Hey guys just wondering if you think i lost back pressure/power from my recent exhaust setup? i got duel pipes same size as original on the VRX and duel red back mufflers and they are running off the hurricane extractors....i have been told that sometimes adding another pipe running can loose back pressure? as a few of my mates have had that problem with their cars... i would take the car for a drive to see any difference but i got no license and no one really drives the car but me and sometimes my dad
