Chrome Warning:
Due to a revised chroming process brought on by recent EPA regulations and high labor costs, today\'s chrome is not the quality of days gone by. Be Aware: Exhaust components which are chrome plated are now much more susceptible to blueing, blistering, peeling & corrosion. We see very few headers that do not change color once exhaust temperatures are achieved. No warranty or returns on chrome exhaust items once they have been installed.
Header Return Policy:
Please refer to the header measurement chart below to make sure the header will fit your vehicle and application before ordering. In the event you order a header that will not fit your vehicle and application, you may return them for a refund, providing you don\'t damage the header. When you receive the header the finish will be protected and must remain unscratched for a refund. If you bend or dimple any of the tubes or scratch the finish, we will not be able to sell the header and will not be able to process a refund. Use care when trial fitting headers. Repack them well to prevent damage returning them to us. We won\'t process refunds for scratched, dimpled, dented, or bent headers.
We also have these same headers available in:
- Painted Flat Black
- Polished Stainless Steel
- Ceramic Hot Coated
We also have thousands of other High Performance Parts in our store.
