I had issues with my o2 sensor down steam and upstream haha. Took off the stock headers like 3 times just to get to the o2 sensor. Ordering a set of 2inch here soon hopefully it should be quick install for me😂😂
Now I'm glad i got a base model over a grand sport 😂. Just ordered these headers and xpipe. Bought a friend's modded z06 npp mufflers also.Going to start on my TSP stage 1 cam install today.
