OBX Exhaust Systems

[robokill]

Ok, I did a full measurement of the inner pipe diameters of the OBX exhaust system and its scary.

Header first piece connected to the head. 51MM end pipe

First connection pipe on the header is 48mm ?????

Then you miss the catalytic converter

The end pipe starts at 49mm and the last piece over axle is 56mm

??????? So if I look at the system I would say I can scrap the mid sections and make em custom. That way I can increase diameter of the piping from 51mm from the header to 56 in the end. instead of making the air collapse onto stainless steel plating.

I have to calculate the perfect flow. I guess the first piece and last piece are of good value but the mid sections just suck ...... So if you can weld stainless steel you can turn this into an amazing exhaust but if not Its a good one for a slightly modified engine. But if you really start tuning the flow will be so fucked up that it will cost a lot of performance.

I will post pictures when I mount it to the car and show what kind of mid section I will create
