our Melbourne workshop – see downpipe installation.

GR Supra Downpipe Buying Guide

Catted or catless?

Catted downpipes, like the Active Autowerke GESI catted or AMS Performance street downpipe, keep a high-flow catalytic converter. Catless downpipes are sold for off-road and competition use only in Australia.

Do I need a tune with a downpipe?

Yes. A downpipe needs a tune for the B58 to run correctly and make the most of the extra flow. See our ECU unlock and tuning services.

What's the difference between 200-cell and other cats?

A 200-cell cat, such as the VRSF or Armytrix sport cat, flows more freely than the factory converter while still cleaning up the exhaust.
