MY05 WRX PPP to 300bhp?
Do you folks think decatting my downpipe (The one with the EGT Sensor...right?) and fitting some sort of aftermarket Airfilter would push my MY05 WRX PPP close to 300bhp and help reduce turbo lag?
If so could anyone recommend some specific parts (Pipes / Filters etc) that might help me, i'm pretty sure others will have tried the same mods
TIA...D-an-W

The WRX will tune to get comfortably into the 280s at certain rolling roads with a full exhaust system and suitable map. Might be lower at some of the less "optimistic" rollers, but the PPP doesn't tend to deliver the quoted power at less optimistic rollers either in my (fairly limited) experience. By doing the donwpipe, you will get more power and earlier spool-up.
You might just squeeze over 300bhp on the more optimistic rollers out of your existing turbo if you're lucky, port the headers, change to a lower pressure drop TMIC, change the induction and intercooler hoses etc etc (induction hoses helps earlier turbo spool as well). However, if you want to be well over 300bhp you need a bigger / better turbo. Bigger turbos will lag more.
The only 2 ways to get reliably over 300bhp without introducing more lag would be (a) convert to a twin scroll turbo - VERY expensive, or (b) fit a hybrid TD04 such as the Andy F ones.

15 would be about right as I have a decatted PPP exhaust with a prodrive sports downpipe and sti filter and this is pretty much the same as a full decat give or take a few hp and I'm hitting approx 280/280 after mapping.
