Tried Hot Bits 4-2-1 extractor for CPS!

Recently installed a 4-2-1 extractor from hot bits on my car and the result is amazing. The extractor improve the low and mid of my car while maintaining the high end power. If you observe the picture below you will find that the length of '4' is all equal and it's about half of the length of '2'. From what i know this is the best setup for 4 cylinder engine so it's a good buy.
