HKS 31021-KN001 Legamax Exhaust for 2009+ GT-R, Burnt Tips, Flux Welded
HKS Legamax Premium Cat-Back 31021-KN001 Exhaust for 2009+ Nissan GT-R. This is the flux welded version (TIG welded version listed separately). Features a full 3″ mandrel bent, stainless steel design with dual titanium-style 119mm tips. Direct bolt-on system. Runs at only 1db louder than stock exhaust (for a louder version, see the race exhaust, which is listed separately).
Flux vs. TIG welded version: TIG welding provides a strong bond than Flux welding. Primarily, the choice between the two is a matter of cosmetic preference. Flux welds tend to show a rougher bead appearance, whereas TIG welds produce smooth un-beaded weld look.
The GT-R Legamax Exhaust systems include just the rear half of the exhaust system, or the cat-back half. It does not include the center section to complete the exhaust; we have the non-silenced and silenced center pipes listed separately. Please double check stock before adding a center pipe to your order.
