Custom made twin centre exit exhaust fits type 4 with USA triangle flanges. Virtually new, ran this on my bus for a few months but gone back to my old system as it’s a bit quieter. too heavy to post but happy for you to arrange your own courier if needed, pick up oxford or andover. £350
more pics on my thread if you're interested: Winnie the Poo (update: exhaust, again.. | Page 21 | The Late Bay Last time i looked there were no suppliers with any stock left of the "pacesetter" type 4 exhaust so that means if you have a triangle flange exhaust the only option now for an off-the-shelf system is the horrible empi that rusts even before you've finished installing it.. or get a custom system made. Or buy mine
its a bit louder than my pacesetter, but not that much. its a nice rorty sound imo and if the bus was just for me alone i'd keep it.. but .. it can sometimes be a bit uncomfortable taking the family on long drives in a noisy hot 40 year old bus, so i need to do whatever i can to make it as quiet/ comfortable as possible, hence why i've swapped back. tbh normal cruising speed its not noticable at all. around villages/ low speeds though yes its louder.
still available. £200 bargain. buy this for your self, put it under the tree with a label that says "from santa". deny all knowledge.
