IMO, these almost does nothing unless you upgrade your ignition system.

sa muffler issue, ayoko ng nakalabas ang malaki at makintab na tambutcho, mas ok ang design pag scub, pero mawawalan daw ng torque pag walang muffler?? any other way na maitago ang muffler? pwede kaya iklian ang piping at nasa loob pa konti ang muffler?
scab? use only that if you are into drag racing... you will lose torque from the low-mid rpm range (which you'll need since you are driving a matic). also, the noise & vibration will drive you nuts after a few days... :bwahaha:
