Fabspeed vs Tubi Header for F355 GTB

now those are nice. I’d pay for a set of manifolds that look like that.

 

Sounds nice.

Dyno graph needed.

 

Thanks. This is the latest after shortening/straightening the intake trumpets.

Clean, smooth, not overly rich.

Nicely done.

 

Thanks. Just by luck really it's just the stock 2.7 motronic ecu's. Nice that the maf's had enough overhead to compensate but makes sense I guess since they used the same ones on the F50.

 

So 5 more rwhp from the last dyno…

 

Yeah not much but always happy if it goes up instead of down
