An External Wastegate (EWG) allows exhaust gases to be diverted prior to entering the turbo; creating quicker turbo spool. The GrimmSpeed EWG has a larger diameter than a stock internal wastegate; this allows the exhaust gas to be released faster, which improves boost control, maintains maximum boost longer in the rpm range. All of these together will give you a 10-40 HP INCREASE. Moving the wastegate out of the turbo relieves the turbo from the massive amounts of turbulence that the stock internal wastegate creates.
NOTE: Wastegate is not included. Image is only for demonstration purposes.
The entire EWG Up-Pipe is made of 304 SS(flanges, flex, tubing) and has a pipe-wall thickness of 14 Gauge, this is the most "heavy-duty" pipe you will find. Many other pipes use cheap thin steel and are marketed as "super light weight", not us. The inlet size is 1.92" and the pipe tapers down to 1.72 which acts as a funnel as it moves into the turbo allowing for the smoothest transition and best air-flow quality. The one of a kind Triple Layer Flex Joint is not located in the bend, which adds to the life expectancy of the flex section. Our outlet size is a perfect match to most common stock location turbos allowing for a smooth transition into the turbo.
Also available with the EWG Up-Pipe package, is 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. Available for many popular turbos, make sure to add this to your order if you need one.
