STi Modification Path

Really...never heard anyone have a negative opinion with them. Gimme a run down of what you think if you don't mind...reviews are always a plus for us

sure, they are noise, i think it is because it doesn't have that extra ruber cover that i have seen in other springs.
if you see this picture you can see the extra ruber that i am talking about. i also think that is more of a bling-bling oriented spring set.



if i could doit again i would go with prodrive or STI pinks. i am thinking on selling them and get the prodrive ones.

have some one heard something about the STI Tarmac springs ??? any opinions ???

[stight]

I am not so sure what the big problem is with COBB Springs. The only rubber in the set up is the in the hat section. Without that you will experience all kinds of road noise. Here is another photo showing my set up. I am very satisfied with the performance of COBB springs and bars.

So I have a Downpipe question for you guys:

Should I go catted or non catted?

Here is my situation. I live out in the country where I dont need to get my STi smogged, I have veteran plates on it that are good for life, and I dont drive my car like a tard so Cop trouble isnt realy an issue. Is the HP gain from a straight DP decent? Thanks guys =D

The HP is virtually identical in a high flow catted DP vs a non-catted DP. Have you considered the potential for fuel cut you may get with a non-catted DP? That is the one real reason I always recommend a DP with a high flow cat. That little bit of back pressure goes a long way to ensuring no fuel cut. Now..if you are running the stock catback exhaust, then you can go with the straight DP as your resonator pipe and mufflers will give you enough back pressure. If not, I'd recommend the HF catted DP.

Ok looks like I will go with the HF catted DP,Thanks for the info and advise!

I've got a '03 STi (2.0L European model) with a ProDrive performance pack (I think it includes a remap, HF cat pipe, fuel pump and a nice silencer). Does it make my car stage 2?

BTW, I also have Tein Basic and can recommend them very much for all arround usage

Only thing that makes it Stage 2 will be a downpipe (or as part Turbo Back exhaust) AND engine management to "tune" the car to run safely with the downpipe. Sounds like your "High Flow Catpipe" might be the downpipe...that and an upgraded fuel pump would warrant a remap of the ECU. Sounds like you very well could be Stage 2.

Check the downpipe coming off the turbo and see if it looks stock or not. Plus, post pics of your STI! We don't get to see many 03 STIs around here since they aren't USDM!

Mikie, here is a thread of my car detailing. All pics are external. If you want some under-the-hood or internal pics, let me know 27 hours to detail my MY03 STi
In order to see the DP, I have to lift the car, right? I can not see it good enough from above?

ok, I just confirmed the the HF cated pipe IS a DP only (not the whole TBE).
Together with the prodrive remap, I am glad to know that I'm stage2!!! As an extra, I have an upgraded fuel pump and a nice sound from the axle back (also prodrive)

You should just be able to look to the left of the TMIC. But it is weird that they would have add and aftermarket DP and add an axleback. Why leave the midpipe stock? I bet it might be a full TBE in that case...

But yes, sounds like a legit stage 2 to me

definitely a great looking car...your detail job did wonders on the paint. You don't see many pictures that show off the gold flake that well...and I love the EDM/JDM STI wheels
