Lost my low end due to oversized exhaust?

So, about 15 years ago when the original muffler broke, I replaced everything with a catback 2½" kit from Dynomax. Oops. Now it appears that I've lost all my low end scavenging and torque. The good news is that she pulls really hard a 5k now...

Anyway, what is my most sensible option to re-gain my low end back, or should I not bother?

I personally like the top end power but I race my car. Its up to you, would you rather have low rpm Tq or high Rpm Hp?
