Thats what I thought because the one in there is already high flow and has a nice throaty sound already but not too crazy because the stock resonator and mufflers are still present.

The year is an 2001 3.8 N/A. My last ditch effort to do away with this stupid P0420 is to send in my PCM to ZZperformance to get it flashed without the P0420 but don't like having the car down that long.
