Bolt on exaust collecotr pipe... at least to O2 sensor

[Enriquez2000]

I know there is all kinds of stuff out there for exaust.. but before I spend a ton of money buying, fabbing etc I need to make sure the motor even works.

Is there a bolt on collector pipe(one that merges after the header) with an 02 bung in it so that I can just try to fire the car up and idle?

Car does not have stock manifolds it has something aftermarket that uses bolt flanges I believe

Current manifolds if this helps

I am currently building a set of downpipes, one for a buddy of mine, and more to hopefully sell. I built my exhaust when I swapped the engine a few years ago, and now I'm revisiting the idea of building more. I 3D scanned my original exhaust and built a 3D model, so I could reproduce it. Since I'm not done yet, I haven't advertised it yet, but since you asked, I thought I'd let you know!

It does require the use of stock OBD2 manifolds.

Fully 304 stainless steel, TIG welded and back purged, all mandrel bends. 1.75" primary tubing, joined to either a 2.375" tube to be mated to a Magnaflow cat, or 2.5" single.

The goal of the design was to closely match the length of the runners from the front and rear manifolds, to be easy to install (by giving the maximum amount of clearance from the pipe to the subframe while maintain smooth flow), and allow the use of stock LCA lollipops. I have also incorporated a flex joint, and yes, one O2 bung after the merge.

As mentioned, I have been running basically this on my own car for years now, with no problems. I just need more time for a production-ready model.
