For those with O/R pipes....

This is probably normal considering I have no cat's, but my car REEKS of fuel whenever I run it hard. I would not be all that concerned but I am noticing it just as strong at highways speeds. How the hell is the exhaust getting back in my car that strong @ 80mph? I checked for leaks at the headers and Flanges and it all seems tight? Should I get it tuned to make sure I am not running too rich? Like I said, this may be normal for O/R exhaust, but I thought I would ask for opinions.

Its not normal to smell it at those speeds with the windows up. WIth my O/R pipe, at stop lights and when parked it would reek. But at highway speeds, deff not. If your running rich its not a bad thing, better than lean. Id just get it checked for exhuast leeks, maybe you missed one ??
 
Its most likely an exhaust leak bro. Even if it 'looks' tight, you could still have seapage somewhere. At those speeds, no way should yuo be able to smell the exhaust, unless you have a leak at your manifold to midpipe junction on on, or both, sides of your exhaust.

Not only is it reeking of 'gas' but you're also getting a mouthful of carbon monoxide, which is NOT a good thing! Until you get it fixed, I would keep your windows down at least just a hair at all times bro.
