Any change in the sound level from just the downpipe?

 

No they go right where your downpipe is now.

If it was on the exhaust manifold you would lose turbo spool/power.

 

Uhhh... what???

 

This is how an external wastegate is setup....

 

Hahahahahah.... oh jeez. Sorry for the thread jack regarding EWG vs IWG Phantom... I can't stop laughing at this picture.

 

on the ets divorced o2 downpipe the wastegate goes right on the divorced part. on a t3 exhaust manifold it has flanges built in (either 1 or 2) for the wastegate. i have the full race exhaust manifold that isnt t3 design and doesnt have flanges for a wastegate and i have the ams o2 downpipe with is widemouth with no divorced section for an external wastgate. better? lol sorry if i was vague before.

 

You shouldve waited til your car had 3k+ miles...

Its not broken in yet and your modding it...

 

I bolted most of my stuff on at 1200. Tuned at 2k. Going E85 tomorrow at 4200, which will max out the stock turbo.

Haven't changed the oil yet but that's on this week's to-do list. It's a machine, not an egg.

 

Wait your at 2k miles tuned and you havent changed the oil?

 

Thats the point of a wastegate, to limit how fast the turbo spins and let some of the exhaust flow past/around the turbine.

An external wastegate can go on the Manifold OR the downpipe...

 

^^ +1

 

Ummm WHAT again???

OR?

An external wastegate that's on the downpipe and not on the manifold, explain to me how that's gonna work please

Where is all this "information" coming from?

 

^^ what he's saying is that the other option to run the external wg is in downpipe section..you can check this out

No prob, now I am curious to how a wastegate on the down pipe would even work. Since the gases going through the down pipe have already left the turbo, and are on their way "out of the car" how would it do anything to control boost.

 

Wtf, that's not an EWG man...

That's an IWG with a divorced outlet... the EWG on that is after a welded/gutted open IWG.

Phantom, it's not possible for that exact reason. External wastegate must come off of the manifold and from there it can either dump to atmosphere or it can re-join the exhaust at any point (typically on the d/p).

Edit: But I do see what you mean with an EWG coming off of the IWG.
