http://www.grimmspeed.com/catalog/product_info.php?cPath=22&products_id=121 An External Wastegate (EWG) allows exhaust gases to be diverted prior to entering the turbo; thus creating a quicker turbo spool. GrimmSpeed’s EWG has a larger diameter than the stock internal wastegate; this allows the exhaust gas to be released faster, which improves boost control, maintains maximum boost longer in the rpm range, and extends the life of the turbo. Moving the wastegate out of the turbo relieves the turbo from the massive amounts of turbulence that the stock internal wastegate creates. The EWG Up-Pipe is built from 304 SS with thick 13mm 304 SS flanges. A flex section has been added; this will extend the life of the product(allows expansion/contraction of pipe without cracking) and will lead to less exhaust leaks. Users should expect gains in the 15-40hp range when tuned for the EWG set-up. Also included in the EWG Up-Pipe package, a bracket to hold the stock internal wastegate shut. This bracket is helpful because the turbo door does not need to be welded shut, decreasing the chance for leaks and allowing for easy removal if necessary. The GrimmSpeed EWG Up-Pipe Kit fits more downpipes than any other EWG Up-Pipe on the market. Quick Facts: Quality Flex Joint - We've sold well more than 600 pipes with flex joints and have only had at most, 2 issues with the flex joints. Flow through Flex - There are no big steps in the flow path of our flex joint. Our flex is not located on a bend so there is very minimal flow loss(if any) through the flex. Curved EWG Side Outlet - Our ewg up pipes come with an angled side outlet which allows us to obtain optimal flow to the external wastegate, 2.0mm Piping Thickness - Almost all pipes on the market use a 1.5mm thick piping wall, not us. We use a 2mm thick piping wall(33% thicker than all of our competition!) Pipe to Flange Connection - Much smoother connection. Piping is ported flush with flange so there is no step into the pipe. 1.92" Inlet - Perfect match to gasket allowing a little room for gasket movement(anything bigger, ie 2", will almost be guaranteed to put the gasket in the flow which is horrible for flow). 1.75" Outlet - Narrowing down from 1.92 to 1.75 acts as a funnel. Also very close match to most common turbos so you have much less step going into the turbo(unlike a straight through 2" which creates a huge step going into most common turbos vf's, tdo4s, etc) Massive 304SS flanges - These flanges are beasts in person! Complete stainless steel construction (pipe, flex section, flanges). Flex joint that is NOT located in the bend which adds life expectancy to the flex section. many other up pipes have a flex right in a sharp bend so all the exhaust/turbulence is hitting up against it. Even fits large TurboXS 4" Bellmouth Downpipe!! Which means is will fit almost every single downpipe on the market. New Tial 38mm V-Band compared to current Tial 44mm V-Band.

uh yeah, duh, when 90% of the community uses tial and want to see how it mounts on there, why not? A picture without the tial shows the pipes but not how they are connected with an EWG, everybody wants to see how it connects, therefore showing the EWG not only shows the pipes BUT also shows how they can be mounted......
I think the point Shibbs was trying to make is, why aren't there pictures of it with AND without the wastegate attached? All the pics show it attached, which gives the impression that the pipe comes with the WG, which isn't the case.
You're only option is the Tial. They are the only ones that make a 38mm Vband WG right now. Wastegate is sold seperately..the Tial is 259.99.
Holy smokes, $319.00 for the pipe and the wastegate is a STEAL! I remember when I was looking at going EWG, I was looking at $600+ with everything.
Just started the Nasioc group buy on these! http://forums.nasioc.com/forums/showthread.php?t=1785577 Get them at a super low price before it's too late!! Mike
