This flat back coating also acts as an Anti-Corrosion layer that will enhance the durability of your exhaust while also trapping heat and noise within the piping to increase performance and reduce interior resonance.
The tone of these exhausts is much more mellow while still retaining a mellow yet aggressive tone at Wide-Open throttle.
