Nah, I saved mine. I think what I'm going to do is put the stock one back on, but only enough to where it looks good. I'm not going to spend the time putting back on just the way it was. I think even if done half-assed it'll still pass the sniff test. Visual for sure.
Can't wait though, because the moment I am done with Smog, I'm going to order my header/exhaust/flexpipe/tune.
