T25 / T28 5-Bolt to 3" Downpipe Adapter A compact, fabrication-friendly solution for transitioning from a 5-bolt T25/T28-style turbine outlet to 3" exhaust tubing. Designed by GizFab and 3D printed from 316 stainless steel, the adapter provides a clean transition into a 3" downpipe while keeping the overall height to just 45mm. Ideal for custom turbo conversions, downpipe fabrication and manufacturers building their own turbo kits. Key Features 5-Bolt T25/T28-Style Turbo Outlet 3" Downpipe Outlet Compact 45mm Overall Height 3D Printed Construction 316 Stainless Steel CAD-Designed Transition Ideal for Custom Downpipe Fabrication Suitable for Professional & DIY Fabricators Trade & Bulk Orders Available Custom Branding Available 12-Month Warranty 5-Bolt T25/T28 to 3" Transition The adapter is designed around the common 5-bolt T25/T28-style turbine outlet arrangement, transitioning directly into a 3" outlet ready for fabrication of a high-flow downpipe. Rather than fabricating a transition from multiple individual pieces, the adapter provides the flange and transition as a single component. Simply incorporate the adapter into your downpipe fabrication and continue rearwards in 3" tubing. Compact 45mm Height Overall adapter height is just: 45mm Keeping the transition compact is particularly useful in tightly packaged engine bays where space around the turbocharger, firewall, radiator, driveshafts or surrounding components may be limited. 3D Printed 316 Stainless Steel Each adapter is manufactured using metal additive manufacturing from 316 stainless steel. 3D printing allows the flange and exhaust transition to be produced as one integrated component while giving considerably more freedom over the internal geometry than a conventionally fabricated adapter. The result is a compact component ready to be incorporated into a custom stainless steel downpipe. GMD Branding Standard retail adapters feature a discreet GMD logo. We appreciate that many of our customers are professional fabricators and businesses manufacturing products under their own brand. For this reason, the GMD logo has deliberately been positioned in an area where it can be easily ground away during fabrication if you would prefer the finished component to carry only your own branding. Trade Customers Building turbo kits or downpipes commercially? We offer bulk-order pricing and custom branding for trade customers. Bulk Discounts Bulk discounts are available from: MOQ: 5 Units Contact us with the quantity required for current trade pricing. FREE Custom Company Logo - MOQ 5 For orders of 5 units or more, we can replace the standard GMD branding with your own company logo at no additional charge. This makes the adapter ideal for: Exhaust Fabricators Turbo Kit Manufacturers Motorsport Workshops Performance Parts Retailers Private-Label Products Small-Batch Production Supply us with suitable logo artwork when ordering and we can incorporate your branding directly into the 3D printed component. Custom branding is subject to the supplied artwork being suitable for incorporation into the component and our manufacturing process. Fabrication Notes This is a fabrication component and should be installed by somebody experienced in stainless steel exhaust and turbocharger fabrication. Before final welding: Confirm Turbo Outlet Compatibility Trial Fit the Adapter Check Downpipe Routing Check Surrounding Component Clearance Allow for Engine & Drivetrain Movement Ensure the Exhaust System is Properly Supported Do not use the turbocharger or adapter to support excessive unsupported exhaust system weight. ⚠️ Check Your Turbo Before Ordering Although commonly referred to as a T25/T28 5-bolt outlet, turbocharger and turbine housing specifications can vary between manufacturers and aftermarket replacements. Customers should compare their turbine housing outlet arrangement with the adapter specification before ordering. The terms T25 and T28 alone should not be relied upon as a guarantee that every turbocharger marketed under those descriptions uses an identical turbine outlet. What's Included? 1x T25/T28 5-Bolt to 3" Downpipe Adapter Unless specifically stated otherwise, gaskets, studs, nuts, V-bands, exhaust tubing and other fabrication components are not included. 12-Month Warranty* This product is warranted to the original purchaser against defects in materials and workmanship for a period of 12 months from purchase. Our obligation under this warranty is limited to repair or replacement, at our discretion, where inspection confirms a manufacturing or material defect. The warranty does not cover incorrect turbo compatibility, incorrect installation, fabrication errors, excessive unsupported exhaust weight, physical impact, modification, overheating caused by surrounding system faults or damage occurring during welding, grinding or fabrication. Removal of the standard GMD logo for branding purposes does not by itself invalidate the warranty, provided the grinding operation does not compromise the structural integrity of the component. GizFab Motorsport Developments is an independent aftermarket manufacturer. References to T25 and T28 are used solely to identify the commonly associated turbocharger flange configuration and do not imply affiliation with, sponsorship by or endorsement from any turbocharger or vehicle manufacturer.
