Both cars are on Ethanol (E70?), JRSC, HBP. Same dyno, same tuner. CSG's BRZ overlaid onto the official JRSC HBP dyno.

Is there a TLDR version of the differences between the types of headers? I noticed how there are like 6+ different types of headers on CSG's site

A = original
B = slip fit version designed to reduce production time and cost, while A style headers were being finished.

B headers are nearly identical in performance, but are not as smooth as the A internally, and are being phased out.

150/250/350 = merge collector type. 350 has the fattest overall powerband, and has proven to also be the most popular.

A/350 is what CSG originally tested.

The CS/400 is a B style construction with even more low end power.

We have an A/400 final prototype that is currently at the ceramic coater, which will be validated, and then that will also be production ready...

TL;DR: buy the A/350.

Thanks! I was originally looking at the A/350 on your site already. Through deductive reasoning, the more expensive one seemed to be the one I picked (which you mentioned, better) and I applied the "you get what you pay for" here. LOL you'll see my business shortly in the next couple of weeks!

These are the test results on @Jmonty 's JRSC C38 car. THere are 3 graphs on one plot, so pay attention! Torque is left, hp is right graph.

Dashed blue line: stock exhaust and his previous custom header.
Dotted blue line: stock exhaust and the Ace 4-2-1 header. As you can see, lots of low end gains (particularly below 2500 rpm and from 3200 to 4200 rpm).

Solid green: Perrin 3" exhaust with the Ace header. As expected, the exhaust did basically nothing (not unusual on an S/C car).

The general concensus with the JRSC owners is that the Ace header really, REALLY fattens up the power band.

Remember, while the JRSC eliminates the torque dip, the dip is eliminated because the torque curve is being "tilted" counterclockwise. It's still there, but just covered up by all the gains from boost. Add the Ace header gains to this, and it becomes really, really meaty.

Come visit socal, and experience it in person on the CSG car.

Can i get a test ride sometime?

ACE for the win.
