BORLA(r) has developed an exhaust system for the Hyundai Sonata N Line. Our Cat-Back(tm) system has been tuned for flow and sound specifically for the 2.5L 4 cylinder engine in the Sonata N Line. The S-Type sound level delivers a more aggressive and sporty sound without any drone in the cabin. This system features quad 3.5" black chrome on T-304 stainless steel tips, but is also available in a chrome finish. Using BORLA(r) Stainless Steel Polish p# 21461 is NOT recommended with these black chrome tips. We suggest cleaning the tips with hot water and a microfiber cloth. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit.Each Borla(r) Exhaust System is built from premium T-304 series stainless steel to give you the absolute best in performance and durability.
