EXART Front Pipe for TOYOTA Alphard Vellfire GGH20W GGH30W (before minor changes)

This is a front pipe exclusively for Alphard/Vellfire GGH20W, GGH30W before the minor change (2GR-FE engine).
Because it is a horizontally mounted V6 engine, the exhaust manifolds on the front and rear sides are joined at 3→1, and the exhaust manifolds on the
front and rear sides are joined at 2→1 in the front pipe. The 2→1 joining point is in front of the center pipe inlet, and the length to the 2→1 joining point of the genuine front pipe is longer for the front pipe (passing under the engine) and shorter for the rear pipe.
The EXART Front Pipe aims to improve response and sound quality by lengthening the rear pipe to match the length of the front pipe, and by making the angle of the 2→1 joining point acute.
The connecting flange is the same shape as the genuine one, so it can be installed with a bolt-on.
