Calling all gearheads and DIY warriors! This 4-inch diameter, 48-inch long straight pipe is your ticket to custom exhaust glory. Made from premium T304 stainless steel that laughs at rust and corrosion. The mandrel bending keeps airflow smooth (unlike those crimped bargain pipes), and the humped ends make clamp installation a breeze. Perfect for intercooler piping, turbo setups, or when you just need to replace that rusted-out section. Warning: Professional installation recommended unless you're really good with a welder. Ships as one straight pipe - cut to fit your specific ride. Pro tip: Pair with our 45° or 90° bends for a complete custom system. Your neighbors might hate you, but your car will love you.
