BJG Custom 4.5in Race Downpipe: Toyota GR Supra B58 - Stainless Steel

Give the turbocharged straight-six a more purposeful voice with the BJG Custom 4.5-inch Stainless Steel Race Downpipe for the Toyota GR Supra B58. Positioned immediately downstream of the turbocharger, its free-flowing race configuration reduces restriction at the start of the exhaust path, bringing a more pronounced turbo soundtrack and a sharper exhaust note to a properly calibrated build.

Brushed stainless steel, visible precision weldwork and the engraved BJG emblem create a clean, understated finish. A braided flex section accommodates movement through the exhaust assembly, while the tapered lower section and formed outlet follow the routing shown in the product photos.

Highlights

• 4.5-inch stainless steel race downpipe for the GR Supra B58 application.
• Brushed metal finish with engraved BJG branding.
• Integrated braided flex section, turbo-side flange and mounting bracket as pictured.
