I was just wondering if holes in a muffler would affect the power in a 85 300TD wagon.

#1. Recently my car seems to have been less powerful and I found out there is a 3rd hole in the muffler after patching

#2. The loudness of the 3rd hole discovered seems to be coincidentally timed with the power loss.

Could there be any relation?

I didn't think so, but hey, I'm still learning about these machines..

Thanks
