Again it all depends on the headers, not all headers are created equally, their tuned for different applications. On the Viper there's so much low end torque (488ft lbs stock) that loosing a bit on the low end probably may not be a big deal depending on what your doing wiht the car. I took mine to Thunder Hill and it was an absolute blast, sounds like a full on race car with the (then) new exhaust.
What headers are you running ? I'm also running a full billy boat exhaust, sans cats.
