has anyone replaced there mufflers and or cat/pre-muffler on 08 v-6 accord ?

Someone did a custom Magnaflow setup but we are still waiting for Greddy, Tanabe, Magnaflow, and Borla to release their catbacks. Greddy and Magnaflow are rumored to be releasing soon.

I talked to the guys at Vibrant Performance and they said that they are currently developing an exhaust system for the v6 and that it should be out sometime early next year and Greddy's system is going to be out within the next month or so...

i spoke to one of the guys from greddy and he said the TIC and EVO2 should be out late august if everything goes smoothly with customs and magnaflow (which i like more for muscle cars not tuners) already has a thing up on there site but still no release

I'm just going to wait for the EVO2. Always been a fan of greddy's stuff.

same here!..
