hi i was wondering if it is possible to make power out of cutting open and gutting your pipes for more air flow? me and my freind are messing around with his old beat up sled trying stuff out before he takes it to the scrap yard.
There is no packing in a pipe,most pipe mods are changing the length of the pipe before the expansion chamber,or changing the outlet size of the pipe, or cannister,it will louder with a gutted cannister,try the other pipe,cost nothing to try since it going to dump anyways
Engines don't really need back pressure. This is only thought because if you take the pipe completely off you lose power. A properly designed pipe actually helps pull the exaust out. Without it the exaust comes in pulses and you get kind of an interference.
