and I'm not ozone friendly anymore.. :P Well, yesterday I went and tackled a lil project for my STi, that is to install my 3" catless downpipe(mated to a stealth back STi exhaust)! The install went pretty smooth and the only thing that is a PITA are the hosings from the Top mount intercooler from the back and the freakin charged pipe from the turbo.. I bust a few knuckles taking that shit in and out, but other than that it went butter smooth.

All in all, I was amazed how this thing woke up my VF39 turbo! I'm spiking 15.5-16 psi and it falls and hold at 13.5 psi.. Oh yeah, and no boost creep at all. I drove it a few miles around the block and to my butt dyno it pulls like a biatch! If you guys thought a stock STi is quick, mine pulls 1-2X harder than a stock form. The exhaust rumbles a lil bit more, with ocassional back firing, and the sweet sound of turbo spooling and whistling while you let off the throttle. Ok, here are some pics of the mayhem from yesterday..

Me smoking the pipes..:P


TMIC are off..


Stock dp are off..

Now, that is a healthy turbo.

Bling

 

3" Dp installed.

more bling


That's all folks! It's time for me to a hunt a few V8's...

 

Do you notice any big difference?????

 

Yes! The turbo spool a lil earlier, the low end grunt improve a lil bit, but the biggest improvement are the mid and high end pull.. It hits hard it's not even funny..

 

wow must be amazing to drive it, looks great.

 

Boost kicks in it's like you're in a diff world. I just have to watch out for :cop: everytime I'm on boost..

 

I likey!!!!

 

now all you need is an boost controller and jack that bitch to 18 psi :wackit:

 

I beat you by a punch Phil! I just ordered it couple days ago and it should be here next week.. I got the TurboXS Highperformance MBC..

Now, what I need is a UTEC ecu re-flash..

Have you tried some 4th gear runs? I have read that a catback gives you boost creep and that porting the wastegate is the only solution to prevent it.

 

It's basically a turboback set up that are notorious for giving us STi onwers some crazy boost creep.. Yes, you can port the wastegate and prevent it.. I don't have any boost creep at 4th gear at all, it hold steadily..

I'm spiking 16 psi and hold it at 13.5 all the way.. No sign of boost creep..


Some people with turbo back and MBC are like this: 18 psi spike hold at 15 psi then it will spike at 19-20 psi..That is some crazy boost creep..

 

Nice! You notice any smells from your exhaust from running catless. Every other person i talk to says it smells like sulfer all the time on theirs, but mine never smells bad at all.

Yea I read about it a while back. I have always liked a silver or black STi with silver BBS rims. What else is out for the STi? Is the Exede or UTEC finally out?

 

That's the only downside of it. Mine doesn't smell that bad, but you can tell that my car is running catless..

 

They pushed the released date again. It suppose to come out at December/January, now it's March/April.. This is the mod that will change an STi forever.. Move over EVO's it's our damn turn to turn the table..:P

 

my brothers wrx has an invidia turbo back, and it starts to smell pretty bad after riding in it for a while. it pulls like a mofo though. sti hunter are you staying w/the tmic? if you ever sell it let me know.

 

Cool....I really like the STi. I would swap trunks out and get rid of that wing of I bought one. Also, I am not a huge fan of the blue carpet, but that can be swapped too.

 

do they have 3 cats on the sti like the wrx?

 

Only 2 cats.

 

Hehe, if i swap for a bigger turbo I might as well go for the FMIC set up, but for now it's all good. I'll let you know first hand though.

 

LOL, you know i took the wing for a day and leaving my trunk with 12 small holes. I like it alot, but if you look at the car sideways with the huge ass hood scoop without the wing, it doesn't look proportion..

 

looking good man

 

Nice work. Did you get any times pre-cat removal?

 

When can i drive it?

 

when u learn how 2 properly drive a car and not use a tree as a 3rd lane
