Optimal performing exhaust for street

The new fujitsubo header would be my easiest route, but the true equal length sure looks cool.  Which is my goal.  There is zero wrong with my current header.  

I contacted star road and spirit garage.  Asked both about bolting up to the newer style fujitsubo exhaust.  

So your Fuji is like the GreddyTrust shape? Looks like an equal length but it’s not really . I’m looking at a used Greddy and looks identical but it’s blue :). 

Let me know if you decide to let yours go. I just want something that has side by side dual outlets . Currently have the MSA .

I don't know if it's a greddy shape. I would say it's not equal length.  

 

It is ceramic coated though.

I'm curious to see if this discussion gets anywhere with tangible results.  I hope it does.

This kind of request comes up on other forums with much larger viewership (Mustangs, for example).  But few people dyno test multiple exhaust systems on the same car.  And it's pretty common for there to be other, competing priorities, such as cost, fitment and sound.  So it's usually "I bought XYZ and I like it" from about a dozen people.  Still, I'm looking forward to the results for when I upgrade mine.

Real results would be dyno time and lots of headers. But I doubt that would ever happen. 
 

So many variables, I think it would be impossible to really test. 
 

cams, port work, compression, engine size, exhaust size, carb size, efi or not etc......

Fujitsubo have clear dyno's for their new system and the old type.

Looking forward to seeing / hearing that Fuji system on yours when you finish your car, in 2032! [emoji12]
