boost increase with new exhaust?

[cgmtboarder]

ok so when i put my full exhaust on my car will my boost go up? cause if so i need to get a boost controller

No your boost wont go up. but your turbo will spool faster and if your wastegate cant handle the fast spooling it will creep. SO i would suggest getting a boost controler.

ya im going to. just making sure. wanna be prepared for whatever i may run into

It may go up a little. The main issue becomes boost creep, usually only a very common thing on the Evo 3 16G's though.

+1. You could also go with an external dump wastegate or o2 housing.

well im using the stock turbo cause its all i need at the moment. but i figured while i was getting the catback and the down pipe i should prob get a bigger o2 housing also. should sound awsome!

Well if you're running the stock 14b, a 2g o2 housing can be had for cheap and would greatly improve with exhaust backpressures compared to your stock o2 that's on. While you're at it port the o2 for even smoother flow.

You'll creep with the stocker with an exhaust. It gets to be very annoying too. I eventually bought an E3 16g and it also crept. I got the wastegate hole ported way out. and bought an external dump for the internal gate. it still creeps in 3rd at 5k but it's all good. just gotta pull your foot back or get fuel mods. and run 18psi like it wants.
