well i'm so worried that if i connected the sensors to the headers and pipes i get check engine light. i'm going to get my PCM tuned so shall i ask for O2 sensors delete?DevilYellow said:Your car will be really loud.
All the calibrations for saudi cars I have seen do not have the rear o2's functioning.
thanks alot man, oh btw how does it sound running LT's with no cats? is it extrmly loud? because i'm goin to run the SLP loud mouth with it , i like loud sound but not annoying .2Cool said:I have the headers with no cats. My check engine light is on currently, awaiting HP Tuner software to turn it off. I purchased the headers at Next Level Performance (formerly Norris Motorsports) in Orlando. Speaking with Mike Norris, he told me that the check engine light for the headers effects nothing in the performance of the car, it is only stating that the cats are not operating properly. So no timing pulled, no fuel enrichment, nada, just an orange lighted engine silhouette in the dash. He mentioned that he has dyno checked this to verify no performance change, light on vs. light off.
So turning the rear o2s off is fine, but it won't hurt not to do so.
DY has told me that running headers/no cats/loud mouth is gonna be LOUD!. probably enough so to me in trouble with the local police. which is why i am thinking headers/cats/loudmouth.Dark said:thanks alot man, oh btw how does it sound running LT's with no cats? is it extrmly loud? because i'm goin to run the SLP loud mouth with it , i like loud sound but not annoying .
oh cool, btw are you runing SLP loud mouth or other cat back system?CMNTMXR57 said:Yes, mine runs like that. It isn't all that much louder than with cats. Catalytic converters aren't mufflers per se. They more or less tone the exhaust some. Without the cats, you'll get a more "Raspy" tone to it.
As to worrying about your SES light, just buy a set of O2 simulators that plug into the post cat O2 wiring to trick the PCM into thinking the O2's are really monitoring and switching or have someone with LS1Edit "fix" them.
They have full cat back and the LT's if that is what you mean. They use Cherry Bomb style mufflers. It will be Loud.DANSLS1 said:Does stainlessworks have a full bolton exhaust available? I am split between putting the LT's on and leaving the stock resonators and mufflers and doing the whole thing stainless.
