This is the Novarossi "Super Strong" EFRA 2084 One Piece Tuned Pipe. This pipe is essentially an EFRA Legal 3-Chamber version of the Novarossi 9853 pipe. This is an excellent pipe for 1/8 truck, as it produces power similar to the 9853, while offering the smooth power delivery, exceptional top end and efficiency of the 9901. The 41005 header is recommended for smooth power delivery, while the 41021 is the header of choice for bottom end power delivery.
NOTE: This is only the tuned pipe, and does not include
manifold, manifold gaskets or retaining springs which must be purchased
separately. This pipe is made available as a separate item so you can
choose either the long or short manifold, depending on whether you want
better top or bottom end performance.
