These 8" Octagon Mitre stacks come with a "seamless overlay" Which also acts as a heat shield. You have no need to worry about anything in the back of your truck melting or burning if it ever makes contact with the exhaust. Not to mention, Does it get any cleaner then that? Add a bit of contrast to your build with a stack people cant miss.
All Stacks will come with a 5” inlet. In order to run a 4” Exhaust, a 4-5” adapter will be needed.
