I'm not throwing a code. Just make sure you don't break your O2 sensors or jack up the wiring when you extend them. Ive ran it with the Motordyne Y pipe and Tanabe exhaust, both with the resonator attachment and the cat. The resnoator is slightly louder, but neither rasp once the pipes are warm, very minimal when cold.
