Hi:
I know I have put this in before but has anyone else had problems with headers leaking exhaust out and air in? I fixed the prob. of the exhaust leaking out with the proper gaskets , but I have not found the prob of air leaking in? The engine is running richer than before I had the headers put on.
Has anyone else had this problem? HHHEEELLLPPP

I guess I would have to ask how you know you are running richer now than it was before the headers? Did you do a dyno tune and have the AFR data? Or is it your exhaust smell? or what? If it's the smell and you removed the cats during the install your exhaust will smell like it's running rich but it may not be.

Headers

Hi:
I see that it is running richer because there is more carbon on the tips and the fuel mileage is slightly lower. I have the high flow cats with the exh system.
Thank You
Ed
