Direct replacement for the restrictive factory downpipe, with TIG-welded construction, machined flanges, and all gaskets and hardware needed for install. The downpipe is the single biggest exhaust flow restriction on a stock or mildly upgraded SR20DET. opening it up is one of the most felt bolt-on changes you can make.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Does\u003c\/h3\u003e\n\u003cp\u003eThe factory SR20DET downpipe is narrow, restrictive, and a known choke point even on stock turbos. Stepping up to a 3-inch downpipe drops backpressure at the turbine outlet, helps the turbo spool more efficiently, and lets the rest of the exhaust system actually do its job. Pairs well with a 3-inch O2 housing (or skip the O2 housing entirely on race-only builds) and a 3-inch catback.\u003c\/p\u003e\n\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1989-1994 Nissan 240SX (S13) with SR20DET swap\u003c\/li\u003e\n\u003cli\u003e1995-1998 Nissan 240SX (S14) with SR20DET (factory or swapped)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eInstallation Note\u003c\/h3\u003e\n\u003cp\u003eMost installs are direct bolt-on, but depending on your specific exhaust setup, headers, or turbo, minor customization (clearancing or alignment work) may be needed in some cases.
