I was wondering if a performance pipe would hurt a atv engine, i heard yes and no form many different people

 

as long as u rejet it wont...

 

No it wont... It gets more air to the engine and out faster making it better. But you must have your fuel and air ratio perfect to really be perfect.. But yes it not only does not hurt it but it givees it.. UMM performace haha

 

i heard from a mechanic that it wears the pistoon and rings out faster then normal and causes other things to break

 

that could be because of the way it is used after it's modded. all youre doing is making the engine more efficient, more like it was INTENDED. all the quiet mufflers and stuff are for govt regs and sales, not for performance. most rigs run way better without the factory exhaust, see but the factory is required to meet certain specs for noise etc. when you buy it, it becomes your responsibility....so...man there are a lot of pipes on the market!
