magnapacks are ALOT louder than magnaflows. to get the sound of magnapacks when using
magnaflow mufflers, an off road h or x pipe is definitely needed. however, i think when an h or x is used with magnapacks, it is FAR too loud. my friend put an off road x pipe and magnapacks on his 03 GT and you couldnt talk to the person in the car with you at a normal voice, and this is shifting at ~2000 rpm...it just gets louder above that. personally, i think all magnaflow products are too burbly, almost sound like the car is under water...except at WOT. im thinking about swapping my magnapacks for an SLP loud mouth cat back. the SLP gives such a great muscle car type sound, IMO....
