Hey im pretty new the the forums but i read this thing like its the bible. I have some questions for people out there. I know someone on here will def know the answer. Ok frist question anyone know if HKS makes a exhaust for the TL. Youtube shows them with exhaust test vids but were they just "custom" exhausts with hks mufflers, or do they actually make a full set. Last question is side marker related. Ok some times one of them is dimmer then the other then it brightens up is it dieing? Do i need to replace. Thanks a million guys and gals I LOVE MY TL SO VERY MUCH!
