Also, I'm the type that likes to drive with my windows open as much as possible. But going completely catless, I don't think I can do it.. which is another reason why I'm planning on putting the oem dps back on.

But here is what I was wondering.
If smell or noise isn't the problem, would you go catless downpipes or catless midpipes?
I just did the same thing.. Kittyless DPs and removed the cats from the mids and welded on a straight pipe... The sound is exactly at around 2100rpm... and also when cold starting, it yells that weird sound for a few secs...
No way I'm getting the cats back on, so my bet is some resonated mids and aftermarket axleback...
