u should read through all the threads in aftermarket exhaust along with OEM that are about louder exhaust.. there everywhere.. basically ur gunna be told to run true duals. get urself 2 hi flow cats, an x-pipe, get 2 11 or 14'' magnaflow mufflers or just keep ur si/do muffler if u want(but it wont be true duals) and run 2.25 or 2.5'' piping..
if u dont wanna do that, then just get a louder muffler (flowmaster 44 or 40) or a 14'' maggie (unless urs is a 14'')
as for ur tips, not sure.. how old r they.. clean em with sos pad? or get new ones maybe. i wouldnt spray them with anything but maybe theres somethin out there that will help.. i dont kno personally.. TIM
