Ran straight pipes on the 37 V8 for years but had them straight out the back...finally had enough and put on a set of 22" Smitty's and it purrs like a kitten.
....I've used Smitty's on other things and have found it takes a while for them to "burn out" to finally reach the sound I like.
....I put a cheap Thrush on the 50 coupe so I could here the 261 run and it ain't half bad but don't have the last section of pipe on it yet.
If you like it.....run it!!
