Hi.. I have bbk equal length shorty headers... and a mac prochamber on the way... right now I just have some old glass packs... but I'm not sure how these will sound... anyways I am thinking of magnapacks.. but do you think these will be too loud?? any suggestions... anyone have a similar setup... shorties and a mac pro chamber.... what mufflers are you using and what do you like about them... too loud... too quiet???
