The Speed Logic race catless downpipe removes the restriction built into the OEM downpipe so the turbo spools faster and makes more power, and it gives the car a deeper, louder exhaust note along with the turbo sounds the factory system muffles. Depending on tuning, supporting modifications and fuelling, the gain runs from roughly 20 to 25 horsepower. Every Speed Logic downpipe is built from 304 stainless, 100% TIG welded with all welds backpurged in argon, and carries a lifetime warranty.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e4\" stainless steel race catless downpipe\u003c\/li\u003e\n\u003cli\u003eFull 304 grade stainless steel construction\u003c\/li\u003e\n\u003cli\u003eAdds 20-25+ horsepower and 25-30+ lb-ft of torque with adequate tuning\u003c\/li\u003e\n\u003cli\u003eRemoves the restriction built into the factory exhaust system\u003c\/li\u003e\n\u003cli\u003eDelivers turbo sounds and a deeper exhaust note\u003c\/li\u003e\n\u003cli\u003e100% TIG welded\u003c\/li\u003e\n\u003cli\u003eAll welds fully backpurged with 100% argon\u003c\/li\u003e\n\u003cli\u003eWelds are not ground or polished\u003c\/li\u003e\n\u003cli\u003eCatless - off-road use only, not available for sale in California or other emissions-testing states\u003c\/li\u003e\n\u003cli\u003eIncludes a Speed Logic LIFETIME warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\u003cli\u003eComplete downpipe as supplied by Speed Logic.
