Cat back exhaust I am getting a Cat back system put on soon at a local shop, I want to Y pipe it then have two mufflers on (im thinking borla's). My question is are headers worth it? because if its not true dual I really dont see the point but thats just me. Also if anyone has a set up like this or suggestions please let me know.

You first say that you want a Y-pipe, but then mention two mufflers. Then you say that if it's not true dual that it's not worth it.....?
There is no Y-pipe in a true dual setup.... it's either straigh, H-pipe or X-pipe.
And headers will show significant gains with a Y-pipe OR with true duals, so they are in fact worth it if your goal is to maximize performance.

I am also confused. Do u want to put mufflers on the tail pipes? Or on the Y? Dnt put them on the Y... And yes LTs make a big difference on the Fbody... Definently worth the cash... TSP has nice SS 1 7/8 heads for cheap compared to other SS headers out there.

Those mufflers look too big to fit under stock 4th gen floor pans. You might fit a couple of bullet-sized round mufflers under there, like many do with true duals and dumps at the axle, but not full-sized mufflers (unless you want totally absent ground clearance).
If you're going to go with a Y-pipe, you might as well just use a single 3" I-pipe with a bullet in-line, or small mufflers at the tail pipes, or a crossflow muffler (single in, dual out) in the stock location. If you want to use two I-pipes (like your pic) you might as well connect them to an X-pipe rather than a Y-merge towards the headers (since you're buidling a custom setup anyway); then you can either use two bullet mufflers and dumps at the axle, or continue the pipes to the rear bumper and put small muffers just before each tail pipe.

I'm confused, why do you think it's not worth it if you have to have cats? The only difference about having no cats is that the car will be louder and you get a fuel stench.

I'm also not a fan of cats at all, and would leave them off if you can. But if you absolutely need them, but can get away with moving them, then you could still build a really nice true dual system with headers and high flow cats that won't give up much power over a catless version.

they usually do visual but I dont think they care where they are as long as they are there. I mean I really want to do true dual but A local shop quoted me 1500 to do a true dual system with high flow cats and mufflers. But I have heard alot about the TSP true dual but im a little skeptical about it and can you hook that up to stock cats? or is that supposed to be ran with no cats?
