Some where I saw a cut away of the mufflers of the 1300 R exhaust system... trying to find it again so I can see where the holes i have drilled into them are opening up.. I noticed today when i was looking into it there was tube that is capped off and is where one of my 1/2 holes were.. I was felling drill happy so I opened that tube up as much as I could.. Bad a nice improvement. looking in to hole i opened up it appears to go a long way back. I was wondering if i have opened up the main tube coming in from the header pipe.. Thats why i wanted to see the picture..
Any direction is welcomed..
