Hf cats vs. no cats

Ok so other than price is there any difference to the car (performence or sound) between the two?

Cats are a bit quieter and deeper. No cats are raspier, and make anywhere you go smell like a drag strip.

No cats will add better power in combination with Long tube headers. With your mods, you might see up to 5hp gain. Plus without a tune you'll lose TQ down low and gain high in the band only.

Hi flow cats or green cats don't like boost. Boosted motors burn up cats . I too like the drag strip smell. No cats are free. I am a big fan of the cat delete. At least with my car, nothing raspy about it, matter of fact the exact opposite is true.

Now if u get a cat delete the cel light turns on, does it effect any warranty work that might need done as well?

If you tune it it will void the warranty.

If you want to have headers without having to tune, you would need green cats since they don't throw a CEL. Only problem is that Green Cats cost your right arm...

You will most likely have a cel with hf cats and long tubes as well. That means it won't pass inspection(in most states). If you tune it it will void engine warranty. Double edged sword of modding the engine past cai and catback.

It's not bad. AdamZ has been running no tune and headers for awhile. The green cats are always an option as well.

If you don't want to void any warranty I agree with MikeyG don't do anything. There is no point to messing with the cats. IMHO

The setup I have right now sounds awesome the only problem is I like how the zl1 exhaust looks 10x more. I wanna switch to the zl1 but keep the sound

Your car is a '10 so the warranty should be going out anyway...

5 year 100K warranty on powertrain. he still has a few years/miles I'm sure. HF cats from the stock manifolds will get you some extra HP, buuuutttttt. rumors have it the JBA ones usually trip the CEL. Solo cats have a better history at not doing that. Personally if you aren't willing to go all out and get headers/cats with a tune then don't do it at all. That setup will net you close to 50RWHP with an intake already installed. Cats alone will maybe get you 15-20ish.
