anyone know the length of the offroad pipes for the speed engineering longtubes? im ordering a set and id like to use universal hi flows if possible (more available and much cheaper than say tsp) but i need to know how long of one to get since there are a handful of sizes available.

Be careful on buying"cheap" cats as they have a tendacy to fail much quicker than the "expensive" ones would. Internal material come apart and get clogged up and cause lots of problems. I have read on here and seen pics of the failures. Just be careful..

is there anything wrong with flowmaster in this regard? they have a 200 cell metallic substrate cat that's actually the cheapest on summit, 82 bucks. plus I'm not going for big power and fi, absolute Max I think would be 550 BHP and that's pushing it, it would be more like 500-525.

Those should be alright for your app. I think all the HFC's are 200 cell, just made from different material. The stock rate at 600 cell if I'm not mistaking..
