"Sleeving" a 500 exhaust with the RV8 engine

[THREEFISHORANGE]

To "sleeve" the 500 exhaust , will it cause a detrimental affect to the bhp if done incorrectly? Some people say dont just sleeve or part sleeve, cross over the pipes inside? Has anyone done this / noticed any significant performance drop, increase? Ive been advised that with a AJP style engine there is no need to cross or merge pipes treat each bank of cylinders as a seperate unit? But with a conventional v8 this is needed to create a balance, hence the tvr box perforations in the box are open to each other.
Thanks

Shouldn't need to cross the pipes...

Banks join at the Y-piece, before splitting again - therefore should be "balanced" as this is effectively a balancer pipe. No one I know of has joined the pipes inside the box, as you would be "balancing" twice...

HTH,

Didn't think about that. Its just that when different people mention cross pipes it puts a seed of doubt in your mind.
Thanks Dom
