Custom Exhaust with Raptor headers

Postby gui67 » Thu Sep 07, 2017 6:15 am

I purchased a pair or Raptor headers for my 3.0 Legacy.
They will be here in a few days.

The car already have a Stainless steel 60mm catback.
So I will need to build a custom exhaust between the headers and the catback.

I would like to keep catalitic converters for emissions tests every 2 years and avoid mounting it on and off every 2 years.

What could you advise for catalitic converters:
one on each side after the headers, like this one for example:

Or one center cat with 2 inlets:

Or something else?
Any advice for the brand, the type of cat and other things for the new exhaust?
I plan to add a bung for an additional LC1 Lambda sensor in the future, for tuning.

Thanks for your help

I am not even sure these are Raptor as I purchased them "used". Never mounted.

If you are located in the USA it could be correct, is that where you are?

They are the first version of the header, you can keep the stock cats, nothing wrong with using them. Is that all the info you need?
