i have one kinda lol. we taped all the holes and pluged them and got rid of the butterfly. if that would work i might be able to sell. its my only exhaust but might be able to find up some more for cheap. i want headers anyway.
edit: actualy i think from your pic the pass side is the one that is modified a lot. i will check out the drivers side monday and see what al we did to it. if its just taped it might work good
