do you want loud? the manta being off the shelf is probably quiet bu louder than stock

i had a similar system years ago and the sound was great but it was quiet

i replaced the mufflers with hot dogs and it was better
then fitted a lumpy cam and deleted the h pipe and it was crazy loud

if i did it again i would stay with 2.5 duals with 4in round 12in long resinators in place of the mufflers and do a cam swap if you want it to idle like a v8
