which of these gets priority and also I know I need to either reflash the ECU or get an AP.. so far the car has a full cat-back exhaust, HKS Carbon.. just need direction on which to go with and if the UP/DP are a good next mod.. thnx

 

From a practical point, installing the UP requires the removal of the DP. So you probably want to do the UP first. If you can get both done, even beter. You don't want to just do the DP then have to remove it again later to do the UP. Also, make sure you pick up new gaskets especially for the UP side of things, they're cheap insurance from boost leaks.

 

and make sure you don't buy it used from a mexican.

andddddddddd don't do an install past 3pm on sundays, cuz napa will be closed and if you are missing any bolts, you won't get it.

 

Do the UP and DP at the same time...that's the best way.

Yes, do it in the morning so you can buy hardware or anything if it breaks.

 

up/down pipe = same time

you can actually run these mods without a reflash...i did for a while before my AP. just put in a cell fix or you could just live with the cell turning on and off everytime you "after fire" (backfire). just make sure you reset your ecu...IMO these are the best first mods you can do (powerwise) because, any other future mods would recomend you having these pipes on the car already IE: bigger turbo...

go with a HELIX UP\DP! its the best mod i did so far. sounds great too. if you want someone to install it for you then let me know i will do it for you. i have done a few.
