External 3 inch downpipe with Turbonetic's Evolution 38mm Wastegate. Its still on the car I and only has about 500.00 miles..$400.00 for both the downpipe and external wastegate.
I'm not sure who made the pipe because it came with this GN I bought..I'm also not sure if it clears the ATR Header but it does have SS headers on it now and clears fine but again don't know the Brand?
