The wastegate HAS to be divided all the way to valve, no if's and's or but's...otherwise you will lose some spool and response. I've also tested 1 gate vs. 2 gates and 2 gates is def the 100% correct way to optimize things and has gains, or should i say no losses.
I really don't understand why people compare everything to record breaking drag cars on here...

I just want to put the best downpipe (or whatever else I need) in my car while I have a lot of it apart.
Just trying to learn.

I have to apologise for cluttering up 4WS' thread but seeing your manifold got my wheels turning and the hope that someday a wastegate version may be offered.

Indeed 2 gates would be the 100% best way but it would be more $$ and more cluttered in the engine bay thats for sure.

There's always sacrifices...i do agree 1 gate is the most simplistic approach
I'll let 4WS' comment more but i have a feeling there will be something similar soon

The manifold looks good, now the OP just needs some dyno results showing any benefits to running a tubular over a stock ported and coated manifold.
$750 for one is a decent chunk of change for it. I am not knocking it at all but some dyno testing would surely justify the price. I like how it looks tho! Just want to see if it performs any better?
