i have a 3inch turbo back right now.... if i was to take off the axle back and make the stock axle back fit... would it sound stock? like... almost no rumble? i had the stock cat back on my 3inch downpipe before and it was damn near stock... no rumble, but i did hear turbo. wondering if the stock mid pipe has much to do with it.....

 

It will sound close to stock, but a little louder.
