Dyno results of prototype 1.625 primary 4-2-1 Catted Header with full exhaust:

Combined Data (note that lower peak modded run made 29hp vs. the lower peak power baseline, albeit at the very top of the range). Needless to say, once the tuning solutions start popping up, this header will support some serious top end capacity...and the catless versions should do even better based on their ability to run more appropriate, longer, secondaries:



Horsepower Alone:



Torque Alone:



Gains in HP/TQ and % Increases:



(note, these graphs above are still for prototype parts, we're pretty confident there is more power to be had with other configurations that we will be testing very soon)

Weight Specifications:

Factory Header w/o Heat Shields: 15.0lbs
Nameless Performance Stepped 1.625-1.750 Catted Header w/o heat shields: 11.6lbs
Nameless Performance Stepped 1.500-1.625 Catted Header w/o heat shields: 10.9lbs

Wait, just to be clear : I read Up 46ft lb and 36whp in the dip (with a full exhaust)

DAAAAYUM !

Hope this becomes available in Europe

nope, looks like the dip has been shortened and moved back earlier in the rpm range (still a big win IMO)

I'm wondering what's the best placement for a cat for performance and sound. Header or front pipe? or both?

Frontpipe/downpipe

^You don't want it in the header because it reduces the ability to have the proper radius bends on the secondaries.

I've never heard of a cat in the header. That's a new thought to me... MAKE IT WORK!

[FR-S Matt]

I just don't understand why there's a need to restrict the most important piece to the exhaust when 1 cat is sufficient enough in the front pipe. I've never owned a catted header nor do I ever want one. The whole point of a header is for the engine to breath better, right? One cat is necessary though... I cannot stand catless rasp.

Our stock header has a cat

Pretty much all new cars have cats in the headers. The closer the cat is to the head, the quicker it warms up. This results in a significant improvement in cold start emissions.

If there's room for a turbo down there I don't see why it shouldn't have cat for those with N/A who want to keep it as clean as possible?
