Does anyone know where I could find a web site where I can listen to the difffernt sounds of mufflers/exhaust systems. My flotech exhaust I realized was like only a 2" or mabye even 1 5'8s or something horribly restrictive and I must get a new one so my motor and flow better. What size do you recomend and brand etc. Some people say 3" would be ok because I have got the weight "Under 2800 lbs" down further so I could give up some torque for more higher end horsepower. 2.5" - 3" sounds good to me. what do you all think ? Flowmaster, edelbrock,dynomax,borla, ?
