Upgrading Exhaust

[M76Burden]

I am looking to upgrade my current stock exhaust on my 1/8 scale truggy with a JP-3 exhaust system. My question is this, on big block nitro engines (.21,.25,&.28), is the exhaust port for the manifold the same size for ALL of these engines? The JP-3 is designed for a .21 and I just want to know, will fit my .25?

Yep, the exhaust port is a universal size I do believe.

The header did not fit my losi mach .25, but after getting a new header, it worcked amazingly.

So the JP-3 header did not fit your .25? What header did you use?

I'm sorry, the losi Mach .26ss. I'm not sure which headr i got, ill check once i get home. If work will ever let me go with this hurricane stuff.

i got the jp-2 for my axial, with the stock gasket it didn't fit, but with the thinner gasket that came with the pipe it fit right, dunno if it works for your motor tho

i got the JP4 on my 8ight buggy and it bolted right on.

Also the Aftershocks/LST's require a different shaped header due to the sideways mounted engine.

Hey guys thanks for your help. I'm just picking what upgrades to get and when to get them. You have been a big help. See you at the track.
