I mis-interpretted your post to mean that any true duals without a h or x would sound bad. I agree with you the dual LM1 setup is a bad idea.
My mufflers are in the same place as the TSP duals puts them on a fbody, I've installed them on 2 different friends' cars. Muffler type of course is different. My point was just that duals do not need the crossover to sound good, which as it turns out isn't what you meant.
TSP duals with the Sweet Thunders, 1 chamber Flowmasters, and Dynomax bullets all sound excellent.

The only way a TD LM would sound ok is with an X at least and switch out the resonators for Borla, Magnaflow, or some other mufflers.

Yes I'm running high flow cats and an X pipe, and why do you guys say my setup is a bad idea??? It sounds great to me and many others that have heard my car in person........

For duals, either buy one of the premade systems, or buy a junction/pipe/and muffler of your choice and have it fabricated.
Hacking up stock style F-body exhasut for an LMI resonator (that SLP used to sell, and may still, as a stand alone item) is really a waste of time and resources.

At that point you have bought two factory LM systems, hacked them apart, and replaced the resonators. It really isn't even an LM based dual system anymore. Might as well by some stanless pipe, x-juntion, some mufflers, and get to welding.

I agree, but I have seen it done a few times both with and without replacing the mufflers. The only problem with pre made systems are most don't run all the way back, and the ones that do are very pricey. If you already have a LM another one can be found used for cheap, so if you wanted to run your set up out the back you have all the pipe and it will keep the labor cost down at a muffler shop.

That may have been one of his ideas, which is shy I strongly recommended against it, especially without a crossover pipe of some kind. In many other states it could be fine but in Kali it's just asking for trouble.

Yea I've decided to ditch the whole LM1 thing all together, I'm just gonna get the headers and Y-pipe on there with my dual/dual and see how it sounds. I think I'll just end up getting new tips for the dual/dual to change the look and once the cam goes in it should sound pretty good. The FLP Y-pipe has cats but it also is easy to take them out and put in the straight tubes in place of the cats so I can hear and try both but in Cali I'll be keeping the cats on 99% of the time.

You're going to want some good mufflers, if you don't run cats. Id at least remove the LM1 resonator and put a Magnaflow #12867 in it's place. Iv'e got a Borla in the I-pipe and a magnaflow oval out back and it's still loud, but it just a deep rumble that's not irritating at all.
IMO, you might want to try it out first with the SLP Dual/Dual (with the silencer ring removed) since it will be louder with the cam, headers, and no-cats

Truthfully, loud exhaust is COP bait, or in SMOG **** LAND, California Hater Patrol bait, same thing as window tint. Some CHP dont care, and then there are the ones that will do 40mph through a parking lot just to write you a window tint ticket. Trust me, ask how i know. I love how they regulate what i can put on my car, but dont give a **** if some one pops out five children that they cant provide for!!! BTW smart choice on exhaust, your CHP bait % just went down... hahaha
