Bought my JDM ITR header tonite, got a carsound hi flow cat here (2.5in/2.5out)and now im looking for a good catback. Ive had my eyes set on a stock jdm itr (2.5") or the rs-r exmag. The exmag is $$$ though

any cheaper ideas?? I want QUIET! NO fart pipes and prefer not raspy.
im a sucker for nismo if that tells ya what my tastes are haha
