Hot Rods best baffles for straight pipes

open to any answers best baffles to use?

 

Cheapest is to cut up some gl*** packs

 

i've used motorcycle ones and the vw chrome tip that comes out of the stock vw muffler.

 

i cut a cherry bomb in half and put in my lakes pipes, it quieted it down alot but its still pretty loud when you get on it. But I havent been pulled over for it so I think its fine.
