Show original supplier description
The 2JRacing B15 QR Stainless Flex Resonated Midpipe is a 2.5" exhaust system designed for the QR B15 chassis, specifically the 02-06 Nissan Sentra SER Spec-V. Constructed from 304 stainless steel, this midpipe features mandrel-bent tubing to ensure maximum flow and performance. It is designed to fit with both OEM and aftermarket exhausts, as well as 2JR and other aftermarket 4-1 headers. The package includes the rear gasket, bolts, and nuts for installation. An optional OEM donut gasket is available, or you can reuse your existing one. For those seeking further customization, options are available to substitute the resonator for a high-flow cat or to include both a resonator and a high-flow cat, though these modifications may add to production time. The resonator itself features a stainless perforated core for extended durability. This system is hand-welded by 2JR and utilizes top-tier exhaust components for a complete stainless steel solution.
