Default read to see whats new on 2006 impreza

Ok seems only some ppl know the changes from the 2005 rs to the 2006 i, and it doesn't seem like they know everything. Here is the article straight out of Subie Sport incase anyone wants to read it it can help. "Formerly known as the 2.5RS, the newly dubbed '2.5i' remains the entry level offering in Subaru's sport compact lineup. It continues to share the same chassis as its turbocharged brethen, as well as a few of its suspension bits.
Though the new nose is one of the most evident change to this model revision, all the important changes are all kept under the hood. The 'stacked' manifold that first appeared in the 2004 Impreza has been changed yet again to improve airflow into the engine. Next, Subaru added its iActive Valve Lift system to make better use of the power across the spectrum. This changes the lift off the valves based on RPM and throttle input. The goal is to let in more air and fuel - thereby increasing power - without sacrificing low-end torque. Finally, exhaust gases are ejected courtesy of a new equal-length header design. These changes amount to a net boost of horsepower to 173 ponies, up from last year's 165.
If you own an RS or TS and are wondering how a set of Subaru's 2006 equal-length headers would sound on your car, forget it: The new headers are not 'bolt on' compatible with earlier 2.5RS models. This is because the new 2006 also has a modified oil pan that allows the piping to coil close to the underside. (hmm that sounds to me like you can swap the header and oilpan for a fit haha) Conversely, performance exhaust systems designed for the RS and TS will most likely not fit on the new 2006.
On the street, these power improvements add up to a car that's a lot more capable, especially when passing at freeway speeds. The upper gear range has historically been an Achilles heel for the previous models based on the 2.5-liter n/a power plant. Granted, it's nowhere near as fast as a WRX, but it doesn't feel like you're dragging an anchor, either.
Outside of performance, there are a number of other improvements. The old steel hood has been thrown out in favor of a lightweigh aluminum design; the stock instrument cluster includes an outside temperature guage; the previously optional alarm system with remote is now standard; Subaru's Advanced Airbag system, which includes side-impact airbags, is now stock.

For anyone looking to just get into the Subaru family, or who wants to upgrade from an older model, this new entry level Impreza can hold its own against the field of competitors. And, of course, you also get Subaru symmetrical all-wheel drive, which no other car can offer-that is, unless you want to consider another Subaru."

Sounds like it's faster, lighter weight, and safer. I like haha.

Nice read. Thanks man. I already knew the car was getting AVCS, but an EQ header is really nice. I'm impressed to say the least. An aluminum hood is very nice too. I wish I had one on my 01RS It's going to be interesting though to see wha the aftermarket does for exhaust systems for these cars though. Hopefully they don't just throw these guys on the back burner and forget about them.

So is it a fair statement to say that 2005 is the last year for the RS brand? Or will people still refer to the new 'i' as 'RS'?

That new oil pan....

You can see where the collector and cat nestle.

This is the new Outback 2.5i engine that now sits in my GF6. It doesn't have the AVCS though.

Yeah the 2.5i is 100 lbs heavier than the 05 RS. So much for that 7 hp gain. hahaha
