Thanks rcdad for the longest I was told and thought that a silencer took power away from the pipe boy was I ever wrong so dino had me tune the motor with the pipe and the silencer once it was tuned right and running great he had me remove the silencer of course it rand like crap so I had to re tune for just the pipe and it rand good but not as fast and as much power with the silencer so of course I put the silencer back on and re tuned and its a absolute beast!!!!!! They say you learn something new everyday I didn't quite understand what dino was explaining but he said it has to do with more chambers and more power getting on the pipe because of the silencer which allows for more power. Something like that.
