8.1L Muffler Recommendations

After 18 years the muffler on the old Chevy 8.1L has a hole in it. Sounds like an old grain truck going down the road.

It's a dual-in, dual-out 3" pipes all the way around. The only "OEM" style replacements I can find are dual-in, single-out.

I'm also hoping I can just use those fancy band clamps to install the new muffler. Cut the old one out, clamp the new one in.
  • Car Id has them , if that doesn’t work for you , google is your friend
  • Had a Magnaflow dual in, dual out on my 7.4L for years and years

    Finally rusted out and became very loud like your description of yours

    Now have a Magnaflow SS dual in, single out. 2 inch single with a SS tip

    LIke it better than the dual in, dual out...as this one is quieter, but not OEM level
