This is a high flow, high performance 3 inch (76MM) pair of downpipes with heat shields to fit 3.5 inch exhausts- the product mates up to the Y piece exhaust section of the GTR exhaust and will mate up to both our aftermarket parts and other aftermarket 3.5 inch exhaust systems. Incredibly durable and hand-welded from 100% 304 grade stainless steel, this part is among the best performing and most durable on the market and is available for a great price. All gaskets and bolts are included (as pictured).
Please note that the standard Nissan GTR Exhaust is not 3 Inch or 3.5 Inch so this is strictly an aftermarket part, not guaranteed to fit OEM. In our off-the-shelf Topgear Nissan GTR systems, this downpipe can be switched interchangably with our standard downpipes.
