Twin cherry bombs Vs Chambered
I am running ceramic coated (inside and out) Hedman Sorties, into a Hedman Y Pipe and then 3", no cat to the back axle. There it drops in width and is a bit shabby-
It branches into 2 and exits at a cherry bomb each side. Was done about 6 years ago (well before the 3" and headers etc.)
The pipe that goes into the cherry bombs must be 2" I reckon- 2.5" max and I guess it would drop inside the CB's too.
Am I losing power with this set-up? It sounds lovely!
I have a local firm that do custom stainless systems who showed me a tiny (as in physical size- inlet outlet of 3") chambered 1 in 2 out back box. Reckons it would sound meaner. I guess the CB's have no packing left in them after this long? I would then get them to replace the pipe at the axle from 2.5 to 3".
I don't want to lose the sound (I have other vids of me driving it in the UK on YT) I also want to get max power and I'm sure I am leaving some power on the table.
Thoughts and advice.
Old school 60s tech vs custom 2014!

Re: Twin cherry bombs Vs Chambered
doesn't look like you are. They are still outflowing what you have now (three inch pipe into, at least, two two/two and a half inch pipes. It looks like, where your muffler and intermediate pipe meet, are offset by some and might make some turbulence for the exhaust gases. You could straighten that out so it is a smoother connection and you should be golden (I think).

Unless you make every part of the system 3" you won't notice any gains. You can have some 2.5" pipe in some places, and that's going to restrict the rest of the system. I personally don't think there is a need for 2 mufflers. A good mandrel bent 3" system can outflow a dual 2" system anyways.

I doubt there would be any noticeable difference aside from exhaust tone, but you could do some basic math and get a rough guess. If you are happy with what you have, I would keep it and put money to work elsewhere where you know there will be a performance gain you are willing to pay for.

I would stick with what you have till over the axle then go to a single 3 inch into a single 3 inch inlet outlet turbo muffler and a three inch dump. Should pick up some power.
