Hey everyone, I was looking to get a header and downpipe combo in the future. I have decided to go with the zzp mid-length with catted down pipe. My question is, will I need a tune after installing them?

you wont need a tune, but you would see better gains by having it tuned.

the stock exhaust manifold is good to 350hp you wont see much of a change with a header

it may flow enough for that, but a midlength header will change the car in other ways. when i installed mine way back i noticed more mid range torque, both at heavy throttle and around town type driving. i also remember my average fuel mileage went up just over 1mpg.

Same here. Same hill everyday to work had to downshift if going slow. Now cruises right up in 5th no problem.
