Land & Sea Exhaust Adapter and Tuner vs Mer 260 Adapter and Tuner?

[jhelmly]

Engine setup with Land and Sea unit, runs fine, building up a Mer 260 plate and turner just to have (dry stacked etc.). Just wondering if I would see enough difference to take the time to change over. Both are one peice plates. Land & Sea turner is half the length of Mer 260. Also is there a gasket between the plate and turner on Mer or just a machined surface. Do not see a gasket in parts view.
Thanks

I have several L&S adapters, they work, but the Merc adapters have stronger low and mid pull from the tuners compared to what the L&S plates offer. There is very little difference on top end between them
