True Duals Set Up
umm dpends on your setup...do you want the duals to go over, under the axle, or dump before the axle...i'd imagine it depends on where you live....but anything without cats is illegal so it doesn't really matter...
umm i'd say going dumped would be illegal if anything....also will be the cheapest and the loudest in terms of interior noise...

TSP duals dumped- $420
over the axle - $500 give or take
tips - $100
this about a rough estimate. actually price will depend on shop and what brands you go with.
Well, if you want to get technical, pretty much anything other than the stock factory exhaust is illegal. Do cops enforce it? Not usually...could they? Most certainly. If you get pulled over, the word sir (or ma'am as may be the case) might end up being your best friend. My exhaust isn't very loud (Kooks headers, catted-y, Hooker), so I've never had any problems. The true duals are a comin' though...only time will tell.
I had a local exhaust shop fap up some true duals for me. I went with no X-pipe, 3 inch pipe into 12 inch bullets dumped. Sounds mean as hell. Cost me 140.00 plus the cost of the bullets. Roughly around 210.00 for the complete set up.
I plan on going cheap...
$225 for Pacesetters
$90 for Sweet Thunder Mufflers
$200 for an exhaust shop to make the X setup.
So at just over $500 you can have a nice X setup with longtubes. I wish I would have thought about this before I bought my GMMG

Not loud at all...untill you throw a big cam in there. The guys at discount tire thougth I was running open headers. I told them I had two mufflers on there and they looked under the car and said oh.

Yeah, my clearance is bad, but I'm also lowered so take that into consideration. I don't scrape nearly as much as you might think though. The TSP dual setup tucks up nicely, your clearance won't be as bad as mine. TECH Fanatic

True duals are legal (Mustangs and Vette's come w/ them stock). It becomes illegal when you do what most f-bodies do w/ true duals: use bullets and dump them before the rear axle. Bullets and dumps are illegal (but they are NHRA legal btw).

Well technically, any time you modify the exaust on a emmission controlled vehicle its illegal. In some places, like the state I live in, its illegal to not have the exaust come out the back past the gas tank buuuttttt you see dumps out there on the car
If your worried about getting a ticket, I wouldnt sweat it. In some states they can say you look tired and you can have your license taken away. The point is, if a cop wants to give you a ticket, hes going to give you one.

I have the TSP exhaust for a while now, the sound is great and the clearance is nice. What i did for the back was take a jack, and push those things up nice (with the mufflers on already). Have not had a problem yet with the cops, but i also live in Texas.
