Ya more acceleration, and I got the free tunes for life

These cars respond more to deleting the cats that they do to the actual mid pipe itself.

OP, offroade mid pipe and tune will yield you the best results. If you want to add some used axle backs to change the stock exhaust, they will help a little bit more

If you have free tunes get a CAI and offroad xpipe that's all I got and you'll be under $700 mine makes 410 with that setup. After that you need to start looking at lighter wheels or a power adder.
