Also, in the event of hitting a pothole or something bad, you'll likely ruin a set of full lengths, which cost more to replace than a mid pipe with shorties.....i'm not trying to sway you away from LTs, just giving some tips that might not get passed on from anyone else. Another thing you don't hear much of is that LTs will actually quiet your car down a tad vs. shorties.
on the average car where LT make 2 or 3 more hp then the shorty headered car i doubt you will hear all that much louder exhaust. maybe different tone but 2 or 3 hp can't raise it any amount of db's.Redrooster said:Everything in you post was right on and gave a good point up until you said longtubes would quiet the car down. Where did you hear that? The longtubes will certainly not quiet down your car. If anything it will make it louder. HP=Noise. You make more power you move more air through the motor the louder the car is. Plain and simple. Add h/c/i to you current exhaust set up and see if the car isn't much louder. Why... because you are moving much more air/ making more power. Same thing with the longtubes. Make more power/ make more noise.

To a point, loud is loud and you won't even notice the difference...like now, i'm running dumped 1 chambers and it's loud as hell so there's not much difference, but back when i ran full exhaust it was WAY quieter than any of my friends who ran the same exhaust with the same mufflers (being in a car club with over 1k members, you get pretty big cruise in and lots of cars to compare, so again, i'm not talking out my ass).
Adding H/C/I is in no way compariable to adding an full length headers vs. shorties. That's like saying Edelbrock heads made my car louder than AFR heads. The reason LT's make the car quieter is because they equal out the exhaust pulses, which smooths out the flow of the exhaust, making for a smoother sound which equals a quieter sound. We're not talking drastic changes here, but it is there.

Redrooster said:I've been working on Mustangs for about 15 years and owned about ten. So I'm not talking out of my ass either. My current combo has longtubes on it. There was a noticable difference between the longtubes and the factory shorties. The longtubes are much louder. According to your reasoning the longtubes will be quieter because they equal out the flow. So by that an equal length shorty must be quieter than a unequal huh?
I agree the longtubes will change the tone of the exhaust. I understand that the H/C/I combo is a diffferent senario, but it has the same principal. I was trying to make a point that more power means more noise. To say they will be quieter just doesn't make sense.

They do sound great with off road H and some flows.
I just installed some BBK long tubes on a freinds car....alot easier and i like the single flange contruction alot better.....car sounds sick with a x pipe and flows
I would go with LT's if you can spare the extra dough
