Rage Big Bore
With my car stepping up in the power stakes i now felt my single 2.5″ exhaust system was getting restricive - so i did a little more homework and after finding some back to back dyno tests carried out by Rage exhausts i decided a single 3″ Rage system was to be the weapon of choice.
Some say a single system acts as a better scavenger of spent gasses from the engine over a smaller diameter twin system.
I had my local exhaust shop do the fitting and i was very happy with the result…..a much better exhaust note and even more power…..the power bug has bitten and wont let go!!
The following link is very interesting - its an independant back to back dyno test on a standard VY SS Commodore….i will let the results do the talking:
