9886 will give you best all around esp top end

+1 on the 86. I had a few P5/pipe combos and always came back to the 86. Some also like the Jammin JP1 for a shorter track, and JP2 for longer track with the P5. I never ran the JP series, simply because I already had my Nova pipes, but they are more durable and less expensive than the Nova based pipes. If interested check Ofna.com under Jammin products. It's also been a couple of years since I changed from 1/8th buggy to nitro sedan, so there may be some new mojo on ht market

LRP 2025 , its a 3 chamber legal pipe with awesome all round power ..
