! Advice !  Yoshimura 4 to 1 Full exhaust system RS3 Vs Factory Header with Dual Yoshimura RS3 Bolt ons.What is the difference?How much HP Gain?

I have just changed my twin microns with stock headers to a yoshi 4-1 rs3 system.  I have not had the new system dynoed yet but it goes way better.  I will not go back to a twin can system.

 There is also the added advantage of the weight loss as well.  the 4-1 system is lighter than the stock system.

the midpipe is the problem with the stock system . it is a restrictive crossover.

no matter what you see or hear slip ons are just cosmetic because they use the same midpipe. 4/1 pipes allow you to exhaust more spent fuel.

to realize those gains you will need a power commander to load a new fuel map. either get a fuel map from your pipe/power commander supplier or go to a tuner on a dyno.

always get away from slip ons if u want more out of it
