Rear cat swap debate

[mavrick1903]

Wondering what the effect of a rear cat swap would be? Louder? lower tone? what will it do to hwy drone at speed? throatier in town?

Current setup:
2007 v8
Doug Thorley SS Headers
Magnaflow SS front cats
OEM rear cats and Y-pipe
Gibson SS exhaust with (shop adjusted) side tip.

Thanks for your input.

I only have an aftermarket mid section/muffler, removed rear resonator, and then deleted the rear cats and raised the crossover section so I could mount skid plates higher.

I immediately noticed more drone in town with the removed cats.

DT is coming out with a new y-pipe with resonators for about $500

Has anyone heard of a timeline for this?

I would highly recommend getting rid of the restrictive stock y pipe. Especially since you already have the Doug Thorley headers. In addition to the DT y pipe coming out, take a look at the URD Y pipe if you haven’t done so already. Highly recommend it.
