Just like the title says, I go back and forth on what exhaust I want to buy...two of my main focuses are the Greddy Evo2 (side note the 98-01 subaru impreza 2.5rs cat back would fit an 06 correct? I was told their is only a one hanger difference that does not even make a difference?) and the Stromung single 3.5 inch tip. Whatever I get will be Stainless Cat-Back system...Any thoughts on sound comparison between the two? I want the boxer rumble, and I want it to sound mean at WOT, so I'm not looking for something whisper quiet. I don't want a civic-esque fart can than sounds like WOT at minimal acceleration either though. Any ideas of the highway drone? WOT? Boxer sound? Any other reccommendations? I've looked at both the OBX and Rallitek (I know they are the same for all intensive purposes) setups as well, but was not too crazy about either...Any help, opinions, thoughts would be great. Thanks ahead of time.

 

You won't be able to get that boxer rumble due to our equal length headers.
As for exhaust, I'd go for Stromung. Stromung attemps to re-create the boxer engine rumble. If you want a loud engien at WOT, get a CAI or short ram as well.

You might as well get Stromung catback + Obx EL headers + Injen CAI or Weapon R intake.
