I removed the RB to install the magnaflow on both of my fb's. On my previous stock 12a FB, it had a very good sound, a tiny bit droney but all around a satisfying purchase. On my s/c streetported 13b it was waaay too loud, I "HAD" to add an additional mid silencer and now it is great with the exception of being even more droney than my 12a. Would I recommend a magnaflow, on a stock 12a, sure, any more engine than that, no.

 

Waiting for my buddy to get a new camcorder. I have footage of my car with the rb and will post footage with new exhaust as well.
