Im looking at a preddy with a 450R 42mm carb. rath racing stainless header w/ a white bros pure plaris muffler. The question i have is how much power will these add, and where in the powerband? Is this header/muffler combo. good? I ride mostly trails and mountain side trails with a few logroads.
Any input is greatly appreciated.!

 

Anyone??? Not alot of action over here.

 

Contact Rath Racing you will have to doa search for there site adn # or someone else will chime in and tell you I'm sure.

 

Im more or less looking for info on the carb. how well of a combo it is.
But thank you.
