I love my muffler delete....pure sex under WOT and plenty of pop on decel. My favorite thing to do is wot under a freeway overpass

 

So far no louder than my 64 Malibu with 30" glass packs.

Yes, I also love to accelerate full throttle in an underpass to listen to the echo.
Time will tell if there is "drone" noise at cruising speeds. The 2004 SSR with a Magnaflow does "drone" at 55 to 60 mph under load (in OD) more rpms cures it.
MUST DRIVE FASTER!! LOL

 

There is some drone at around 70mph, but its not too bad. You can play around with the RPMs like you said or turn up the radio

 

ran some errands today
I like the straight pipe, It can be a little loud but the Hot Rodder in me likes it!!!

 

Muffler back, Too loud under load, Drones until downshift. Small muffler toned it down and now has a more mellow sound.

 

Hey la hey la the mufflers back!! got a vdeo of that?

 

what muffler did you end up with JimBob

 

Just installed a Magnaflow today and really happy. Not to loud and no drone noise.

 

got a used Magnaflow from another member her, not to loud, not to dronie, it's just right!!
