That was excellent I had a look at those exhausts. I've been doing some research and I can't find how much each increases performance. Do you have any suggestions as to where I can find this information? I'm really interested in the Mugen sports Exhaust, the Fujitsubo Legalis and the Amuse Titan Euro so far. Leaning towards Mugen because I like the sound however, I need to strike a balance between performance and sound/loudness, and also I need to consider that it is suitable for future modifications to the car.

Yes I'm a noob, shut up, leave me alone.

I went to JDM yard in Syd, they suggested maybe Fujitsubo Legalis. Thoughts?
