Bus Has Holes in Muffler!

This video was shot at the Illinois Railway Museum on Saturday, September 28, 2019. The bus is 1979 GMC RTS #421 from Janesville, WI. Its powertrain is a Detroit Diesel 6v71 engine coupled to an Allison V730 automatic transmission. This bus could be heard from almost everywhere on the museum grounds.

Hope they kept the holes! Sounds like the 2 strokes used by the GMC new look fish bowls! Ahh the child hood memories that come rushing back!

Putting the scream into "Screamin' Jimmy".

Oh hell yeah that's what I'm talkin about RTS 6v71 Detroit diesel power 🤗🤗🤗🤗💪🏽💪🏽💪🏽💪🏽

I love that sound. I really miss those buses

[@christopheryanoski6899]

Back in the 90's as a kid that how you knew the bus was coming blocks away.

Grew up riding RTS with that exact Sound at Kalamazoo/ Battle Creek, Michigan and Gary, Indiana GPTC

[@ETBX1]

The initial acceleration sound is so bassy, it sounds like it's going to be an 8V71, but once the rpm's are up as it speeds away, it's the familiar 6 sound! For some reason I like when 6's sound as heavy as 8's.

Throaty Detroits? Oh hell no!! X_____X I can't

I used to hear these as 1981 and 1983 models in NYC a lot. Only NYCTA and MaBSTOA had these. The last hurrah was in 2001....

[@keontreadwell4063]

I wish the NYC/MABSTOA 81s and 83s RTS had 6v92 engines in them

[@knightclassic1]

I hear Queens and Staten Island Depots hated those 1981s because they were so Slow going up the Hill (Like FIshbowls) , Some had No-Power Steering

[@Ballsarama]

I used to drive one like this at NIU in DeKalb, IL. Loved them.

[@lesliemiros6743]

Most of the ones we had in Houston, Texas sound like that too

[@lesliemiros6743]

St Bernard Parish had two RTS buses had that same motor sound

[@Crosley-1520]

Sounds better like that!

[@schnuurtchke]

Sounds good man!

[@jorgefigueroa4437]

1980 and 1983 San Juan AMA GMC RTS units, the best the first order consist of 126 units replacing 1962 and 1968 GMC New Looks, and part of the 1970 Flxible New Looks, the remaining renumbered to 723XX and 724XX units

[@caseystrange]

Janesville used those buses back in the 90s and early 2000s. They use new ones now. Different colors and layout.

[@WARD5KUSTOMZ]

Janesville, WI had a GM assembly plant!

[@isaacsims6203]

To me the best sound on tbe rts was the 6v71 with the allsan 731R

[@devonsatchell]
