As it is a 2inch piping setup, it serve me very well in acceleration especially in the drag race of Johor Circuit. But as I hope to focus on full track setup for my car, it will be better for me to up-size to 2.3inch piping which will be much better to match with my future plan. However, this 2inch setup is very much recommended for any standard B16A for street performance combine with some track session.
Both the header and the muffler are made in Japan, and the header come with a JASMA tag which means it fulfilled the Japan authority road legal requirement and built quality. The Border 304 does not have the JASMA tag as it is a race spec muffler, with high power output and sound level which is not legal to use on Japan public road. Both of them are in very good condition, the header has minor repair outer face which will not affect the performance at all. For those who wish to take the extractor and muffler together, the center piping with 2 center bullet will be given free! This setup is still roaring on my car and will be taken down June or July when my new 5Zigen Pro Racer extractor arrived from US. If interested you are very welcomed to test it on my car! It will be plug and play on Civic EK4/EG9 4doors or any other B16A with minor mod.
