MOPED ARMY

the inside of your engine? you mean the inside of the pipe? and by the baffle breaking off do you mean the header?

if there is a whole bunch of extra weld in there yeah it could mess up the flow. he should have ground that out, but thats also assuming he understands how they work. dont be so quick to jump on the guy that helped you. remember, the pipe was broken before you brought it to him. easy enough to fix if you are polite with the guy im sure he would do it for free.

easy to do yourself too, just grind that shit out.

Solution: file / grind down the weld beads on the inside. If you can see them, you can remove them. You might need a long tool (possibly a dremel with extender bit, or a flex-shaft tool). Easy work, just time consuming.

And make sure to clean all the metal shavings out when you're done!

I went and bought a dremel tonight and got most of it out, but I ruined my dremel bits too quickly to do a satisfactory job. Tommorow I'll get more bits and finish that. I think I'll try dremelling out my intake manifold too. I definitely recommend anyone that doesn't have one of these to get one and put it to good use.
