I traded the Flowmaster American Thunders for a set of Borla Stingers and installed an off road H last week. I know that the rear 02 sensors are turned off with an aftermarket tune, but will I need to update my Brenspeed tune at all since I'm catless now?

you just need to turn off the rear o2s as stated and as far as performance goes you are looking at minimal gains but it should help just a tad. It is a good supporting mod for future mods though. Good decision if you ask me.

It seems to sound different than the exhaust clips that I listened to prior to purchasing. Definitely alot more hollow resonance sound than I was expecting. Sounds like it needs a set of resonators installed to help it out. It screams when you put your foot in it but is borderline obnoxious at certain rpms where it resonates the worst. When it resonates it isn't a drone like with most set ups...it's almost a raspy metallic sound. It is the worst when you are accelerating hard at around 2500 rpms. This is all coming from hearing it inside the cabin though. I haven't heard it from the exterior. I need to find a digital camcorder to play around with.
