I have a 77 ford highboy with a 351m.. it is pretty quiet and im just not that kind of girl..im thinking about getting turbo mufflers and dumping them right after the rear axle to make it the loudest..help???
otherwise, if your a glasspack kinda gal, get the shortest ones you can and wait for them to blow out.
can't remember which member has them, but those moroso axial mufflers are suppose to be pretty good. those would probably have a sound half way between a glasspack and a flowmaster.
forgot to mention i had glasspacks and i didnt like them...i had flowmaster 40s on and took that off and sold gto my cousin...i like my truck loud and my buddy recommended turbo mufflers so it is between that and straight pipin..i want it to rumble, so lemme kmows!!! thanks
Welcome to FTE RedneckGirl!! So glad to hear you are NOT that kind of girl I have to say,, I had a 72 chebby,,, 400BB,,, 2 1/2" straight pipe,,, was awesome!! You could keep it halfway quiet by keepin your foot out of it,,, but when you want it to sing,, hammer down baby and you gots NOISE,,,, sweet wonderful American motor music~!! On my 77 with the 351Measly,, I have a short small Ford "resonator" that looks like a 12" glasspack,,, I have had a LOT of good comments on it also
Again, Welcome to FTE
I just finished up swapping the driver's side 460 header to a fenderwell exit header from L&L. It took a few weeks (stupid P.O. breaking bolts off in the cylinder head!) BUT HOLY HELL is it loud. I currently have one side running full exhaust (stock-ish) and the other side an open header, and it's stupidly loud. If you really want some noise, you need long-tubes and minimal mufflers. A resonator would help keep it reasonable - you could probably also run a 18-24" magnaflow straight-through turbo muffler and it would keep it loud, but not excessively so.
I can't wait to get the other side matched up (fenderwell exit) to hear how stupid it sounds without mufflers!
Then, I'll probably have to put some mufflers on it to keep it from having the neighbors call the cops on me - which would be exactly what I deserve for making them put up with my old smelly truck
I used flowmaster 10's on 2 1/2 dual pipes with 4" by 18" chrome tips on my drag truck. It would set off the car alarms down the whole block with just a blip of the throttle. Needless to say I got called in for noise a lot. I moved back out to the country after less than a month. Conversation in the cab was iffy, at the front of the truck was done at a yell, and you couldn't hear anything but truck at the back.
Going straight pipe unless smaller will actually kill power and torque and can damage the engine (no backpressure) Think over-rev!
If you want loud try L&L outboards ran into stainless Borla header mufflers and 3" stainless pipes. It's not a 351M though, it's a big block.
That's what I was thinking of doing - how loud is it? I have a pair of 2.5" mufflers that are on the truck currently - I'm probably just going to re-use those if at all possible, for the time being, and eventually want to switch over to a set of 24" magnaflows.
