siddo - Asked the dealer, and yes, it is stillen who makes the cat back exhaust. Looks like 2 to 3 weeks to get it in, but it is on order. According to the performance parts manager, he is saying 10 to 11 rwhp for the stillen intake, and about the same for the cat-back system. Combining the two, since you'll be moving more air in and out, is around 25 to 30, again according to the dealership. My thought is that it would be closer to 15 to 20 in total with the two mods at the rear wheels. He didn't have any torque numbers, but 7 to 10 wouldn't be out of the question. I put about 50 miles on 'er today, and it is definately a nice ride. Not an overabundance of torque in the low RPMs, but above 3k, that 3.7 comes alive. Headers and supercharger will complete the package (I believe Vortec is 6 months away from a revised supercharger to fit the 3.7), and I understand it doesn't require a hood modification. I'll post some pics tomorrow...she's resting from her first day on the job.
