Also would anyone know where to buy a good system from, thanx

3" for sure!

go to your local exhaust shops and get some qoutes. mandrel exhaust or stainless. either way 3" is the best results and they sound great!

ohh and change ya dump pipe. get one with less restriction. sorta defeats da purpose of doing the 3"

Thanx 4 your help mate

Does the bigger size exhaust help reduce EGT's?

Yes a bigger free flowing exhaust sytem helps, 3" is overkill, a 2 1/2 or 2 3/4 will do. To get the best out of it also fit a high flow cat as well.

Hope this helps.

3" would be good for TD42 with turbo right?

SHIT YEAH There is no real need to go any bigger.

Beaudesert Exhaust advertise in A4WDM and I have read plenty of good reports.

I will be checking them out when I do mine.

Hi Peter, what motor do u have

for forced induction id say 3" is the usual i think?
i have a cordia turbo (1.8 4 banger) with a 3"
and most people i have been out wheeling with have 3" for their turbo diesels.
im probably going to go a 2.75" for my trol as im eventually going to go forced induction
