Find a local hot rod shop.
For my 97 LX450 I did a custom over the frame exhaust using the Magnaflow downpipes/single cat and the Brexhaust muffler.
I had the Magnaflow ceramic coated, the shop cut what they needed to make the muffler fit...
I know my truck was 320k plus or minus when mine failed.
I remember at the time I couldn’t figure out why the belt kept slipping off until I noticed the inwards separating from the pulley lol
