Exhuast problems

[redneckgolfer72]

I just put a new thrush welded on my 2002 4runner yesterday. It sounded great, but today i started hearing a ticking when i accelerate.. Its very annoying and i looked online and i some say spark plugs and some say exhaust manifolds... so if yall don't mind helping me out!
thanks

More then likely a leak. Probably have a pinhole in the weld. Inspect it very closely.
