It uses 4.5\" stainless steel piping, tapers to 3.5\" where a stainless flex joint is incorporated, then steps down to 80mm to meet the OEM exhaust; the diameter never drops below the stock 80mm. This version includes a 4.5\" GESI G-Sport ultra high output catalytic converter, which Active Autowerke states will not set a check engine light. The turbo flange gasket is included and comes pre-installed in the downpipe flange.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e4.5\" diameter piping, tapering to 3.5\" at the flex joint and 80mm at the OEM connection\u003c\/li\u003e\n\u003cli\u003eCasted upper stainless steel V-band for precise fitment\u003c\/li\u003e\n\u003cli\u003e4.5\" GESI G-Sport UHO catalytic converter, 400 cells per square inch, full 304 stainless steel construction including the substrate\u003c\/li\u003e\n\u003cli\u003eCatalyst rated for 500 to 850 hp applications; withstands up to 1500°F; reaches operating efficiency within 9 seconds of startup\u003c\/li\u003e\n\u003cli\u003eEPA registered and OBD2 compliant (1996 and newer vehicles); not legal in California\u003c\/li\u003e\n\u003cli\u003eTIG-welded 304 stainless steel, 1.5mm wall thickness\u003c\/li\u003e\n\u003cli\u003eBolt-on, no cutting or welding required\u003c\/li\u003e\n\u003cli\u003eMade in Miami, Florida\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1x catted downpipe with GESI catalytic converter\u003c\/li\u003e\n\u003cli\u003eTurbo flange gasket (pre-installed in the downpipe flange)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eNo performance tune is required to run this downpipe (per Active Autowerke).
