Alright I was wondering if anyone had a ZZP setup, the mid/long (I cant remember what they sell) Header, Downpipe, and Cat all 3" and what they think about it?

I was going to go with the HAHN set up but for the price I could save and piece togather a stage 2 kit.

Also, the Stage 2 kit, if I order a PCM from say ZZP, do I still have to get a tune or i that it, and how difficult is it to install that?

Thanks guys for any information
