Andydodge Posted September 28, 2008 Report Posted September 28, 2008 Gidday from Oz......went to a small, local swap meet today and a guy had a pair of new 30" Smithy's Mufflers for sale.........they kept calling me.......buy me.........buy me........buy me..........so i did...........now does anyone have any idea what these sound like?........, I eventually want to run a split exhaust/home brewed headers on the P11, with edgy head, twin carbs etc,ie, but essentially 3 cylinders running into a dual system front to back........my question.......are 30" long mufflers TOO long.........I don't mind a bit of noise, basically I want a hot rod sound, not a stocker, I like to piss the restorers off so noise is good............lol..........any comments?.......andyd Quote
mackster Posted September 28, 2008 Report Posted September 28, 2008 Hi Andy, I had dual Smitty's on a inline six Chevy engine 235...It was a nice rap pap pap when decelerating and a deep tone when in cruising speeds. I enjoy people looking around because the sound was loud. HOWEVER the LA cops do not enjoy it as much as I did and made me get rid of them. I then ran straight ten inch pipes. I thought they were loud but not too annoying. my wife even said it sounded great. so what I'm saying is try them, if you don't like them you can always trade them for something different.... Quote
martybose Posted September 28, 2008 Report Posted September 28, 2008 I'm running pretty much the exhaust system you mentioned; I've got 3 into 1 cast iron headers, 2 inch pipes with no crossover, and 30 inch glasspacks. Has a nice rumble, and isn't too loud to me! Marty Quote
BobT-47P15 Posted September 28, 2008 Report Posted September 28, 2008 The longer mufflers give a more mellow tone. The shorter ones get pretty loud and more harsh tone. At least thats what Ive read. Quote

Suddensix Posted September 29, 2008 Report Posted September 29, 2008 Hi Andy, I have 30" Smithy's on my p18. I'm running the set up you hope to and the mufflers sound great. A nice mellow tone a bit on the loud side but not annoyingly so. Cheers Gary in Toronto Quote
Andydodge Posted September 29, 2008 Author Report Posted September 29, 2008 Gary, thats great, loud is good..........lol.........thanks, andyd Quote
hucks 50 Posted September 29, 2008 Report Posted September 29, 2008 we didnt get to see a pic of grampa's car looked like a fun drive ,cant wait to get my 50 on the road Quote
blueskies Posted September 29, 2008 Report Posted September 29, 2008 Andy- Can't remember off the top what length my smithys are, More here... I have a cross-over just ahead of the mufflers, so it mellows the tone quite a bit. Pete Quote

My car sounds much like blueskies does in his clip. Cheers Gary Quote
Andydodge Posted September 29, 2008 Author Report Posted September 29, 2008 Yep, thats just what I want.........VARROOM......lol.........only hiccup I'm gunna have is the exhaust manifold as I've mentioned the P11 steering box lives where a front Fenton header would sit, so I've got a new new set of extractors/headers of a 302 Ford that have nice mandrel bends and only 1&3/8th primary pipes and am gunna chop these up and make a set of headers that hopefully will fit.......many thanks for the info and sound......andyd Quote
