Thoughts on Shorty Headers
I'm just wanting some thoughts on what everyone thinks about shorty headers?

Nothing wrong with them, but you still stuck with the worst part of the stock exhaust and that would be the primary cats. LT gets rid of that issue, hence they are popular. But you say I'll do shorties and then CA front cat deletes... you rapidly get to the price of LTs.
Plus because the factory already comes with an excellent set of shorties, it is HARD to make more HP here. So nothing is "wrong" with them. They just fix a non-issue. I like the Hooker shorties but would never buy a set.

Waste of time. You have Tri-y manifolds OEM.
There are photos online.

Here is a pic. Your not going to gain much with shorties. Its LT or OEM being your best choices for the money and time spent.

I got a set of JBA shorties when they were on sale. I still haven't put them on though, waiting for warmer weather. I don't think they'll make a noticeable amount of power. Like others pointed out, cats are the biggest restriction in the stock exhaust system. I don't want to remove them; cars start smelling and noticeably spewing shit into the air - laugh all you want, but I care and don't plan on racing for pinks... so I don't need the 20HP and don't want to spend big $ on good high-flow cats.
I'm just looking for a different, hopefully better , sound. The design of JBAs is 4-into-1 right at the last moment before the downpipes, and that's where the cats are. They're also more equal length, so it should make a slight difference (yes I know LS/LT firing order makes fully equal length headers unnecessary unless you go 8-into-1 or 180*). I'll post my thoughts once they're installed. Stock JBA

The car has 4 cats anyway the front ones only light off slightly faster. One Moped in China pollutes more than your entire block because of the two-stroke design. Nutshell... relax.

If it's just sound you want, there are much better ways to go about that. muffler delete, secondary cat delete, etc. |

I doubt you will notice much difference in sound with those shorties until you address the primary cat pipes

I would ditch the stock cats before you worry about the manifolds. The stock manifolds have come a long way and you won't see any power gains with shorty headers. Just bite the bullet and go with some long tubes. That's were the power is, that's where the rumble is. We have plenty of affordable options, especially if you use code CAMARO6 at time of check out. Some worry about warranties but we have plenty of dealers that have zero issues with long tubes.

Yep Juiced has hooked me up before, and to the guy that wants to save the planet, there are green cat options too.
You will see that even 825 HP ZL1 keeps the stock exhaust header.
