as you can see in my sig, i have a 2.5" downpipe and a 2.5" straightpipe. now seeing these mods, how much power do you think that my stock catback system is robbing me of?

 

I doubt its robbing you of much.

You've already removed your 2 most restrictive items, pre-cat and main cat, so having a slightly better flowing y-pipe and mufflers isn't going to make too much difference...

Just work on you launch to beat that Supra, lol...

 

maybe i'll actually try a launch next time and see what happens... :/
i'm just trying to figure out what else is proventing my boost from being around 10 psi. everything i have should make it around atleast 9 or 10... the only 2 things i have left are TID and catback...

 

damn, i'm worthless.

 

Well if its only a couple of psi that you're after, then yeah, a new cat-back and TID can probably get you that.

 

what if i were to get a boost controller? (providing that i had enough fuel,) do those just force your turbo to produce more boost than it would normally? then i could get it to like 11 or so.

 

Yes, a boost controller will allow you to raise you boost by quite a bit.

It doesn't force the turbo do produce more boost. What it does it prevent the wastegate from opening, until your desired level of boost has been reached.

 

ahh, yeah thats what i thought. i love you canadians. i met a canadian girl last night and she was kinda hot.. she said 'eh' as well.

 

we say, 'eh'?

 

is that a bad stereotype or something? cause all the canadians that i have talked to have had a bad northerner/eh accent.

 

NO, its true, lol...

 

Yes it is. Just spell "Canada" and it proves my point.

 

hahaha

 

nice

 

expect 1-2 psi from the catback. The stock one blows. I'm using it to keep boost down, but it'll be pitched with the new motor.
