For all those who upgraded their engine for the 1/10 scale buggy,what differences did you see?Do I have to break the fuel pipes to get them off and get new ones in order to install the engine?

What motor are you upgrading to, and no the mufflers are on with plastic ties just cut the ties and pull the muffler off, you may have to order a new peace that goes from the muffler and the motor.

Maybe some OS engine.I was not talking about the muffler.I was talking about the tube that gets fuel from the tank to the engine.

They just pull off.

i got a torque pipe and a new exhaust manifold and my acceleration got 100 times better

what kind of manifold did you get and where did you get it?

This may be something like he's talking about.

How can you tell if an engine will upgrade your car?I now have the engine that comes with the buggy.

thats a good one but you can get one from redcat for 1/2 the price, i changed all my manifolds on my redcat 1/10ths to this one: http://www.redcatracing.com/itemdeta...?partno=02031a
