Muffler shops on North Shore

Can anyone recommend me an exhaust/muffler garage on the shore?
My exhaust is very close to the drive shaft which now and then rubs against it causing a grinding noise.

Need to take it in to be checked out.
I was recommended Al's mufflers - but apparently there are better outfits out there

any advice is appreciated
cheers

was gonna say als
they do good work and reasonably priced.
