Anytime you open up the exhuast flow, you drop back pressure which is going to reduce your low end performance. It's a trade-off
Most exaust companies focus on wide-open performance numbers and not on the low-end. I ended up trashing my first exhaust system to go with one that had better low-end performance.
Also, it may be a good idea to swap out the MAF sensor for one that can meter the air better. The OEM unit can only meter within a certain range of air and you may be outside of that range if you have not changed it out.
If your exhaust is true duals, you may benefit from a cross over tube slightly smaller than the main exhaust pipes. This will give you some low-end back.

I am also hoping to richin the sound up a little more. Don't get me wrong...the borla sound awful sweet....maybe one or two octives will satisfy me. ARE WE EVER SATISFIED? DO WE EVER GET ENOUGH?
