my friends dad talked to one of the local dealers about pipes and he said cheaper ones like cobras and mine are packed loose and if u put more packing in u get more power and quieter sound level.is this true?i am getting the packing tomorrrow and i am going to try it.other ppl have said i wont be able to get anymore in.i will let you know how it turns out.i am just going to add more not redo it all.

 

I bought some DG packing stuff today,i removed the tape on the current packing and added about half of the DG stuff.then i taped it all back up,alittle less noise,not much but its doesnt backfire at all now .alittle power increase also.
