I installed this on
Mitsubishi Evolution

Review
I had noticed a significantly fantastic boost in my car's performance upon replacing my stock exhausts with these Fujitsubo Authorize R. Power had definitely increased, judging by how my car accelerate - quicker and smoother. My throttle response was also much responsive. Along with all these goodies are the sweet sounding bass-acoustics. While idling, it gives off a light, almost silent low tones, but upon hitting the gas pedal, it blasts with powerful acoustics!

What I like
I love this muffler for the performance boost it has to offer, along with great soundiing bass.

What I do not like
Goes for quite a hefty price.
