Why the clicking noise in my exhaust?

I kind of have that problem, I can only hear it with the driver's window down, and only when starting off in first gear, sounds like it's coming from the muffler.
Just had the exact same thing, coming from the manifold. Don't know if it was a crack or a bad gasket.jdub said:Two words..."exhaust leak"
Most of the time it's the gasket...the nuts can loosen up (especially at the #6 & # 5 runners) and cause the leak. It's pretty common for the head exhaust studs to strip...the torque spec is only 29 ft/lbs for that reason. Doesn't do a lot for keeping the manifold clamped down. IMO, it's money well spent to helicoil the exhaust stud holes when doing a rebuild....you can take the torque up to 40 ft/lbs without stripping.
The newer version exhaust manifolds have a reinforcing ridge down each runner and are heavier as well...the cracking between runners that was common on the earlier version doesn't really happen anymore.
If you get a new exhaust gasket, use Toyota. They revised the gasket to a multi-layer steel...much better than the old style. In fact, the turbo gasket available now looks like the one the NA always used

You're welcome
The EGR cooler can also leak causing the same clicking sound...it's not as pronounced as a leaking exhaust manifold though.

Mine is pretty pronounced, haha. Not that it matters now :3d_frown:

WHAAAA?
Hahaha, I looked at some of the other stuff on that site, that's funny shit Kurt, LOL.
So he has an exhaust leak...but what about my sound...my studs are helicoiled, and I just schecked all of the nuts, they are tight. The sound comes from the rear of my car, like from the muffler area...hmm.
The gasket between my test pipe and cat back rattled because of a fitment issue, get under there and listen around for it.
