Description

The PLM Power Driven B-Series Swap TA AWD header is engineered for B-Series engine swaps into AWD vehicles, specifically EG Civic, EK Civic, and DC2 Integra models. This one-piece header is designed to enhance exhaust flow through its true 4-2-1 Tri-Y merge collector, aiming to deliver significant low to mid-range and peak horsepower gains. Constructed from robust 18-gauge, 304 stainless steel, the header features a .38" thick flange that is CNC machined for a precise fit. The welds are 100% TIG welded, ensuring both strength and aesthetic appeal. The collector is a true 2.5" OD Tri-Y design, further contributing to efficient exhaust scavenging. Installation note: An extension pipe is required for proper fitment. The header includes both gaskets and necessary hardware. PLM backs this header with a 1-year warranty and offers a 30-day return policy.
