Okay i have been reading about what muffler to get for about an hour and still can't decide. I have a procharger and i am running pacesetter longtubes with ORY to a flowmaster 40 series dump and i want to put in a cutout would it be just as good to put it right after the y so i only have to use one cutout or should i come right off the headers and use 2 cutouts. I also want to change my muffler to a magnaflow but not sure which one to get ive been reading for a while and i decided on a magnaflow but i have no clue on which one. Thanks in advance guys

 

2 cut-outs would be alot cleaner and efficient than the one after the Y. Also good move on moving away from the flowcrapper, I'm surprised you haven't dislodged any baffles yet seeing that your FI. I'm not a muffler pro so I'll let someone else answer which one to get but Magnaflow is a good move!

 

choosing a magnaflow muffler is all about how you want it to sound,larger=quieter

They all should flow the same no matter the size because they are straight through mufflers.
