You would be fine with any 3 inch piping exhaust back to the muffler with a free flow muffler
tks for the advice.. i figure i will give arma a whirl with their "specially tuned" exhaust.. i can get a 3 inch exhaust but in china, it is best if you stick with finished products.. custom work and quality isn't exactly a strong suit here..
