Just wanted to share with anyone on the fence about headers: DO IT!! I had OBX long tube headers with cats installed yesterday (super easy with a lift) and it's amazing! I already had Flowmaster American thunder exhaust but these headers take it to the next level. The car has so much pull right out of the gate, previously it didn't really wake up until 3K RPM, now it's in serious beast mode. Just waiting on my tune tomorrow morning
I know there's a lot of debate about the OBX headers, but I went with them because of the good reviews and the affordability. The guys at my shop loved them and were very impressed. They sound amazing.
