Sedan Stillen 2003 droning at lower RPMs

the first thing i did to my 04' exhaust was the axle back HKS. not much drone, imo, and sounded good. i got tired of it and wanted something louder or just something different. i took out the stock midpipe and resonator and repalced it w/ a mandrel bent 2.5 inch midpipe and magnaflow/straight pipe premuffler. now i have GOBS of drone and it's really loud after i've been on the freeway for a bit.
so, i initially thought the drone resulted from the muffler but w/ our cars, i think a lot has to do w/ the midpipe and resonator. just my 0.02

I drove it today on 407 and 404 this morning to work and have to say that this exhaust is PERFECT for a highway driving. It opens up after 3000 RPM and sounds great + the power IS there...
Overall I think I lost some power/torque at the lower RPM but gained loads over 3000 RPM...
I think I can get used to it...
We went to Rogers Center for the Disney on Ice with my daughter and at least three car alarms went off when I started up the car to leave LOL.
So I guess I'm starting to like it and will just install a bigger resonator (+1 Cremaster) once my ears start bleeding from the city driving.

i had the same problem with 1st gen stillen exhaust - and with crawford cats and hears it was super-bad. at 2.4k rpm it resonated with the car's interior (especially plastic in the B-pillars) and it was pretty annoying. no way to get around it - get a different exhaust.

What I'm going to do instead is resonate it properly... another $300 out of my pocket.
