When silencer repair man removed the silencer, he asked me to replace the barrel and the pipe ends till muffler!!!
as I've seen, there were no holes or damages on the barrel. But the pipe till muffler had been welded on couple of places..
so I asked him why you're suggesting me to replace these things hence they were in good condition. Then he said Sir, you cant get better fuel economy with these things (He mentioned my pipe from barrel to muffler was narrowed from some places).
Finally I asked him to not to replace anything and just do the repair. Actually he repaired it well and now the big sound from engine has gone away.
Dear friends, kindly tell me what he said was correct?, is it affecting fuel economy?
But everything is ok now and engine sounds good, still is their any chance for that?
Thanks..
