Installation Instructions
Dynatech highly recommends hiring a professional installer, one that is familiar
with the installation of off-road exhaust products. Headers are designed to increase the
performance of your vehicle, and as such are designed differently than your stock
exhaust system. Extra care must be taken to ensure that hoses, cables, electrical lines,
fuel lines, hydraulic lines, or any other objects are not in contact with, or located too
close to your installed system. (Nothing should be allowed to touch or be located too
close to the header/exhaust system.)
Dynatech competition exhaust products are not covered under any warranty
either expressed or implied.
Dynatech is not responsible for any exhaust product that has been improperly installed,
crashed, welded to, or modified in any way. Dynatech does not cover damage to any
related components. Neither the seller nor Dynatech will be responsible or liable for
any loss, damage, or injury resulting from the direct or indirect use of this product or
inability by the purchaser to determine proper use or application of this product.
Dynatech competition exhaust products are built for off-highway use only and are not
intended for use on street legal, pollution controlled vehicles.
The Dynatech Team takes pride in providing the utmost in quality and
performance. Should you have a concern about the product you receive, please contact
Dynatech Customer Service.
Congratulations on your purchase of the Dynatech / SuperMaXX exhaust
system for the 2008/09 Pontiac G8. We believe, and think you will agree that this
system is second to none in quality, performance, and ease of installation.
Please read and understand each of the steps involved with the removal of your
old system and the installation of your new header system prior to getting started.
While slight variations in either the header or the vehicle may cause minor
differences in the exact order of steps or the exact positions of components listed
in this document, the following narrative and pictorial information should guide
you during the removal and installation process to a completely satisfactory
install of your new header system.
Note: These products are intended for racing and off-road applications. Not legal for sale or use in the
State of California, nor in states which have adopted California emission standards.
