If you were to order new longtubes, would you order them off-road or with high-flow cats.... cost difference being an extra $150 for cats. Or would you prefer offroad with resonators?

Depends what sound I was after and what vehicle it's going in. A C5, I'd go with a catted setup because it sounds smoother; an f-body, I'd go no cats to have a nastier sound.

The headers themselves don't have the cats, though, so the question is also whether you'll be running a y-pipe or true duals.

I am talking about a custom set-up for an f-body to be specific. I know what I would do, just curious what you guys would do

For an f-body with a Y set-up

Catted y, Flowmaster merge, Mufflex 4" setup.

i've heard about people getting these ORY with better mergers....which one would be a good one to get? or are you talking custom?

Everyone seems to use the Flowmaster Merge.

Depending on what setup for the exhaust im using. As for now, ill stick with no cats on a y pipe setup.

In my opinion, it depends on what catback you plan to run.

Something with a full size muffler like Magnaflow or Hooker, you can get away with not having cats and still be without the majority of the rasp these LSx motors produce.

But if you're running a catback with a resonator (Loudmouth Systems) or chambered exhaust (GMMG), I believe cats are the way to go to keep these setups from becoming overpowering.

I guess there seems to be one exception to this rule though. I know TORCHD 02 TA is catless with his GMMG setup on his T/A. He also has a chambered Powerstick in his I-pipe to tame the rasp.

My $.02.

I have the Pacesetter off road y-pipe with the flowmaster merge and the interior noise is not that bad ,,my wife will ride in it and not complain.

I would prefer a setup, there are some out there, with
a flanged Y that you could swap in either a cat or a
pipe in 10 minutes on ramps. Or pipe with a cat shell

Pass visual inspection? A resonator can look identical to a Cat, which is the reason why I added offraod with resonators as an option

Thats why I bought OBX headers,they have the Y pipe and the resonators

FLP used to be like that, I had a set in 2000. They even used vclamps on their stuff. I regret selling them sometimes because of the ease of swapping out the cats.

Catless. Cats are expensive, do not flow well, and can clog up. Why the **** would I pay money to restrict my exhaust flow?

Cats are not mufflers. If you've got a problem with the sound, put resonators in. They're cheaper and flow better.

If you've got a problem with rasp, well, stop running a damn y-pipe. I have cheap true duals that sound great, fit well, rarely scrape, and are all stainless.
