When you talk those kinda of mufflers the top 3 are
CherryBomb

&
CherryBomb
now someone may bring up Thrush and I would agree but guess who owns them now and uses their tech in the straight shot glass packs, why Thrushes are red now
[though if you found some NOS blue [has to be blue] Thrushes id by em if your rich n got money to burn.]
Though those type sound the best when installed right off the headers or Y pipe and then run a full length tail pipe off it.
Think of a musical horn, the part that blows is the engine, the glass pack is the mouth piece, the tail pipe is the horn.
They sound like crap when they just dump, or are way in the back to far from the motor.
no sounds clips but Ive had them on many different types n sizes of motors and that always turns heads for the best.
