You can have the wastegate routed back into the downpipe if you like, that will make the sound on existant. Its basically a 38mm exhaust that is flowing the bled off exh gas that isnt needed to make the psi you are running. THe more psi you run, the quieter it will be. The dump tube is the small pipe that runs from the wastegate (which is attached to the manifold pre turbo) to the ground.

The ATP will fit your car and they also have a dp that will fit your car and turbo selection with a vband. The manifold arnold is talking about is probably the same manifold as atp but is a little easier to install. Basically they are identical.

You want to keep the vband. Its a simple connection so if you have to remove the dp, it takes a couple seconds compared to 10-60min with a bolt on flange.

 

So do i need a dump tube? I guess im not understanding what your talking about. Do you have a picture of this? also the .48 is a 5 bolt ford hookup. This doesnt matter though, cause ill have the v-band.

 

You can either have a dump tube which just routes the exhaust strait down or you can hook up the dump to the downpipe and it will be quiter.

You can get a .48 or 63 in a 5bolt, 4bolt, GT, Vband, etc. ATP makes a vband connection that will fit any of the above to their downpipe via vb
and

 

Alright. Is there anything else im forgetting to ask about? I think thats about it except for one thing. Whats a good EBC to use? And are they easy to hook up?

 

I run a HKS, but if I were to change now I would go with a World Racing EBC. If you want my HKS let me know.

 

Hey guys, so i found a (fairly) local tuning shop. They stock atleast the manny and the wastegate for my setup. I emailed them regarding tuning so ill get a reply probably next week unless their open on saturdays. Im hoping they can do the tune for a fairly reasonable price. This would save me the wait to get my ecu back, i would hopefully have it the same day. Id hate to drive out there twice, although their not too far away. Apperently they do revo tuning so hopefully they can do the tune.

 

Revo for the B6 seems to be good, Revo for the B5 and all other 1.8t's..... pass

 

Alright, i'll see if they offer any other tunes.

 

i doubt the manifold is going to have a 5bolt flange on it...

heres the dumptube on the downpipe with a v-band flange for the tial 44mm wg

and my header with the wastegate tube and flange

 

he was talking about the discharge side of the exhaust housing when he said 5 bolt which means its a internal wg housing.
