my car is a 2005
apparently these cars are completly different from other cars ive messed with.
so i should be fine with full exhaust without a tune for a while? any CEL's that will likely be triggered?
i couldnt find any info,and yes i searched.
is a tune really NEEDED for a exhaust system? i've messed with a few cars(mustangs,srt4s,focus's)but im new to subarus
