Most of us tend to drive the cars and evaporate the moisture from the mufflers more so then what people used to do when these cars were new and used for transportation. Okay, so I do to show off the mufflers' sound but I have no worries about them sticking as know what I did to them internally. Plus, none of us fire up the car and listen and then shut them off. With the new fuels we have, the issue is not like it used to be in 1970. 409 builds up a surface condition of light discoloration/oxidation that then tends to stay put. Both of these stainless steels are resistant to rusting all the way away. The dissimilar materials keeps the sticking from occurring indeed, it did in 1969-1971 when the parts were all 409 st.
I (and Waldron's do I believe) use a 304 st.
The set below in the photo is on a 1969 Cobra Jet 428 Torino.Īnd that is a great question 62MaxWagon. Mine are louder than the VOE GTO versions. The second is my car with the stocker VOE mufflers. The first video is a true 1970 400 VOE GTO. The sound levels depend upon engine of course but I saw around 9 to 10 dBa difference in many rpm levels on mine. For Bs, you could use the 19" or 20" case size. I did a lot of tricks inside of mine to bump the air flow up and the ones that Waldron sells are darn near as good, air-flow wise.įor our A- cars, the 18" cases will fit fine although you need to drop the nose down a tad to clear the 4" actuator needed. For sure, they are not drag racing mufflers, they were not meant to be. They are expensive but offer a person the way to have the best of both worlds. They flow like stockers when closed and even though this is not anything to brag about, they pass as much air when open as the equivalent sized Flowmaster. They have zero resonation when closed and they roar when open. Re: Really quiet muffler that flows 1/2 decent?įuryFan, I made the set on my 69 Cuda and they are quieter than stock when closed and as loud as Flowmasters when open. I would not consider anything over 2.5 as quiet, it even in the 2.5 size you have to pic the muffs carefully if the motor is stout and you want quiet.Īnd not to go off-topic but once again I am reminded of my question Why no 2.75" pipes/muffs? Seems like such an ideal size. Given the same set up (brands/configuration) a change from 2.25 to 2.5 to 3.0 will make a BIG difference. He claims I won't believe my ears and is insisting just as a tip to not waste money on larger exhaust for purposes of sound alone. He's bringing me before & after video to watch of his Mustang when it had 2.5" and now with 3". I just got into a discussion with a coworker (Ford racer) on this exact topic and he swears up & down that in regards to sound the size of the exhaust system has virtually zero effect on volume, it only effects the tone. check his other videos, he has done alot of research on diffrent mufflers.ģ" will be a lot louder than a 2.5, or 2.25 for that matter, system. The above link is 3" exhaust with 14" Dynomax ultraflo muffler.
