Riddle0288

Just picked up a 1 chamber flow from my.buddy for $10 lol i have a custom 2.5 y pipe to 3 inch to a slp2 dump before the axle sounds amazimg but always loved the tone that a 1 chamber gives.. my question is i see alot of ppl run dual 1 chambers on there ls1's.. y 2? I have heard these lil mufflers flow real well an can handel like 600 hp or somthing like that.. is it just for sound? 2 sound better then one? Idk but was just going to put it in place of my slp with a dump.. my car has 228 cam, has full bolt ons an 1 7/8's headers.. made 396 on a dyno
