I have a 2010 xc60 t6 and I'm looking for guidance as to what I can do as a fairly cheap way to make my exhaust louder without doing a full straight pipe? Any help is much appreciated.

 

I had a custom cat back 2 5" exhaust made. I repalced the resonator with a straight through 24" Magnaflow round muffler and put another 12" straight through Magnaflow behind the rear axle. Not to loud at idle or cruising around, but she sounds epic at full throttle. A nice bonus was I picked up 2mpg on the highway.
