exhaust question
 

More out of intrest, the downpipe on my is as far as i know is the one it came with when it was imported.Would it be 3" (all of the downpipe )as the rest of the system is??
And if i wanted to just change the back box would i have to buy a 3" one???

if your pipework is 3" then you will need another 3" to mate..............

as for the d/pipe a lot have a 2.75>3" convertor............
