Custom Exhaust Header For Predator 301cc/420cc, Honda GX240/270/390 - Mild Steel Header Pipe For Mini Bikes & Go-Karts

Boost your mini bike or go-kart's power and sound with this custom-made exhaust header. It's designed to fit Predator 301cc and 420cc engines (like the Harbor Freight ones), as well as Honda GX240, GX270, and GX390 engines. Also works on Briggs 1450 305cc and Lifan LF190F-BQ 420cc. Made from uncoated mild steel, it comes sandblasted and ready for you to paint whatever color you like (header only, no coating included). It's about 30 ounces, with a 2-inch center-to-center measurement. Includes 2 bolts, 2 washers, and a gasket. Important notes: This is a straight pipe—it's LOUD and not street-legal. It gets hot (200-700°F), so be careful. Doesn't fit DuroMax XP16HPE/XP18HPE engines. Perfect for off-road projects where you want more performance and that aggressive exhaust note.
