Hey everybody, I hear so much about magnaflow exhaust. I'd like to make my 93 F150 with an Inline 6 300 have a nice deep tone but nothing I have tried has given me the results I want. Are magnaflow mufflers truly the best with that great sound?? Thanks

 

It's the best match for F-150's that I've used and many here feel the same.

magnaflow is the freest flowing muffler have you tried glass pack if not give magnaflow a try. I have a 302 and have shorty headers and all custom truedual set up with glass packs and no cat and it isnt really loud

 

It is really hard to make the 300 sound bigger than it is. In my 83 Bronco with the 300 with broken exhaust at the y pipe it did not get loud. So good luck.

 

What length glass packs are you running? I'm thinking of a similar setup for my '83 F-100 302. Would like it to have the V-8 rumble, but not be obnoxious.

 

Even the 302 doesnt get the "V8 rumble" you are thinking of. The only way to get a good rumble with these engines it to add full length headers like I did. That may be a little too much work for what some of you guys want. I would upgrade to a high flow cat and a 3 chamber muffler. There are some resonator exhaust tips for trucks out there that sound ok. Alot of people remove the cat to make it louder but I think it sounds too echo-y for my liking without one. What I did (that took alot of time, not too much money, and was a major pain in the ***, but worth it) was I put on full length headers to 2 1/4" dual pipes and ran them into dual cats with a 3 inch outlet and ran 3 inch dual pipe and mufflers with turn downs under the bed. Rumble doesnt begin to describe it, more like race car sounding especially when accelorating. Ill post pics on my gallery sometime soon.

 

hey.. i have a 95 f150 with a 300... i cut the exhaust off after the cat and ran a 3 inch pipe to right infront of the tire.. it was load.. to load and didnt sound that bad for the firtst day or 2. then i got a head ache.. if u want load i would do this.. i then put a flowmaster i got for free on it and its just how i like it. u can hear it from the out side but pretty quite inside. hope this helps..

 

in response to bluthndr93s question, i dont think expensive mufflers are worth it on the 300. its a great engine but it sounds weird, if you can get the magnaflow cheap enough then give it a try.

on my old 300 i ran a straight pipe, 2.5 inch off the manifold and bent out infront of the right rear tire. it sounds mean when its revved in neutral, it sounds mean under wide open throttle, and it sounds like a tractor when puttering down the street. i tried many differnt exhaust setups behind my 300. most that i tried yeilded a mean sound when its revved, but then it would sound like a fartcanned honda when going down the road. usally what sounds good behind a 351 or 302 will sound wierd behind a 300. its a differnt engine and it needs a differnt exhaust to sound good.

in response to mrl390, my 302 has all the v8 rumble and then some. true 2.25 inch duals off the manifolds, no cats and 31 inch glasspacks. it'll rattle the kitchen window when its idling outside. it has a deep rumble under light throttle, and it'll rap and cackle off the line under full throttle. i have heard various 302s in trucks and mustangs that have the loud annoying echoy sound. i know ford changed the firing order on the 302 in 94-95ish to the HO 351 firing order, maybe that affected the sound in a better way.

although glasspacks didnt sound great on my 300, i love them on my v8s. on my 351, 86 f150, i ran long tube headers 2.25 inch duals, no cats, a set of 31 inch thrush glasspacks and i bent both pipes out infront of the tire. this is by far the most wicked sounding truck i have.

parked side by side my carbed 351 is twice as loud at idle, but my efi 302 sounds deeper even with the stock manifolds.

 

I swear the best 302 sound you will ever hear is removing the cat, and putting on a dynomax crossflow muffler. Its a dual in dual out muffler with an x pipe all in one. I put it on my 85 with a 302 EFI and long tube headers, and man, its not raspy and annoying, its like the baddest thing i've ever heard.

 

go look for a 18" stainless steel tip its going to be 2 1/2" X 18" ....it looks better if you split them into duals but the tips is what makes a diffrence...I can careless of what other people say on this subject because I have done this with 2 many cars.....remove or gut cats--run 2 1/2" pipe ----any turbo muffler (it doesnt matter) then the tips...those tips give you the sound you are looking for ...if you vent them out at 45 degree angles behind the tires instead of straight back the sound diffrence is amazing...alot of people spend so much money on an exhaust "Flowmaster,Borla,Dynotech" and they could get by with so much less money and get the sound they are looking for...did you know they make a 3 foot glasspack that doesnt pop when you let off the gas....We have trucks and big tips look good on our vehicles....now if we had an old muscle car like a GTO or Chevelle then the 3" exhaust comes into play....or if you had a Ricer...you would goto www.procarparts.com and get some "racing otto mufflers"... everyone talks about free flow exhaust....well pick up your mufflers and look through them ....can you see the other side...hmm NO...well those OTTO mufflers you pick them up and yes you can see straight through them...they are built like a true silencer...drawback....if you have a High output motor that equals LOUD....like sound police loud

 

I had a single in dual out 40 series put in my truck and then I flanged in about the smallest cat that would get me by. The truck has a nice deep tone with a little popping when you get the gas. But If I really want to wake people up four bolts and you can here the truck two blocks away! I do think the truck runs better with the cat in though.

 

i think they are 18s
