hey i got another 300ex tha otha day and i dont want to spend more $ and buy a exhaust. i was thinking of takin out the baffle and jammin a pipe through/smashing inside. has anyone done this or tried this ? or has anyone modified it at all for more power/loudness? :confused:

i tried to get the baffle out but it was spotwelded and i couldent get it out so i just drilled holes in the bottom. I put 7 of them in and if u do it this way just put 4 of them towards the end of the muffler and maybe 2 of them towards the head pipe. I used a about a 1/4 inch drill bitt. Its pretty loud and gave me more bottom end.

DO NOT take any thing out or drill holes in any thing. IT WONT DO ANY THING BUT MAKE IS LOUD AND ANYOING. NO power gains.

i said f IT and am jus runnin a header now. LOL j/p. no no i took my air chisel and chisseled them spot welds off, popped out the baffle and it wasnt much louder. SOOOO then where the pipe get big there is a weld. I took a grinding wheel and cut that weld all the way around. HOwever the end of the pipe will not fall off becuase it is still connected from the inside as i did not grind completely through the entire thing, just half way. THen i put a couple of spot welds around it to make it more rigid. THE THING SOUNDS NASSSTYYYYYYY. SOunds like a combination of a HMF and FMF megamax. The thing is it looks completly stock and sounds nasty AND if i want to make it quiet i can just weld that weld back up. and it will b stock again. I will post pics if u guyz want me too but there is not much to see as it looks stock.
