you will lose power with a 60mm since the stock exhaust is about 61mm

lol, yeah, 700mm is loud as shit as well. Check out the t1r sparrow 63mm. Gains of 4-5whp without test pipe and its pretty quiet while still giving you the power needed!

70s really aren't that loud - my 3" single is probably twice as loud.

Try true 3" duals on a 350 V8 Chevy with Flowmasters, lol. The vibrations from that shake the metal pole barn its parked in and sets off car alarms as I drive by. Its all in an 83 El Camino.
