hi i join this forum to have some fun and to get some help with my exhaust on the jag few years ago i cut out the middle boxes and i lived with that for a long time but few days ago i changed the down pipe a bit more oppen one than on the car present so i got very high rpm of over 6.500 but middle range was not as it was so should i put the middle boxes back to get some back presure and gain again my mid range. the question is was it a good idea of removing the boxes in a first place.......?
