My first mod was AR DPs with JB4, which obviously was great in terms of power. Then I installed the PE exhaust. I found it to be too raspy with DPs, so I installed 2 resonators instead of the secondary cats. This got rid of the rasp but created more drone at lower revs.
Now I have my stock exhaust back on with the can flap open all the time.
Happy with this set up now.
