I have a 92 da with a jdm b18c1(GSR) with a Shunk2 intake manifold and throttle body. RSA headers.(tuned) Nothing else done engine wise. Should I go with the HKS Hi Power cat back or a custom 3" mandrel bent exhaust with a 3" magnaflow muffler. My friend has the 2nd opition and sounds ok, not to raspy.But just seeing what everyone thinks. This is my daily driver. I drive about 25 miles one way to work. ALL highway.

3" is way to much for that setup, if it’s stock like yours your should be ok with 2.5.  
I have buddies running B20v setups pushing 250 HP all motor running 2.75".
