Low end torque
 

How much low end would you lose by replacing the stock pipe with a Bassani X pipe, however, leaving the catack alone, on a 2000 GT?

While I've had similiar concerns in the past, the fact that the 99-00 engines are putting out much better numbers and that the exhausts are much less restrictive stock, I think you'll be fairly safe as long as you go for an X-pipe with cats...

I have spoken to several users of the exhaust, and responses have ranged from absolutely no torque loss felt to a small loss in torque but a better gain in horsepower.

To be sure to keep some of that torque and to keep the smog man happy, I would go with the x-pipe with cats. I have yet to hear someone dissatisfied with the mod....

Just my opinion...

98 GT
Dyno-Max cat-back exhaust, 3.73 gears, Steeda shifter, Ford Motorsport Underdrive pullies, 87mm MAF and Roush cold air kit...

There will probably be a small amount of torque loss. You can offset that with 3.73 gears. That's the route I'm going to go (pulleys, x-pipe w/cats, and 3.73s). I need to hit lotto so I can bu a Vortech with the intercooler!

Ok. Thanks for the information!
