tubular headers for classic
here we have my tubular headers done around 13000miles in mint con (apart from 1 fixing stub broken visable in picture) there slip jointed and not the cheap sort that leak and blow unsure ov make or brand tho very well made with no sign ov cracking like the cheaper items £SOLD
pm call or tx cheers

broken off stud visable this is mounting point too block not turbo

Heres a link to a thread on 22b.com.........Syms 4-2-1 headers.
Just waiting to get mine fitted and mapped.....

EXHAUST HEADER WRX/22B
SYMS's has arrived at a total tuned exhaust system. When the cylinder is in the exhaust position, the other cylinder's inhale or exhaust valve gathers at the exhaust manifold opened, the exhaust gas energy wouldn't turn the turbine and would escape to the cylinder. (= blow down) It needs the "4 in to 2 layout" to prevent this from occurring. SYMS exhaust manifold has been completely designed for the exhaust system through pushing the turbine by its joined front side CYL 1 and CYL 2 and the backside of CYL 3 and CYL 4. These are then forced into an independent stage, until just short of the activation of the turbine. Therefore dramatically increases the engine ability to spool up faster at lower RPM. When compared with other exhaust manifolds, SYMS uses narrower pipe compared to other exhaust manufactures especially the primary. The reason for the narrower pipe is to speed up the flow of exhaust gases. (It is common knowledge that smaller diameter pipe do two things. 1-Exhaust gases speed up. 2-Helps maintain high exhaust gas temp to improve flow.) Also, the flange is part of the air-funnel, forming a smooth connection with the engine's exhaust port. SUBARU's engine is all made of aluminum. Therefore, the port-flange-span changes 2-3mm between cold and hot. It needs the sleeve-flange for absorbing the changes in the span do to the expansion of heat. A slip-joint of double structures has been implemented that consist of an airtight-slide-sleeve for the savings in endurance and high-pressure exhaust gas.
