I just installed a set of pacesetter long tube headers. I have a custom y-pipe without cats and Borla exhaust wide open. Now when I'm stopped at a light or just letting the car idle I can smell the exhaust real bad. My car was tuned with mac headers and the borla exhasut wide open and I never smelt the exhaust. What can I do to correct this problem? I have edit and autotap.

Thanks for the help.

Unless its just the paint burning off (or the metal), I'd check for a leak somewhere. That's all I can suggest. I don't smell a thing in my set up.

Did you have the cats off before or did you just remove them when you installed the new headers? Camaro ChriSS is probably right though, I bet it's just a leak.

yah if you had cats and havent yet deleted the rear o2's through ls1 edit it would tend to run rich...other than that i dont know what to tell you.

I have smelt gas ever since I took off the cats but you may be able to get rid of it with some tuning.

It's the same set-up I had with my Mac Headers No Cats, Borla wide open. I've turnd off the cat over temp in edit. Also the rear 02's are turned off. I'm not setting any codes. It's so bad some times if the wind isn't blowing that my eyes start to water.

Thanks

The exhaust smell is coming from the tail pipes. Could the headers lean out or richened up the car after the install. If the 02's weren't into the header far enough cause a problem? When I installed my 02's I had to use my dremel tool to in=order to get the 02 in. Maybe it's not into the header far enough.

Thanks for the help.
