I've have the entire system from the APR TIP, thru their DP, their resonator and the rest of the exhaust system out to the Brushed tips on for 2 years. It's clean, sounds great, no drone and just had a stage III IS38 tune with the more toned down pops and bangs, perfect. There is no sign of rust anywhere.
Sounds good! Would you happen to have a sound clip?
