Our choice for an overpipe on the BRZ/FR-S/GT86. These offer substantial clearance to the subframe, thus reducing the chances of contacting the body and annoying rattles (though it is dependent on the header design as well.) 2.5" and entirely stainless, it will likely outlast the vehicle. Please note that these are extended backorder. You can place an order but there is no definite ETA. Any orders cancelled are subject to a 5-20% restocking/cancellation fee depending on status.
