Post cobbtuning intake with headers and cat-back.

I just installed my cobbintake and I have a borla header and a borla cat-back. Now I just ran it and it feels like I lost more bottom end tq. But I did not reset the ECU. So would I have to reset it or should I take off one of my cats? Thanks

reset the ECU before doing anything dramatic. But yeah, see if you can replace the cat with a higher flowing one.

Increasing the size of your exhaust seems kinda pointless to me, if you leave some smaller items on there, like the cat...cause then there's still some restriction...
