has anyone ever heard of a CVEC tuned pipe, i fount a used one for $5.00.....it has 2 exit exhaust ports instead of just 1 exit port i guess i would call it...he says its made for engines in the .21-.28 range and ddint know if this is a good pipe..he said its a 3 chamber ???

I have 3 cvecs and the only thing i dont liek about them is high maintanence. You have to clean the internals every time you come in from running the rc. Other than that you can tune just about any engine to get better fuel consumption or better mph. They have been discontinued from production now for about 2 years and you can still find a few floating on ebay for cheap. These 2 I brought off ebay 1/2 a year ago brand new and never got to use them.

ROAR and rc pro series wont let you run those pipes, it has to have one stinger instead of 2. Local club type races should let you run those or if your just bashing it will do. I like the werks 2013 pipe, great exhaust for any 21-28 engine.
