Chuck wins this one all the way, and jwwiii is somewhat correct.
The tone is not deeper at all with the X-over on the car, but it doe's have a great pulse to it.
X-over's need to be in the hot zone of the exhaust pipe to create a scavenging effect. This is about one foot past the collectors, so very little of this takes place on the SRT, far back as it is.
To elaborate on this, the x-over doe's mingle the sound by giving more reverberation to the exhaust, but most importantly it cancels out the very low frequencies generated that can not be heard by the driver, but can be heard very well beond 10 feet or more. Straight out the side is a bit muddy in sound, but overwhelming at full throttle, and I mean this to be a good thing. There are many benifits of removing this, but the untimate sound is with the x-over on the car, and deleting the sec. cats, shorter muffler. This will sound great, but no X-over also sounds good in a different way. Not for the faint hearted. The X-over also reduces drone in the car, that is very annoying on a long cruise, or when wanting to relax after a night of sporting about. This drone is difficult to cancel out. It actually takes a 6 inch muffler to cancel this out when using 3 inch pipe rather than the 2.5 the car comes with.
EPA sound levels are very strict, but it's the low freq. sounds generated that are bad. The X-over doe's cancel this out.
As far as it roasting you nearly to death, roll the window down a bit, and you won't have this so called problem. I till this day don't understand why people have to have the car sealed up when driving, as this is what makes it hot inside, regardless of A/C or not.
Chuck, is correct about aftermarket not being the answer. I've always said companies like Borla and Corsa, are somewhat govermental with the way there system sounds. I think the Mopar track system is not this way, nor are the Bullet Mufflers I try to convince people to buy from me. But the sun doe's rise and set on Borla and Corsa to hear people tell it.
