Cats or no??

I'm almost ready to place my order for LT headers. Looks like I'm going with 1 7/8" Stainless Works. I'm just torn between ordering cats or not. On one hand I like spending less money and making slightly more power. On the other hand I think the smell may get annoying. I will be running the stock cat-back for a while then stepping up to the aggressive SW cat-back. I think the cats will give me better (louder) sound with the stock CB but may be too much with the SW system. Opinions please.

I have after market cats and even with those the smell is considerably stronger than with stock cats.. I cant imagine how bad it would be without cats at all.. However, mine is a DD.. if it was only a track car maybe it would be OK.

I have the Kooks coated headers with Kooks cats and there is no smell and the car is NOT loud unless you bring the rpm up. That is perfect for me.

I prefer dogs myself, but that's just me.

Kidding. I have Kooks headers, no cats, cam and a Borla ATAK exhaust. It's definitely loud, but I really like it. I thought at first that it would drive me crazy, but it hasn't so far. Mine's also a daily driver.

I need to get a good video of the sound, but here's one when the cats were still on. It got a little louder without them, but this will give you an idea.

No real gains by going catless you will save a few bucks but the smell is awful! Stainless Works appears to be using the Random technology cats which are some of the best.

I have stainless works LTs into a Magnaflow street catback with no cats and mine isn't annoying loud at all even at wot. The smell isn't that bad either. I'd try it with out them and if you think you need them then buy them and put them on. They are easy to install if you decide to. Save your $625 for other things.

Diddo

I'm currently running that same setup (Kooks long tubes, no cats, and Magnaflow Street). It sounds great without being obnoxiously loud, and I get very little smell.

I also have the high flow cats and run them from time to time. They reduce the noise level about 5-10% or so.

Turns on my Jedi mind tricks, "You don't wan't headers or high flow cats. You want to stay stock."

Reaally hope that works. See you Saturday Dan.

I didn't run cats on my previous 4th gen Camaro. The sound is phenomenal, but the smell of unburnt fuel is very annoying. Far too annoying to offset the minimal gain in power. I can't stand that smell...it clings to your clothes and lingers in the garage. From now on, unless it's an old-school muscle car, I'm running cats.

I'm not running cats. No smell here unless you are at idle and the wind is blowing the wrong direction with the windows rolled down. Solution: Roll up the windows.

I will have to go with Hicompression. I have the Kooks LT 1 7/8 (no cats) to stock piping with no mufflers. I will have to say its loud, but even people that do not like a loud exhaust gave it a thumbs up. The price was good for them as well. As for the gas smell, like Hicompression you really dont smell it or unless you are behind your car. Like wise for the wind to but rolling the windows up, smell be gone. Good luck on the choice you make you will not be disappointed either way you go. Put up a video when you get it. I will try and get you a video of mine. Just remember I have straight pipe mainly, still have the resonators.

That is a beast of a car. Sounds good.

Please get cats, I think anyone that goes without is an a$$hole. Even if it doesn't stink in our car it stinks for everyone around your car and it's irresponsible. I'm far from a tree hugger but I'm scared to think what it would be like if everyone didn't have cats. Given the very slight performance gain you get without cats it's not worth it.

How much did a cat delete possibly give you? Cool set up but I doubt the cat delete contributed to it much at all.

Actually the heat will eat through the cats. We've seen cats come apart on the dyno and start flying out of the exhaust.
