Default What's the Quieter Exhaust Setup?

Okay guys, i need some insight on what you all think is the quieter of these two exhaust setups. Both setups have the Kooks 1 3/4 headers.
1. Off road y pipe into an i with a Moroso Spiral Flow muffler over the axle and then splits into two pipes out the back.
2. Catted x pipe into true duals with magnaflow 4x9 mufflers dumped before the axles. Any input would be greatly appreciated. Thanks guys.
Brad

I'm hoping the catted duals are quieter but figured i'd get a little input from everyone before i buy. Some responses would definitely be appreciated.

Yeah true forgot about that, to the OP might just want to run tips out the back, its looks badass I think as opposed to nothing there.

For everyone's info, the mufflers are Magnaflow's 11229. They are a 3 chamber muffler, and unfortunately I haven't had a lot of luck finding any clips... however, the one that is posted on ls1sounds.com is very appealing. I bought the setup, so hopefully it's quieter than my previous one (the spiral flow setup). If not... well I guess I can try to resell it. Please keep voting and posting your comments... I appreciate the input guys.

The turndowns make a world of difference. With them pointed down and out directs the noise away from the car.

Yeah, i'm considering turning the 2 outlets down and towards each other. My friend has his oval track car setup this way and it really plays an effect on the noise level. Guys with open header setups or loud mufflers can't hear him coming up on them, and it's easier for him to know when someone else is close. Good stuff. Anyways, I can't wait to get it installed and hear it. Thanks for the vid, Mark. Be in touch.
