Exhaust Flange/ Down Pipe Problems

[Bosshawg600]

So I had another member be kind enough to swap my 3.0 S400 for a 2.6 S400 and I got it all mounted up...but its got a flange on it that doesnt fit my current down pipe and I cant find anything to make it fit.

Old Turbo flange, typical 4" V-Band

The new flange Looks like 4.5" and its pretty thick....its also a V-Band

Does any one make an adaptor? I realy dont want to buy another down pipe or even have to change the entire exhaust to 5".

Looks like a B1 style or marmon flange, measures somewhere around 4 9/16". Might also be 4" ID versus the top housing which is 4" OD. Doubt you can turn it down to fit. Looks like new downpipe or source the same AR housing only with an hx40 flange.

I always thought you could get the marmons milled down to an HX40.

It does look like there is enough material to get it milled down, but i think an adaptors is the cheapest and easiest route.

Maybe try this?
