I am going to put my new Borla cat back exhaust on my SVT and was thinking of removing the cat. I know this will throw an engine code but will it cause the car to run Lean????

^^Thanks again for the springs Pumkin, they will be put on this week and I'll be wrapping my header.

Just extending the pipe. I have a rattle and looked everywhere and believe it's coming from the cat, if thats even possible.

no problem I wana see pics of your car when you put them on.

jus go to a muffler shop and tell them to make you an orp

and have two bungs welded into to it for your o2 sensor.

you need the front one on or your car will run like shit.

Its possible it will throw a lean code. Just reset them, they might stay away if the adaptive control does its job. I'd pull the cat & reinforce all the heat shields. I wouldn't remove the shields because you might cure the noise, but will create other problems like proper cat lite off in winter and in summer radiate too much heat in surrounding areas.

Ok, so if I get an orp pipe made I just need 2 bungs for my o2 sensors and NO cheater harness to keep it from running lean? And if it does run lean just reset it how, by unplugging the battery???

And I will get some pics up Pumkin when it is lowered and exhaust is on. I'll send you the link.

I checked CFM but I didnt see any on their page, I dont know if they are still selling them.
Yeah, I just called a place online and they haven't had em for awhile. Oh well, I'll get all new exhaust with an ORP put on and perhaps get the "mil" later. I'll just have 2 bungs put in. Thanks for all the help guys, and Pumkin especially.[wave]

Klodkrawler03 I believe is his s/n but he made or had one made he sold it to me I'm sure he has pics he could send you to give a good idea of what a custom made one looks like.

We need to get together some time. I have a CFM high flow cat and I'm pretty happy with how it performs and sounds.
Lets do it. I'm trying to get together Friday or Saturday with another 502 member for some pics. Let me know. PM me here or 502 (Venom)[ffrocks]

We have a great performance shop by me that is doing it. No need, but Thanks a lot[cheers]

I've always been under the impression that deleteing the cat wont throw a lean code (or make it go lean)

the front O2 sensor is the one that helps regulate fuel in the engine, the 2nd O2 (after cat) is there to let the ECU know that the cat is working fine.
