What difference, sound quality-wise, does the amount of tubing before a muffler make? And how about tubing after a muffler? Reason I ask is my older cars had lots of tubing after the muffler (mostly glasspacks mounted far forward on 4- and 6-cylinder cars/trucks) and they always sounded aggressive, deep, and mean. Newer cars, with the V6 mustang in my mind right now, sound like crap with a muffler at the very end of the exhaust system. They end up sounding like VWs. My theory is lots of tubing afterwards mellows the tone out...just my theory
My maverick had a turndown, just after the muffler that ended in front of the rear axle. Cab resonance was really annoying. I added enough piping to get it past the rear bumper with no other changes. The sound (in addition to the vibration) was greatly improved. The car has some unkown brand of turbo muffler installed.
Regardless of sound, performance requires the muffler be installed as far back as reasonably possible. Exhaust gasses shrink and cool as they go back through the exhaust. For this reason, a muffler flows better the further back it is installed. This helps power and economy. Also, if the muffler has any sort of packing, the further back it is, the longer the packing will last.
Probably sounded so deep and mean because the packing blew out from being mounted so close to the engine. Glasspacks are notorious for this. Turbo mufflers can do the same thing though. Edit: You also have to account for the fact that your late model Stang example has at least one cat clogging up the works up by the engine!
Nothing like a good Easter egg hunt! Took me a while to find it Eddie. If you watched me unload my car at the Roundup last year you might be able to figure it out. I'll wait a while..
I'm sure there are no pics.. if there are, I certainly didn't take them. Scott, let's just say for reasons I will specify later, you may not want to put your mufflers right behind your collectors. The recess under the back seat is there for a reason.
I would never drive it with them there, They hang way too low in the middle of the car, and would get mangled up the first time I tried to put it on a trailer... Right now, the car is on wheel dollies, and I just pushed the mufflers on without welds or clamps, they are literally just hanging there, and if I run it too much, they may vibrate and fall off. I mounted them like that just to light it up and hear it. Today, Anna will bring home a tape recorder, and I will convert to .wav file, and post it here so everyone can get an estimate of what the super 44s sound like. But when mounting permanently, they will be just before the axle, tucked up in that recessed area. So, I had 3' extensions after my glasspacks, then cut them off to just downturns when I put in the caltracs. I never drove it like that (accelerate under pressure) but revved it in the garage, and I never really heard much difference. Did the same to my truck, had the Hemi single in, dual out Flowmaster with pipes coming out past the rear bumper, the bracket kept breaking and they would flop, so I cut them off and put on 6" downturns. The sound got deeper, more "growly". Was that due to the dumps, or because the sound is now resonating between the ground and truck bed?
