Trans-Dapt Exhaust Header 4870 Aluminum Build

Description

Product Overview

The Trans-Dapt Performance 4870 exhaust header is engineered for drivers who value both performance and reliability. Constructed from high‑grade aluminum, the header reduces overall weight while maintaining structural integrity under high‑temperature conditions. Its dimensions—7.25 x 4.5 x 2.5 inches—fit seamlessly into most mid‑size and full‑size vehicles, and the 1‑pound weight contributes to a modest reduction in front‑end mass. Designed to connect to standard 2‑inch manifolds, the header delivers smoother exhaust gas flow, which can translate to modest gains in horsepower and torque across a broad RPM range. The part carries the manufacturer part number 4870 and is backed by Trans‑Dapt’s reputation for precision engineering.

Usage

This header is ideal for street‑driven performance cars, weekend track cars, and enthusiasts looking to upgrade their factory exhaust system without extensive modifications. Install the header on any compatible vehicle equipped with a 2‑inch exhaust manifold to experience quicker exhaust evacuation and a more aggressive exhaust note. It performs well in daily commuting, spirited driving, and controlled track environments, offering a balance of durability and performance that meets the demands of both casual drivers and serious racers.

FAQ

Will this header fit my 2008 Subaru WRX?

The 4870 header is designed for standard 2‑inch manifolds, which are common on many WRX models. Verify your vehicle’s manifold size before purchase, but most 2008 WRX applications are compatible.

Do I need additional gaskets for installation?

While the header includes basic sealing surfaces, we recommend using high‑temperature exhaust gaskets to ensure a leak‑free connection, especially for high‑performance applications.

How does aluminum compare to steel for exhaust headers?

Aluminum offers a significant weight reduction and superior corrosion resistance, though it may have slightly lower heat tolerance than stainless steel. For most street and track uses, the aluminum design provides an excellent balance of performance and durability.

Is this header covered by a warranty?

Yes, Trans‑Dapt provides a limited warranty covering manufacturing defects for a period of one year from the date of purchase.

Can I weld this header for a custom fit?

The header’s aluminum construction can be welded by a qualified professional, but we recommend using the stock design to maintain flow characteristics and warranty coverage.
