Very pleased with results--I don't have any objective evidence, but certainly seems to have more pep, especially at low end.
The AFE intake is the full box, but doesn't seal against the holes in the fender that the factory intake mated against. Instead, it just has a large opening facing the fender--probably OK I suppose. Also has a 'snorkel' type thing protruding from the bottom of the box, which then curves so the opening faces forward. Unfortunately, the snorkel opening is partly blocked by one of the many random parts bolted to every flat surface on all new vehicles; the rubber protective flap just behind the device is right against the snorkel opening. I'm thinking the best fix might be to just cut the curve from the snorkel, so the opening faces down... Might not be the best in dusty conditions, though.
I haven't seen any discussion on Aero mufflers--their web site is www.aeroexhaust.com --I believe the company is better known for diesel exhaust and has only relatively recently begun offering parts for gas engines. The Aero muffler is definitely louder on acceleration, and when the vehicle is started it sounds downright mean--really good tone. Haven't had on the highway for any distance yet, so not sure how much drone will be experienced. Aero also makes a resonator that is supposed to quiet the system, and I may have to add one. The guy at the muffler shop thought I'd just as well try it without and if I wanted it quieter he could then add the resonator. BTW, any one in the Denver area wanting some exhaust work should check this place out--Bud's Muffler Shop--I was very pleased with their work, and Bud, the proprietor, was willing to take the time and discuss different options and make recommendations. The new muffler with install was less than half the cost of a cat back system, and since my factory exhaust was 3/3.5" a full cat back system would have been unnecessary and redundant.
Anyway, as previously stated, I'm pleased with results. Though I know the psychological aspect of more exhaust noise can make it difficult to differentiate from a real gain, acceleration really does seem noticeably better. No figures on mileage as yet, having only driven 100 miles or so. I'm adding a Hypertech program next, and am hoping for better gas mileage as well as some add'l power.
