About a week ago I made a thread asking about an exhaust. Here's the link: Exhaust
This exhaust cost me $110 (cheap) and the results were amazing. I installed it and recorded a video (a bit bad quality because it was recorded with phone). I will try to make another video which includes the inside, with a GoPro camera. Will post it in a few days. Here's the video:

I would recommend it to whoever wants something cheap and great for the price, until you can afford a $500+ Exhaust.
Ps: Silencer was removed. (Looks like it has it because of the angle, but it doesn't)
