Hi

If the 3400 has the same U-bend for the secondary O2 sensor as the L36 3800, than you can cut the pipe and install a straight pipe with a bung for the sensor. That should yield about 5 hp.

Not many performance options for the 3400, but I would do a UOA just to make sure she isnt leaking internally.
