Is there any real problems by putting a decat downpipe and Back Box on a brand new 04 STI with 1000miles on the clock, other than the warning light problem, or am I worried over nothing???

Just voiding the warranty possibly. Maybe the way to go is a PPP. Just a thought

Don't think PPP is worth the money????

From what i've heard it's like driving two different cars! Don't know how true this is someone on here should know. But from my point of view i think it is worth it because you keep the warranty.

Overboost, overboost, overboost, these are the worse symptoms of a downpipe on new age STIs. You can try different size restrictors though!

If you go for a decat downpipe then your going to really need a remap, then you have also invalidated your warranty, so whats worth more, 2k for the PPP or 1k+ for the decat d/p and remap yet no warranty when your engine may let go? (6k for a new one)
The PPP is the safest option and you have peice of mind (and you dont spash out 25k on a new car and invalidate the warranty straightaway).
I think Greasemonkey stated in another thread, if your going down this route then you should have got a JDM STi, would have been cheaper to start with.
