I am looking for a tuned pipe for a big on-road track with large straightaways and large sweeping turns. I race a gas touring car (Reflex NT). On Novarossi's site they list the 51603 as there "top-end" pipe. Here is a picture of it with Novarossi's description:
Here is Novarossi's description: "High speed pipe developed for track use. With this exhaust the RPM range and top speed limit increase giving faster speed in the straights."
This is what I need for the large track I race on (which is Silverbowl Raceway in Vegas). I was given advice by someone to use the Novarossi RB x12 tuned pipe for large sweeping tracks. Here is a picture of it:
Here is Novarossi's description: Roar legal tuned pipe for 1/10th scale on-road racing.
These pipes look very similar. Is the RB x12 just a Novarossi 51603 with the RB insignia on it? Do they differ in performance in any way, or do they offer the same exact performance? Which pipe would be more suitable for a large sweeping track and give better performance for top-end and high-end power? I will be using one of these pipes with a Novarossi 40602 polished Rear Exhaust Manifold, a Trinity/Rossi .12 Pixi-Black engine, and a Trinity Reflex NT.
Also, this question may sound foolish, but is there any performance gains and losses between a "polished" pipe and manifold and a "black" pipe and manifold? Is it just for cosmetics and looks or is there any performance gains or losses between both "colors" of pipes and manifolds?
Does anyone have suggestions on other tuned pipes that are specifically tuned for large sweeping tracks (high and top-end power)?
Thanks in advance!
