I'm about to buy the new Plus-4 BTT but want to know if it needs the new exhaust gaskets or can I use the old style gaskets also?

You can use the old style gasket if you are in a pinch, but the new ones are alot better and last much longer.

21000/2 should be available but ..............

yes the old ones still work

What would a 9901 do for a P5XLT running 25% and a 6mm restrictor in buggy? How would the engine characteristics change from a 086?

heres what i would recommend on a p5xlt in buggy with a 9901ss

p5xlt shimmed to .65mm , 7mm restrictor , 9901/41021

from 086hs to 9901ss equals much better runtime smoother power transition much better runtimes and a touc hotter temps as it is a more rstrictive pipe

Edited , brainfart

So then it would seem like I am more or less where I want to be with the 086 on my P5XLT? The 9901 wont do a whole lot for me it looks like.

Thank you, ordered the engine. Hope I don't have to wait to long.

What exactly are you looking for?

Ideally I would like a smooth power band with a good mix of bottom and top and good runtime.
