You already have Cobb, what's wrong w/ their catback as well?
If you want some more help there are some N/A guys at albertasubaruclub.com who may be able to give more specific answers as to what *they* have done. :dunno: |

Cams and exhaust if you want more horsepower.
Then suspension, you can't really go wrong by doing suspension first either. |

yep...
cams and valve springs REALLY help
EL headers do a lot but remove the boxer burble
do either a lightened crank pulley or flywheel BUT NOT both as you will get a check engine light
cat back? anything that's 2-1/4" is best if you plan on staying NA as the scavenging/backpressure/flow is perfect
then get a piggyback such as a perfectpower SMT6, apexi SAFCII, or the upcoming COBB NA accessport
you can also do little things like shortshift and bushing but if you do all of the above you will be able to beat 2.0L WRXs
If you want anything more you need to get into p&p and such. |
