More backpressure/torque compared to a 3", a little quieter, and I don't believe that Ben has a downpipe yet.
2.5 isn't as deep sounding to me though. with 2.5 you might lose some torque down low but our cars already have plenty of that. 3'' gives expands the torque curve longer in the mid and upper ranges. Its just a better powerband all together imo. APR used 3'' all the way and yet we let them tune our cars so they must know something. If you ever want to go big turbo your already prepared. Quite frankly I hope everyone buys everything except what my setup is, just so I'm the only one that has it lol.....
