I'm of the same thinking.lc-gtr-1969 wrote: ↑Sat Dec 11, 2021 3:36 pm
I do not think these AR Chambers are quite the same as termination boxes, both may help minimise reversion for obvious reasons, but as you suggest, I am not sure the AR chambers have the volume or dramatic change in area that a termination box will have to induce the engine thinking it has open headers.
If I could fit a termination box I would run one but room is quite tight under there...
As for packaging, try fitting that under a 3rd gen f-body. And a lowered one at that.
That said, I can forgo the chambers and easily run an open header for the full effect. Which is something I hope to experiment with this test and tune season. That would be via cutouts at the appropriate distance from the collector.
