What is the torque specs for the head pipe on a 2006 trx450er ? I got a new after market one need to tight it up just do not want to go over board or not tight enough and fall off.

Mine never hold no matter how tight I put them. I actually double nut both sides on mine now.

In the honda manual, at least in the exhaust removal/installation section it mentions several tq specs, but not those. I just put them back on as tight as I took them off.

keep in mind, after you install them, run the quad for a few minutes. The nuts will loosen as the heat will stretch the studs some. Then tighten then again, they should hold then.
