who made it? how much does it cost? does it affect so much to the performance?
It cost probably $1500 with downpipe and wastegates. I noticed slight performance gains over the old log manifold, on the VET cams. Spool was a lot better. Most guys see slower spool and 40-60whp increase over a log manifold depending on turbo/engine/cams etc.
It was made by a local shop Element Racing. Made from SCH40 stainless pipe.
What about getting a 5557? or the 5857cea thing. will pack a lot more punch than the 3076r and loose minimal spool. the 5857 with the cea wheel should be gt35r territory
