I'd be interested to see proof of this loss of low end anything by simply removing the factory muffler section. The stock cat is far more restrictive and has a greater effect on exhaust flow and pulse timing than the muffler ever will, unless the cat is removed. Doing a muffler delete is not going to make any noticeable power, but it does remove a lot of weight. Even a cat back exhaust (leaving the factory cat in place) only has a minor effect on performance, and most of the gains come from loss of weight. Only by replacing the entire exhaust system, headers included, with a pulse tuned system designed to maximize exhaust gas scavenging and properly time exhaust pulse vacuums will you see any real power and torque gains.
I'm trying to find the article I've seen that spells out the major objectives, and differences, in turbo exhaust systems and NA exhaust systems so I can link it here, because it does a better job of explaining it than I can from memory.
