Default Ypipe to bullet then dumped

I've searched and found a few threads on this subject. I wanted to know what the consensus was on this subject. Right now the car is H/C w/ long tubes, Kooks ORY, magnaflow catback. The car is real quiet at idle, but it screams at WOT.

Does anyone have experience cruising with the dumped bullet after the ypipe? Does it compare to a true dual setup dumped before the axle? I had that on the car when I bought it. I was thinking of switching for the sound, flow, and weight savings. Thoughts??? BTW, the car is a weekend warrior.

Thanks,
Andy

UPDATE:

Well I just picked the car up. I waited to get a piece of pipe welded to have the muffler sit right at the rear axle.

The car is definitely louder. Cold start up made me smile. Cam lope is a lot more noticeable. It has a nice deep, "muscle car" tone to it now. The rest of my exhaust is QTP long tube headers and a Kook's 3" ORY. There is a slight rasp around 2,500 rpms but it goes away quickly. You just learn to get through that rpm range quick. I haven't really gotten on the car too much yet but above 3k rpms the car really wakes up and makes noise. Cruising around town under 3k rpms it sounds like a normal muscle car with exhaust. You can't even see the muffler from the side of the car either. I consider it money well spent.

Now for the pics:













Added a video!

Exhaust is a lot deeper in person. A little point and shoot camera doesn't have the best microphone in the world. Haha.

I had one with a bullet dumped after y. It's loud, but I didn't think it was raspy.

I was thinking a high flow cat followed by a bullet may be the answer. I'm talking about the cats that are a straight thru design much like the bullet.

Well the one chamber flow is square and might look out of place under there. At least with the bullet and flow thru cat, everything is round

i tried this on my 408 and put the 4" catback back on the car.
no rasp. sounded great, but got old after a couple days of driving.
scares small children, people stare at you. its like rolling around with the cutout open. the single bullet does nothing for the loudness, it just takes the "ring" out of your ear a bit.
i like stuff super quiet, so it may be just me....

I had LT's and a offroad y-pipe to a DNA muffler on my car. Loved the way it sounded. No rasp at all.

I had the Kooks ORY with a moroso spiral flow muffler on the end with a dump, imo it really wasnt overly loud. There wasnt a lot of drone at cruising speeds. I recently bought another spiral flow and dumped them at the headers, much louder and much more drone on the highway.

How do the moroso spiral flows compare to the dynomax bullets?

That clip sounded good. Didn't appear to have any drone at cruise....then screamed at WOT. I didn't hear much rasp either.

I had a spiral flow dumped. It sounded amazing. It was just to loud for me. It wasn't raspy and had little drone.

I've got a video - http://www.youtube.com/watch?v=RgB9k...eature=channel

3" y to single 4" bullet. no rasp, and it wasnt insane in the car, but it sure is loud outside.
i actually have more of a resonance inside the car with the full catback on, but it keeps it decent for cruising around.
