im on the fence post on this Y,reason-the idea is a great one,but they should have made it 2.75" or 3".so the gain s from this will not as much.

the idea of a "bigger" Y is a good idea and wish someone would built one and sell it.i think there can be gains from a good built Y.ADM out of north tx built 5 3" Y's and UNTUNED they made 12hp 19tq just bolted on.it also leaned it out as well,so tuning it made a few more hp

so with that said i think you might gain a little with this but nothin major.

 

for the money this cost, your better off getting the uncoated pacesetters and ORY.

But thats just my 02.

If your in a state where LT's are hard to get past the smog police, this might be worth it with some good shorty headers.

 

LOL, doubtful, the biggest problem with the LT's and smog laws are that the cats have to be relocated to accomodate the LT's. With this setup the cats are completely gone, definitely wouldn't pass a visual. In NJ, they slide mirrors underneath the vehicle to see if the cats are there.
