OBX Exhaust Systems

[Project D]

Measure the lengh of each tube before the 4-1: no one have the same...
and it hit the side and the floar (many of my friends, and me included, had OBX header)

I know many people who just think its pretty much bad. Their are bad versions of the OBX that are con artist due to mix brands. The OBX and other E-bay exhaust manifold specifically were pretty much made from
same factory. Tusdo I think its called is pretty much the worst version and much so.

The OBX Catback system is pretty much the rip off version of HKS POWER version. THe major difference is the quality of muffler insulation to reduce noise. HKS use Steel wool for their Catback systems while the OBX ones tend to get louder after use.

People had to rebend or reweld to fit better.

As for the missing part that you used the flex pipe for. You could made a Test pipe like T3 sells. But that flex pipe should do good.

you pay what you get.

got my OBX header fitted few weeks ago, I dont have any big problem fitting them only small problem with EGR connector. BTW I broke the EGR pipe after trying to bend it and finally take the decision to remove the EGR after all. So I solved my problem. and hope no problem with MOT later on.
Got test pipe on it and HKS hi sport. I heard OBX header got problem with horse power reduce or something. I dont know.

Ok OBX measured at the track. Noise was 93.4 DB with open air filter. I am looking into removing the jap style tip and placing a normal oem look damper.
