does a performance exhaust pipe really make a difference?

[epyon96r]

Ive looked for a briggs and stratton and I cant find one. you got a link for one? Im rocking a shorty muff Its light, but the briggs I seen was even lighter. Heres a pic of mine




When I make my custom exhaust pipe I will get a better muffler. One of these 8x3x3 or 8x3.5x3.5 or 6x3.5x3.5 or a briggs. something small and light. Oh and relatively cheap, these muffs are less than $20
