To each his own, I like it and it sounds great when I accelerate, just what I wanted....

Eagerly waiting for a sound clip!

I love my GM performance exhaust sound!

[MiamiBlueCamaro]

Ok let me rephrase "my sound like crap" with this.

The above post is out of context, later in that post, after 100 miles and removal of the 2nd cat, it Sounds fantastic:

I am glad that you are satisfied but i am not going to pay GM 900 dollars for that very quiet "sound". Also i am not going to remove the 2nd cat it maybe illegal in some states and may throw a MIL (check engine light).

[Glen e]

Understood, but it does not sound like "crap" , just correcting that. And welded correctly, there is no CEL whatsoever. The cat delete did not make a huge diff, it sounded good after it broke in. I have no Emmission Prob in florida. YMMV

Cool, i am waiting for the Borla Exhaust but i guess they are doing the Camaro turbo first!

Rang em up yesterday, they said check after my bday. Right now it's slated for mid to end of the month.

indeed it will vary. Does Florida even do emissions inspections?

The removal of a catalytic converter is not allowed due to federal anti-emission tampering laws. It's up to the state to enforce them but you're breaking the federal law regardless.


On a somewhat related note.. I wonder what GM's reasoning was with putting an un-monitored cat downstream from the monitored cat. They must be using it to reduce how much pollution they are rating the camaro at for federal regulations, but by being un-monitored, the emissions tests are only going to give them what the first set of cats are outputting anyway since nobody uses the sniffer test anymore cept obd1 cars. Just seems to me that both should be monitored if you're not gonna sniff test.

I'm suspecting it has to do with exhaust flow could be wrong, but it's surely possible.

Remember when mishimoto did the testing and found out that the crimped pipes near the rear have no effect on performance?

The second cats, along with pollution reduction, could have something to do with exhaust flow.

Think how lava flows in lava tubes, first.

The same principle can be applies to ANY form of matter, even gasses. If you keep something Hot, it flows faster and more efficient. The minute it cools down, relatively, it becomes more dense and moves slower.

I think they also mentioned something about em, and beating a guzzler tax or emissions deal on the v8s with that design too.

Is there ever going to be a video for this?

[adrian1996]

Good job guys. Just waiting for the video to come out and see if they are the right fit for me

Personally, i have NPP on my camaro and i really like to sound of it but sometimes im just wanting more sound so thats why im going to order the ATAK soon. and plus, Chevy is probably going to charge a couple hundred just to get to rear fascia to fit the "quad exhaust tips" so might as well just pay for NPP.
