could any one please tell me where i can get larger
dump pipe (ie 2"-2.2") in QLD. i run a 2" system with
a hot dog. i figure matching the dump pipe will help
the bottom end. a phone number would be good.
any help is appreciated....
oh its a 2.4 turbo diesel surf 94 model.....
running 32" big horns 3" lift....

try any exhaust shop. It's not a special fancy job at all. Cost you round $150-200

The best results are from a 3" dump with 2" rear and free-flow sports muffler.

Beaudesert exhaust actually take off the back manifold of the turbo and custom make the dump pipe to fit the turbo.
You would be surprised how much more this opens it up as it does not get restricted coming out of the turbo.

spoke to local exhaust shop, they said a 3" dump pipe
wont bolt up, (it will but cant get in to do nuts up on back of waste gate)...
he suggested go 2 1/2" from back of turbo strait through!!!!!
i dont no much about surfs but i suppose that would work ok
to me.....

The exhaust shop is right to the point that the exit from the bolt on exhaust housing on the back of the CT20 turbo is barely 2.5", can go bout 30-50mm of 2.5" pipe then 3" for bout 1m for more room for hot gasses to expand into followed by 2.5" or 3" pipe to flex joint + a good flowing muffler (sounds better without one tho).
Better again would be the replacement of the bolt on housing on the back of the turbo for much better flow which can be bought from Eng-tec in Werribee, Vic.
