I have some long tube headers with a new short h-pipe w/ high flow cats. I don't really need exhaust cut outs, my exhaust flows freely, but I want it to sound real mean on the weekends. If I put some exhaust cut outs right behind my headers (infront of the cats) will I get a check engine light, and will the car run lean because of this? This is the order it will be in-> headers, front O2 sensor, exhaust cut out, catalatic converter, rear O2 sensor. The way that I understand it is that the rear O2 sensor won't detect any more O2 than usual because the cat is still there, it won't be getting hardly any oxygen. Then again the cat might not heat up and won't burn the extra fuel. That's all I can really think of. I hope that some one can help, I don't want to cut up my nice exhaust set up to find out that I have more problems than its worth. I can always put the cutouts behind the rear O2 sensor, and I know that won't cause any problems, I just want it to sound really throaty. Thanks a lot for any help.
