By far one of the best sounding exhausts ive ever heard on a 8th gen SI. So deep and when you get on it, sounds so clean and good. No point in spending 500+ dollars just to say you have Skunk 2 or Apexi or all the other good name brands. If you want to spend only about 250.00 this is the way to do it. You will be satisified. I will post up pics and sound clips soon.
