It's quite possible to build a front brake kit for the accord considerably cheaper.
www.fastbrakes.com uses wilwood parts which you can source seperately and put your own together.
or you can do a 5 lug rotor over hub swap, use a TL-S/CL-S/2nd gen odyssey 12" rotor along w/ the 12" bracket + NSX/Legend dual piston calipers, or pickup wilwood 4-piston calipers for $100-150/each + a proper bracket.
Or you can build the same 4-lug big brake kit that fastbrakes is selling using all wilwood parts... im not sure how much cheaper it is, but u can source it seperately.
btw noise is probably more a factor of your brake pad choice and a proper installation than big or small brake setups.
