1. you need to know that the TSP duals that everyone is talkign about are dumped, they do not go all the way out the rear of the car.
2. don't listen to black mamba, he's being an idiot.
Black mamba, what the heck do you mean don't bring bassani into this? IT showed a HUGE gain over a catback system and you don't like being proven wrong? Not to mention the bassani system is only 2.5 in ch duals rather than 3" and it STILL made a big gain over the catback system. And how are the best sounding "true dual" setups done through a catback? that doesn't make any sense at all.
3. catbacks generally have rasp that duals generally don't, period.
I got my custom 2.5" over the axle duals done for $300 including the price of the 1 chamber flows.

Also, when I switched to the TSP duals, I gained a bunch of low end and mid range, with a little top end. I think because of the x pipe. My car accelerates much better from lights now

Yeah, i love my dual set-up. I had flowmaster 80 series cat back on it before. It sounded pretty good, but the duals sound sick (in my opinion at least). I have come aross a few people that don't like the sound. But, who cares, get what you want. The power gains over the flowmaster are rediculous. So much more power through the entire rpm range.

I'm not a big fan of dumbs, it is crazy loud in the car and has a bit of a drone compared to the snappy sound if you get it all the way back. The TSP dumps look like good quality exhaust for what they are though. I'd prolly get them for a weekend/track car if I couldn't find a shop to do it out the back for cheaper.

i LOOOOOOOVVVVVVVVE my tsp duals and get tons of compliments. It's also a good was to scare the dick head that just cut you off by dopping down 2 gears and punching it.

If you just want a car that's louder than hell, has absolutely no tone, and don't care about looks, then get them. Otherwise, get a catback, it will sound better, and hey, you'll only lose about 2-3 peak WHP...
You can also consider a cutout. They sound about the same...

I have the Sweet Thunder and it sounds amazing at idle, part throttle, when cruising, when punching it, etc. It also isn't as loud as the straight-thru bullets (at least until WOT) which can give some people headaches on long trips. I've had my car at wide open throttle next to another LS1-powered 4th Gen. Z28 with the Texas Speed true dual system with bullet mufflers. You could not tell the difference at wide open throttle, however at part throttle and idle it was almost too loud with the bullets for my tastes.
The chambered Sweet Thunder mufflers as well as the Moroso Spiral Flows may restrict some flow, but in the end I think it is a great trade-off of sound vs. power for someone who drives their car on the street. I only drive mine about 4000 miles per year and haven't regretted my decision of exhaust yet. I'm sure I will enjoy it even more once I have a camshaft swap done this coming spring.
My full bolt-on car makes consistently 8-10 RWHP more than similar bolt-on cars that were on the same local dyno. That is with the Sweet Thunder chambered mufflers. I'm sure power output would be a little bit more with the straight-thru bullet mufflers. Once I get into more serious, the gains over a traditional y-pipe and catback set-up will be more.
Please at least know what you are talking about before badmouthing a product that is generally accepted in the LS1 community to be one of the most affordable and best sounding ways to put a true dual system on one's car that will bolt right up.

I got the TSP Rumblers w/ spiral flows and i love it. w/ my pacesetter LTs and this i think the total came out to 900 and i was able to get it all in with the help of my dad over the weekend. The TDs fit nicely, it just takes some time making sure everythings angled properly and tucked as high as it will go. Some people say its too loud in the cab but i can drive for hours and not have it bother me. Everyone who drives behind my says it smells like raw fuel though (no cats) but i have never noticed it. Either way i'm perfectly happy with it and am not changin it.

I've had a few custom TD setups done. There is a few options from what I have tried and what I thought of it:
1. Dumps before the axle - easiest and cheapest to find a shop to do and works for almost any application but will net you some added drone and exhaust noise inside the car
2. Out the back and under the axle - pretty easy setup and doesn't have the added sound inside the car, sounds great outside the car to not have the exhaust spitting at the ground, horrible if you work on your car a lot, you will get sick of removing your exhaust everytime you put your car on a lift (your rear end will drop down on the exhaust, let it sit on the exhaust if you want a cracked header, it happened to me once)
3. Out the back and over the axle - the best choice in my opinion, gives the best sound in and out of the car and looks better, hard to do on lowered cars but F-bodies are for drag racing not to look cool at pimp my ride conventions, easiest route is both pipes going over the passenger side over the axle and splitting back out after, I have seen some that were over both sides though, never had a car like that yet

Like I said above, I gained alot of low end and mid range with some upper range power with my TSP duals. The car accelerates much more fiercly now. My previous setup up was about the best flowing y pipe setup you can get, I had an ORY and loudmouth1. pretty much straight through. But the duals accelerate much better. No dyno numbers though.
