I recently pruchased my Eclipse with a 2.5 DP and 3" back, no cat/flow thru Magnaflow. It is too damn loud. I recently went to a local shop and they claim a hi-flow cat will quiet it down a bit. What I would really like is a baffled style muffler 3"in/3"out and make it atleast 1/2 as quiet (I really wouldn't care if it sounded near stock). Does anyone think this will do the job? ...And even help on my boost creep?
