Show original supplier description
Its polished silver finish offers a clean aesthetic under the vehicle. The piping features a 3-inch diameter that splits to 2.5 inches and is mandrel-bent for optimal exhaust flow. This kit is designed for a direct fit on all 2015-2021 Subaru WRX and WRX STi models, including a 3-piece mid-pipe tube, five gaskets, and a hardware bag. This resonated mid-pipe is intended to be installed with factory mufflers and bolts to the stock downpipe. However, it is important to note that this kit does not work with aftermarket exhaust systems or the SPT Mid Pipe. Customers have reported that the included bolts may be too large for the factory holes on the stock downpipe, and modifications such as grinding the factory bolt shafts or cutting the factory springs may be necessary for proper fitment. Despite potential installation challenges, users have experienced a deeper, more monstrous growl and improved throttle response, with the resonator helping to reduce overall loudness compared to muffler deletes.
