hey guys. so i just bought an 08 wrx a month ago or so and i have a few questions. first of all, the previous owner installed even length headers and an invidia q300 exhaust. the sound doesnt sound too much of a subaru rumble at all. its much quieter. i was wondering if this is from the ELH's or the invidia exhaust. iv researched videos of the q300 and it seems much louder. im thinking its the headers??
