Cat Delete
I have read several posts here where people are removing the secondary cat and resonator in the exhaust. I plan on moving back to FL in 17 and they do not have emissions testing. Is it possible to remove both cats and then run a o2 dummy so that the ECU will not throw a code ?

Welcome to the forums. Nice car!
I'd personally just remove your 2nd cats and place in straight pipes, leave the res and be done with it, fully straight piped cats is insanely loud and it stinks really bad on WOT. You can get your sensors disabled via tune. Don't bother with a x-pipe/h-pipe people buy them then come post on the forums that it doesn't sound right.

Yup, that's my plan man. I sounds good stock so I think removing the 2nd cats will make it sound a little better, I don't want it to be crazy loud so I think i'll leave the res on. I just have to find a place that will do the straight pipe for me since no one around here seems to want to be able to do that due to the California emissions laws and removing any cat.

I had a 69 Camaro with a 383ci and 3in straight pipes into 40 series flowmasters and that was not too loud. I understand that a C63 is completely different animal but think "loud" is a matter of personal preference. I was unaware that you could disable the 02's via a tune but that is good info to know.

I'll be in San Diego aroubd Christmas and you can hear my catless LTHs if you want. From the setup you had on your camaro, I'm not sure a secondary cat delete will be enough for you.
Edit: I see C SEXY 3 already offered up his header setup.

Okay, LTH is another beast on its own. How loud is that setup compared to mine (2nd cats & res delete to straight)

I'll be honest. I have only heard stock and my LTH/x-pipe setup. I have to cold start with the garage closed and tons of people give me a thumbs up in traffic. The occassional old person will scream at me or give me the finger. Let me finish up my before and after video and I'll post later. Inside it's still reasonable when puttering around town. Even at WOT my mom said it wasn't too loud for her.

Honestly the best part about this car is how it just gravitates people to you. I've already met a bunch of car enthusiasts in my time owning it.

dlowery21, are you explaining to them that you are talking about secondary cats, and not primary? Just curious. Im not in California so I dont know about your laws. If you are, you prolly just need to ditch the mainstream big name shops and go see a guy named Hector who has a torch. Not a big job.

Dude. He may buy a car, next year, and it might be a C63 if he can find one for 5k under market value, he might mod it, of course that too would be next year, and he might be moving, also next year, and it might be to Florida. 2017 could be massive! How else is he gonna plan if we don't answer all the hypotheticals? He has questions about enviro testing in a state he doesn't live in for a car he doesn't own. Fair enough. Just cos they are all asked and answered and there for the searching that shouldn't keep you from investing your personal time. I may have time in 2017, and then I might get around to these, and maybe you should help, Mr. High Horse.
