This is the Novarossi 9853 'Super Strong' polished racing pipe (no manifold). This is the one piece variety and requires an off-road manifold, which attaches to the tuned pipe using three small springs (not included). This pipe is designed for excellent bottom end/mid range performance and is a great pipe to bring the bottom end to life on Novarossi 421B engines. This pipe is an excellent choice for any engine that works well with a 053 pipe. The 41005 header is an excellent choice for this pipe for strong bottom end power delivery, while the 41001 header is recommended for better mid-range/top end performance.
With the brutal environment of 1/8 off road racing it can be difficult keep any tuned pipe free of damage. A damaged tuned pipe will hurt engine performance and can be costly to repair or replace. So now, Novarossi offers a "Super Strong" EFRA 9853 tuned pipe, which has been built with thicker material to take the abuse of serious off road racing.
A positive side effect of this new "Super Strong" pipe, is that it resonates at a different frequency, which makes this pipe quieter than the previous Novarossi 9853.
NOTE: This is only the tuned pipe, and does not include a 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.
