If you put a straight pipe on the inlet of the turbo you could dose like a VL turbo...... Ssssssss 2 2 2 lol

I loooove that noise! Cut out the muffler and WOW! It's awesome! Well on a TD42 it is anyway ;)

Some people believe its bad for the turbo. I can understand if your running 30 psi but on these low pressures i doubt it has any effect.

I know its awsome. mine heaps louder now the boost has been wound up

i have come across this problem about four times now seems to be common problem but sometimes a slightly different sound. you need to check the first exhaust manifold port for signs of black soot sometimes this is very hard to see get a good light and check over the whole manifold area they usually have a broken stud sometimes they look ok but there broken. because of heat sheilding it is very hard to diagnose. in most cases the manifold will need machining and recommend changing everything studs, gasket anything thats hard to get too.

Hope this helps sounds like a few of you have this problem.
Cheers Alex
