Stock systems usually run less boost and most people don't run WOT too many times.

But a muffler delete wont have drone. I had it for years and never had drone. There was a certain point in the rpms where the sound was just a little high pitched but I never had the low frequency that causes drone with a muffler delete. Weird whay different set ups do.

I’m sure there are people with new ZL-1 and ZR1’s out there running them like they stole them. Is the boost that much higher aftermarket? I’m hesitant to go cat less if I ever do supercharge it.
