98-02 Honda Accord 4-1 Style Header Stainless Steel
Stainless steel 4-1 merge header built for the fourth-gen Accord engine bay. Engineered to improve exhaust scavenging and flow characteristics over the factory manifold. Constructed from mandrel-bent stainless tubing for durability and corrosion resistance.
Do I need new gaskets and bolts to install this?
Yes. The factory gasket set will not seal properly on a new header. Source a quality manifold gasket kit and stainless steel header bolts rated for exhaust heat — do not reuse factory hardware.
Does this header come with a downpipe flange or O2 sensor provisions?
The header includes a 4-1 collector outlet. Verify your downpipe interface matches before purchase — adaptation may be required depending on your exhaust system configuration.
Will this require engine bay modification to fit?
Test-fit required. Headers are tight in the Accord bay. Some steering or suspension components may need clearance verification; minor adjustments are common on tight installations.
