Finally did my exhaust
Exhaust :
Secondary Cat Delete : Custom Pipe extended Midpipe
Midpipe: FlowMaster 81083
Muffler : FlowMaster 8430152
Valve : Stock NPP ( cut and welded )
*EDIT* TIP ( decided to swap the stock tips ) : Flo-Pro Universal 2.5" ID / 4.5" OD / 7" Length
Issues : Stock valves rattle. It was doing that with stock NPP. I need to epoxy the pin.
Comments : I like it . Don't love it to say. It's really really deep . If you do not have the secondary cat delete there's no drone at all. I have slight drone in tour mode at 1400-1600 rpm .. at 70mph it's fine .. from 60-65 mph there's a slight drone. If you put it in sport mode .. it's really loud! I mean really loud. Vibrates the ear drums lol.. same amount of drone at cruising speeds because the valves close at cruising speeds. Safe to assume it will drone with valves being open at cruising speeds ..
Fix : adding a Jpipe to get rid of the drone. Should improve it. I have seen another member make that comment and it fixed the drone according to him. we shall find out after i install the JPipe
Cost:
MidPipe $300
Mufflers $160
Tips $90
Install $250
Total : $800
So overall I can say not bad to spend $800 total with install for full Catback Exhaust while keeping the NPP function
