So before anyone goes bashing on saying to buy an exhaust or what not I own a 335is and I love the sound but I want it to be a tad bit louder....anyone know if removing the secondary cats would be a good move towards this solution without the headache of drone inside the car during cruising?

Why not just put on an aftermarket exhaust. That way you can replace the exhaust when the time comes. Its not that hard to do. Sometimes the bolts can be a pain but a little WD-40 can help loosent them up.

any other suggestions?

You won't get drone unless you delete the muffler so go ahead with the 2nd cat delete.

If you planning to go with catless downpipes in the future u will get a drone, if just secondary cat delete no drone, i had secondary cat delete when i put catles downpipes i got a drone between 1500-1800rpm not too bad
