Does anyone have the Perrin Turbo Back Exhaust? How's the sound? fitment? I've been searchin for it but i couldn't find one.
I am looking for the DUAL not the QUAD. Coz i heard that the DUAL has a better flow than the QUAD? Is it true?
BTW i have '13 wrx sedan. If someone can post a link or a clip of the exhaust that would be great. THANKS!
