Earlier this week I took my 95 Civic EX in to a muffler shop to check out an exhaust leak. The tech said the resonator is rusted and cracked, as well as most of the pipe from the cat back. I figure now is the time for a modest exhaust upgrade. He suggested a performance resonator ($75), a Magnaflow muffler ($120), and 2.25" pipe. With labor he quoted $391. Does this seem like a reasonable price? Any suggestions for alternative mufflers (I'd like to see a little hp/fuel economy increase, but really don't want a loud system)? And is 2.25" preferable over 2" (car is stock besides the CAI)?
