Think i'm getting 450 hp or am i being to unrealistic?
What you could do is install a FM 3" to 4" y-merger, then into a 4" electric cutout, then a 4" to 3" reducer back into your 3" catback. This way you will have 10-15 more hp available when the cut-out is open, but when you want to just cruise again with a mellow exhaust tone you just flip a switch.
