hey mate,
it might be different but i put a new exhaust system on my 2.3TD... It was a 2 1/2 inch sports exhaust system, mandrel bent... It did sound good but only was loud under load.... Yes, it made the car have more power.... just depends because i paid $440 for mine in March this year and that was the cheapest...
Cheers

With a turbo, go for a good size system. If I bought a 2.8, the 1st thing would be a 3 inch exhaust from the turbo back with a couple of small mufflers, provide a bit of a bark but not a drone, the turbo does alot of muffling.

A 3" system can be dear and a pain to fit. I do 2.5" for most things and that works well. A single straight thru muffler will usually be enough.
Then check your boost, factory 10psi, rule of thumb 10psi non IC 15psi with IC. Your blow off valve will release at 15psi which negates your gains so set it at 14psi. A pyrometer would be a wise accessory

I have a 2.5" system (dump-back) fitted to my 2.8td, with a small straight through muffler at the rear. Ideally, you should have a new dump pipe made to reap the full rewards. Didn't notice much of a difference in performance, and the noise level is fine. For $250 I can't complain.

You need a manual boost controller and boost gauge. Although I fitted mine myself, I suggest you leave it to the experts to fit and tune. If you feed it too much boost under load, the EGT will soar and you risk doing some major damage to both the turbo and the engine.4x4 suzi wrote:with increasing the bost on the turbo, how do you do that? maybe i should leave that alone for now as i dont know how to do it...
Fitting a less-restrictive exhaust, in theory, should provide a small increase in boost without too much compromise.
