3" dp and boost creep

[Shi]

Right now I have a 3" cat back and a injen intake. I want to get a 3" dp and a 3" high flow cat. I was wondeing if that will cause boost creep? I have a t25 on stock boost seting (no boost controler or boost gauge yet) I am trying to wait to get the gauge till after the exaust is done. Thanks all

Get the guage first, it's not that expensive (compared to the exhaust system) and it is more important IMO.

It won;t boost creep with the t-25 i don't think...

When I added my 3inch DP and HIFLO cat I got no boost creep. Gained some power at top end. Glad I went 3inch.

actually it would prolly creep like a #@%#@%#@%#@%#@%.. 3" all the way back and the stock o2 housing is begging for boost creep.. port your o2 housing and youd be fine though

Just a question but wouldn't a free flowing exhaust just help it not to creep. If anything I would think the o2 housing would cause the creep because after the o2 it would flow better. It doesn't creep with the stock exhaust and o2 so why would the o2 cause creep now with everything behind it flowing better. There is probably something I don't know so this is a question can someone enlighten me please.

naw, it won't creep, only in cold-er weather it will like 2 psi at most. Mine didn't but mine was/is a 14b with 3" turboback and unported a o2 housing.

 

[larryd]

uhm, im speaking from personal experience here guys.. T25 with Apexi N1 downpipe and catback and testpipe.. with a stock o2 housing it creeped BAD.. like 5-6psi and then dropped off with the ported o2 it never creeped

3" Exhaust is quite likely to cause boost creep, actually, no matter what turbo you're using. Ported wastegate along with a bigger flapper AND ported O2 housing are the only real way to stop it without going to external wastegate.

Listen to LarryD.

 

[larryd]

yea, i got a wiseman backing me now

Thank's for all the help guy's. Does anyone know where I can get my 02 ported at? I live in the Philadelphia area. Also would a evo 3 02 be better than porting? Thanks again

Get the evo that's what I got and there is no creep at all. I also ported mine and it's great. Does anyone know why bigger exhaust causes creep just wondering cuz I like know as much as i can. Heh it's really true you do learn something new everyday , like last night I finally got to race te GSR that's been talking sh!t for 3 months now I learned that's all he does is talk cuz he didn't back it up. I'd love to see him race a stock RSX type S Because I'd want to see his face at the end when he lost to another n\a car. That was his excuse when i won but before we raced he said he's beaten turbo DSMs before and there not really that fast. Off the line I smoked the tires(oops) giving him a car link and a half jump in 1st but when I hit 2nd that lead disappeared almost before i realized it. Point being I don't have anything against Hondas I actually like them but don't talk sh!t it just makes you look like an a$$ if you lose.
