My question :

About : Tri-Y Header kit w/ Chromex Ceramic Coating & 304 stainless steel 525 cfm hi-flow metallic core converter. Comes with set of O2 sensor extensions (short & long).

Hi ! About the header, what size are the primaries, and what size is the collector ?

About the downpipe (convertor), which diameter it is ?

Any dyno chart on that ? Thanks !


Their answer :

The primary tubes are 1 5/8" into 2" secondary tubes ending in a 2 1/2" final collector. The converter in and out is 2 1/2".

We do not have dyno numbers of our own but a customer did post them on the forum. I can try to find them or you can maybe find them on the Cobalt SS Network.

Let me know if you are interested in ordering.

Thanks.

Warmest Regards,
