Kook's has produced a top of the line set of headers for the 6.1 & factory 392 SRT-8 line of Hemi's. This system is our choice for SRT-8 customers who are getting header and high flow cat upgrades performed here at HHP. Kooks headers have repeatedly shown the highest gains on stock and modified 6.1L motors during dyno testing by HHP.
Ceramic Coating Available
Ceramic coating your headers will allow you to keep your engine compartment temperatures lower, increasing horsepower and extending the life of the components around the headers. Customers selecting ceramic coated headers, please allow up to an additional 7 to 10 days for shipping. We are constantly receiving in headers from our coater and they're going out the door as quickly as they come in.
Other Suggested &/Or Required Parts
HHP strongly suggests that you pick up a set of OEM SRT-8 exhaust gaskets (05038098AA / 99AA) for use when you install these headers. In addition, custom tuning is highly recommended for your SRT-8 when you add long tube headers in order to adjust fuel settings to keep your engine running safe as well as to keep you from getting a Check Engine Light from swapping out your stock catalytic converters. HHP has the best email tunes on the market for these headers. Give us a call to discuss what we can do for you.
