14851 exhaust size question!

Alright i know this has been beat up and trust me I have done my searches and have not found the answer! I have 2 14851's and am going to put them on next week, Should i do 3" cat back to 2'1/4 at the split or 21/2 cat back to 21/4 at the split.....Im thinking 3" but not sure that could be to big and kill the exhaust velocity...anyone know? Also my car is stock but will be stage 1+ soon and will eventually have BT...or maybe even......BAT! haha Thanks guys~!

Glad to hear ya got them

Depending on how long it takes for you to go BT/BAT I would get 2.5" to 2.25" after the Y.

Otherwise it will sound like ass.

save the 3 inch for later on... odds are if you go BAT you'll change your whole exhaust anyways.

Damn you work fast, lol....those things sat for 1 year

I have decided to just buy a whole exhaust system now....all the shops near me wanted some insane amounts of money to make the exhaust, plus they would do crush bends and use odd diameter sizes

^that sucks man... custom FMIC piping/MAP sensor and BOV fitting + full 3" mandrel bent turbo back (not including cost of the muffler) was only 800 for me.... and my FMIC core + my muffler was less than 200

if you were closer i'd say it'd even be worth a drive up here to have my guy do the work. he's amazing.
