Exhaust Header VS Manifold, which is the better choice?
The key structural differences between exhaust headers and manifolds lie in their materials and design. Headers, like FLASHARK’s B18 headers, are made from lightweight stainless steel and feature a longer, individual tube design for each cylinder. In contrast, traditional cast iron manifolds are heavier and create more back pressure, which reduces performance. With headers, exhaust gases exit more efficiently, eliminating back pressure and boosting horsepower and torque.
Upgrading to a performance B18 exhaust header is essential for enhancing engine output and sound. Whether for track or street use, FLASHARK’s Tri-Y design offers a direct bolt-on solution with no modifications required—delivering better airflow, increased power, and a deeper exhaust tone.

The headers overall are nice, I would recommend them for the price. Some things that threw me off were, the welds on the inside of the flange had some pretty bad undercut and weren't flush with that pipe walls. Also that the pipes were tacked to the flange on the outside and welded on the inside. Otherwise, the welds seem to seal and overall good. Another thing was that the headers are technically 2 pieces and its a tight fit and the 2 bolts hold it together. It was kind of hard to install but that was because I didn't want to remove my ac compressor nor the ac lines. What I did not expect was for the A pipes to be so long (bottom half) its about 10 inches longer than the stock manifold so some modifications need to be done to work with the stock exhaust pipe. It was a bit odd when it was shipped to me because it was wrapped in a thin layer of bubble wrap and the gaskets were free floating in the giant box, so some of the gaskets were a little bent but it worked out in the end.
I plan to get the exhaust here too but that isn't in the budget yet.
Otherwise I think this was a purchase that was worth my money.
For reference I installed this on a 1998 Acura Integra Gs (B18b1)
I wrapped mine but you can see the difference in size between this and the stock manifold.
The flange fit perfectly too.
