Rage Big Bore
Saturday, May 17th, 2008With 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.
