Show original supplier description
The Spyder Auto 4-2-1 exhaust header offers a high-performance upgrade for the 2003-2006 Honda Accord 4 Cylinder models. Constructed from premium T304 stainless steel, this header utilizes mandrel-bent tubing and features CNC-machined flanges with durable TIG and MIG welding. The 4-2-1 collector design is specifically crafted to even out exhaust pulses, leading to power improvements of an estimated 8-12 HP. It is designed to enhance power delivery from 4000 RPM to redline, without sacrificing low-end torque. The header includes an O2 sensor insert for seamless integration. Professional installation is recommended for this exhaust header. This part is compatible with the 2003, 2004, 2005, and 2006 Honda Accord 4-cylinder models, specifically the 2.4L engine. The fitment details also indicate compatibility with Accord Wagon models for these years.
