[QUOTE="whenfoxforks-ruled, post: 1191493, member: 73147"] Well I talked to Dave yesterday(2 1/2 hours!)then I seen this thread about this guy's shifter cart that will probably frag a piston due to changing exhaust pressure and he brought up his idea about putting barriers inside the pipe to force the sound waves back in line with the pressure wave!I was like my jaw hit the floor,of course this is beautiful and why has this not been done before!Or has it,once installed who would know its there?
