Default Help!!!!

How can i get more HP out of my 08 2.5i? I have the SPT cat back exhaust and planned on getting the intake but just learned today that they will not be making one. They said it makes the engine run too lean! Am i out of luck or is there something else i can do!?

there isn't much you can do to extract more power. even with all the bolt-ons you can think of, there isn't much to be gained. unless of course you want to buy a new exhaust/trans/longblock to swap in.

For best results:
Step 1: Sell car
Step 2: Buy used WRX/STi
Step 3: ?????
Step 4: Profit!

nice southpark analogy. I dont know much about the new "i" motors but have u thought of going with cams, heads, full exhaust, and higher comp ratio? Like I said from reading other threads there isnt much out there for the "i"'s but good luck.

Hi all, I'm new to Nasioc and a kind of new subbie owner. I'm just like rposton21 where I have an 08 impreza but mine's an outback sport.

Where did you get your OEM exhaust rponston21? I didn't think SPT made those yet for non-turbo impreza's.

Also, anyone know where I can get OEM parts to increase power between 190 - 200hp but only n/a? I've been asking around car shops that can tune and they said that there's not much for n/a subbies out there..

There are no oem parts to increase the power output to that point, unless you count an engine swap.

i got the exhaust from spt they make it for the wrx and it works on the 2.5i. it sounds real nice and low but its not super loud...for me its perfect! it depends on what you are looking for!
