Honestly, the drone is there, but it's not horrible. At 70, my Ridge Grapplers are louder than the exhaust drone.

Find someone on ebay with it for sale that has a make an offer option, and low ball them by like $200. Saw one listed for $700, offered $400, and got it for $440 with free shipping.

Bonus, imo it's hands down the best looking cat back out there. Gibson side exit looks goofy as hell with the big ass tips, and the whistling I've read about. Magnaflow has none of those problems.

See my signature for the link to the Magnaflow site for the system for our trucks and also the link to the resonator I'm using.

Anyway I have a rough idea for true dual - have the headers hit a fab’d 2.5” x-pipe and then through the longest 2.5” flow-through pair mufflers I can find (Magnaflow makes a 6” diameter x 27” long round one that should work) with some Helmholtz j-pipes to cut drone and route both tail pipes either out the passenger side either in front or behind the rear wheel.

Should be pretty quiet but loud on throttle I’m thinking. Anyone have any input?

I would say my setup is quiet on the interstate but I have large mud terrain tires that drown out a lot, and 4.88 gears which throw off rpms from stock gearing. For example it drones quite a bit at 60mph but not 70-80.

Without cats, its loud, but your 27" mufflers might help.

Check out my youtube for videos of my setups, I've been through a couple:

Catless makes it smell like an old truck or atv, and added rasp. I might be adding two cats to deal with the smell, but I don't mind the rasp.

Still learning a true X crossover pipe doe...seems like more room to add dual long ass mufflers/helmholtz resonators after.
