by adding a high flow cat will it kill the smell? if i drive with the windows down it smells pretty bad....

What did you do to make your car dump fuel in the first place? Adding a catalytic converter will help convert the hydrocarbons into carbon monoxide which will in turn, decrease the smell of gas, but this is only limited depending on how rich your car is running. If your car is running extremely rich you will essentially burn out the catalytic converter as well as spark plugs and the problems are endless.

maybe you have an exhaust leak towards your header or spipe. becuase if you are driving with the windows down... and everything is bolted correctly, it would be comming out of the tip of your muffler and you wouldn tbe able to smell it. did you put back that little donut gasket between the header and the spipe?

Is your CEL on?

biGhuK · 03-27-2007, 08:33 PM

if you're running real rich you will see an excess of carbon build up on your rear bumper and exhaust tip in some cases. And like said before, check for exhaust leaks and of course if you're throwing a CEL then get the code pulled at autozone and come back here and post it.

no cel, smell comes from exhaust

Sleep3r · 03-27-2007, 09:46 PM

i did the anti fouler trick, used the donut gasket between the header and s-pipe also

Sleep3r · 03-28-2007, 04:13 PM

sooo if i don't have a CEL i shouldn't worry right? thanks in advance

biGhuK · 03-28-2007, 04:54 PM

yeah you should be fine, log your MPG and see what it's running.

Sleep3r · 03-28-2007, 04:58 PM

just start eating hot pocket lean pockets.

Thats about 75 miles less than i'm getting per tank. I'm averaging 29.5 miles to the gallon with an HKS axle back and K&N CAI. That may be normal for the header application, anyone with experience on this wanna speak up?

StealthScion · 03-28-2007, 05:18 PM

its pretty tough to just guesstimate that you are running rich, especially if you are just NA w/ bolt ons, i highly doubt it.

you get 345?!?! i got 270 right when the gas light lit up so maybe i had a lot more...i usually don't drive it pass the light because of past experiences

biGhuK · 03-28-2007, 08:02 PM

Yeah man, I average about 29.5 MPG.

JDMonkiTC · 03-29-2007, 01:27 AM

take ur car to a local tuner shop and see ur air fuel ratio

Whocares05050 · 03-29-2007, 01:34 AM

Your not runnign rich with just bolt on's.

come on man, seriously. dont worry about it, you cars exhaust stinks because of the bolt on's. Have you never moded or been around a race track or any other moded car?

Dont mean to be an A$$, but you will be perfectly fine.
