his exact words were "retorque to specs" and i couldnt find any specs so i just tightened the bolts. theres a brace on the lower en of the header that i was unable to put back on because the stock bolt didnt fit the megan header. the wonders of aftermarket parts. i think the lack of the brace is whats making it make the vibrating noise. maybe i dunno

This may or not be the problem in your case, as I dont know where you got yours from. The vibration is coming from the heat shield "shell" just above and around the collector area... take your finger and "flick" on edge of the shield, you will make the noise, and see how very flimsy it is. |

Personally, after seeing the thread about the 'gains' from this header I opted out of it, but If I recall someone said megan sends the wrong size bolts, and they had to get some other size.

Alotof people take it off, basically its just there to say, DONT TOUCH ME IM HOT, to prevent people who dont know how hot the exhaust gets from touching it.

The heat shield on the stock header will not, and is not, designed to fit the Megan Header. |

my Megan header did not come with the correct bolts. Fortunately, my friend at the shop had the correct size.

Those with hardware issues.. were did you order yours from?
I know of knowone from the original Megan GB way back when, reporting any issues. Wondering what's going on over at Megan, or whoever builds these for them. Sucks. |

It would be unusual for it to misfire, and yes, it would throw a CEL if it did it. Toyota's intelligent tester tool would be able to tell you exactly if that is the problem, so if in doubt, go to your toyota service center and ask them to check it out. My guess is, because of the low idle of the engine, it could look like it's shaking, once it's warmed up. You could always invest in a torque damper, that will keep things in place
