So I am looking at getting a downpipe for my 07 Subi, but I have not quite decided on what to get. I definately am getting the bellmouth shape, but I have not decided between the bellmouth and the split/divorced style. Right now I have the stock turbo, and I'll have it stock for a while till i eventually get the money for the upgrade, so should I stick to a divorced, or should I stay bellmouth? And when it comes to dps, If i have no cat and a catdelete, will i lose my low end torque or will i still have a pretty good amount?
just some questions that i would like to get some feedback on
thanks guys--

 

They say that with a catless dp, you lose low-end torque but make higher-end hp. As far as the bellmouth or divorced, I read somewhere that the divorced allows the wastegate to vent to its own little area and the air is then later reintroduced to the dp, so it evens out the exhaust pulses but I have a catless TiTek (bellmouth) and it feels fine. Just so you know, boost creep is an issue you will have to deal with. Search around, there is some good stuff on the different styles of dp. Good luck.

 

when it come to boost creep, does that come from different types of the down pipes? or what would be the best dp for someone like me who is not looking for any track racing, but a daily driving and some daily messin around fast driving. ?

 

i am looking at the same titek downpipe from hopupracing.com ..

boost creep would be eliminated with a tune, such as the accessport 2.0

do you have the accesport importfantic? for reference

 

boost creep and boost spike can be in issue if you were to throw a divorced or sepereated (non wide open or bellmouth) downpipe

 

ofcourse once again you would want to reflash and tune the car with engine management upgrades
