OK here's my deal I'm looking to get my straight pipes as loud as I can. I have a 1 1/2 straight pipe running off a straight six 250 but here's my catch I have a turbo 350 automatic transmission so any tips? I am looking for more pop out of it not sure if cherry bombs, or glass packs would help?
I'm watching this one.....example: My 55 wagon 235 fentons, straight 2 inch into individual cherry bombs directly under drivers floor then out back to the corners and turned down at 45 degrees was defening. My 50 burb with 250 stock manifold, split 2 feet from collector and duals out to the corners and turned down at 45 (no muffs or silencers at all) has a cool 50's rumble , throaty and hot rod feel. 2 different but similar systems yield totally different results. Replicating an inliner sound with a V8 will be interesting.
If you want it to pop make sure that you have a leak at the joint between manifold and exhaust pipe. If you put a muffler on it drill a 1/8" hole just before the muffler. You transmission has nothing to do with the sound of your exhaust. That's like saying I have a fuel leak and I have a bench seat how to I fix the leak.
put a very short cherry bomb type muffler as far to the rear as possible. once some of the internal packing blows out shoul sound pretty good.
I've had loud pipes, hell for loud pipes and sweet sounding pipes and I'll take the sweet sounding over the other two any time. In your case i'd just run them straight with no mufflers or some gutted out short glass packs as volume over quality seems to be the quest.
Straight 1 1/2 inch pipes out the rear and replace the bench seat with bucket seats so the sound comes thru the floorboard better. In a week you'll want mufflers. Loud pipes save lives but drive people crazy!
You can retard your timing and run the carb too rich. Then you will get a nice poppy sound. You will also burn exhaust valves and damage your car, but it will sound poppy. On a more serious note, however the engine sounds with straight pipes is just how it sounds. If you want it to sound different, you need to modify the engine. Like increasing the compression ratio, for example. But then you are into a lot of money and time.
My chaos meter just bent the needle! You need to change your hearing aid batteries and go listen to some old cars at the next car show. No sweeter sound than a sweet six
If you want it louder than straight pipes you need a megaphone at the end of the pipe. Seriously - even a flared end will make some difference.
I am glad he didn't want to have it rapping. Oh I'm a dud with a six, I just want to meet some chix Like to cruise all day but all they wanna do is play . . . Dadut, dadut dadut dut dut. Wooooord.
when you say you want more POP out of it - are you referencing the gay interior decorator (it really pops!!!) definition, or are you really enamored with exhaust that makes popping noises (like a burned valve or an exhaust leak on a junky car? dj
had just straight pipes on my 49 Ford with a flathead 6 and twin carbs and a Red's Header... that was thing was nasty sounding.. But the neighbors and the police didn't like it LOL ! have fun, did you check any threads on this matter ..
The traditional recipe for annoying as many people as possible and collecting tickets with a six cylinder is simply to split the manifold unevenly, like 4 and 2. This adds a staccato that will cause people to hurl rocks at you as you pass their houses, and you will get to hear the greatest of all traditional Cop lines..."Excuse me for a minute, sir. I need to go back to my car for another book of tickets..."
A guy here has a nice '55 with a 6/split manifold. The humanity.....annoying as hell & he knows it. Gets on it everytime he pulls out, whadda prick.
I like to cruise out to one of those little country air strips and listen to the piper cubs take off. Maaaan that sounds good.
AS for the 'automatic transmission', I wonder if he knows how to gear it down...(shift to a lower 'range' to back 'er off, rapping the ... Pipe. Run duals, and as Bruce pointed out, splitting them up unevenly. (guys out here used to even split 'em 5-and-1!) Sounded like crap...er, Rap! (to us V8 guys) "Hey Billy! Rap out your PIPE!" (actually said to Billy Souza, before he got the manifold split on his '46 Fleetline...Santa Clara, 1955) There was NOTHING ranker than a single exhaust!
would you look at that, I went and forgot the first rule of "badass" hot rods. It will not happen again,sir! Paul
WHAT DID YOU SAY? The way I see it if you have loud pipes the wife won't ride with you, and you don't have to worry about a radio either! I would rather listen to my flathead anyway.
There is nothing more fun than quietly motoring past a loud 15 second car. Here is a trick to running an automajic, shift it manually rev it up tight and lift between shifts. Hey mike, Remember when rapping meant two people talking?
do folks complain about loud harley's like they complain about rapping pipes on an old car? i enjoyed my '51 that would sound good while shifting, once it hit 3rd, i wouldn't even hear anything.
