i expect there will be a slight increase in power, there has to be, the gases are flowing a lot more freely, i cant say as i can notice it though, the sound itself makes the job worth while

So the only point that exhaust isn't just a pipe is the main cats or are those gutted too?

Sorry I want paying attention.

Is the whole exhaust made from before by yourself? Or just the mod that you done?

If its the case that youve modified another exhaust, what was it before you chopped off the box?

Lookis like it was a single exhaust? What brand? or completely home made?

i have a hangover and your confusing me saf! the back box splits from the mid section there is a sleeve that slides over the pipes holding them together there is no cutting involved, jus undo the 2 bolts on the sleeve that holds the mid to the back section. before i did this my exhaust was standard the pipe is 2.5" standard.

cheers dude.

its quite simple if u have the tools and equiptment. stainless tube, stainless bends and a tig welding set, i removed the original back box and basically used the bends and tube to create 1 piece starting and finishing at the same points as the standard box. measured where all the hanging brackets were and made these with some 12mm bar.
i hope this sort of explains it
