CJ Pony Parts what loud axleback sounds good to you ,not just loud to be loud ?

[@grifftech]

Going to do a Flowmaster Active Exhaust?

[@StevenNeidlein]

Hey bill are these louder than roush axle backs ?

[@SamAndAdamsFishroom]

Just had this put on today on my 2018 Mustang GT convertible, birthday gift from the wife. I had it done at a custom muffler shop and had to do some cutting due to the bracing underneath for the convertible. Hands-down the best decision, this exhaust sounds absolutely amazing, has the deep rumble of a classic big block, and the exact sound I wanted. Recommend this 100%, in my opinion the best sounding exhaust for the coyote!

[@demetriawright1528]

Did you keep the resonator? And does it get raspy in the higher RPMs?

[@SamAndAdamsFishroom]

@@demetriawright1528 I kept the stock resonators, it’s still very loud with the resonators on. It still maintains a deep tone without raspiness at higher RPMs.

How do u like it im ordering one very soon

[@thomasdouglas9562]

Sure would cool to see a DB meter reading for the factory exhaust and the exhaust mods. I know that temperature, humidity, and distance all affect the outcome, but it could help remedy some of the "How loud is it tho?" questions. It would, incidentally, help me make my decision on which cat back system I'd buy.

[@cjponyparts]

Thanks for the idea! We tried that at one point and most people didn't really know how loud a certain db reading was but maybe we will try again.

[@lukebmx137]

This is exactly what I’m looking for! I don’t want to be too loud. But I want to have a deep throat punch when I take off and this is exactly what that is.

I think this sounds better than all the different systems you tried on your manual 'stang, nice! This one would be a keeper for me.

[@drive55not]

I installed the full outlaw cat-back on my 2018 GT, It's LOUD ... Gotta take it easy in the mornings so not to pissoff my neighbors ... Also, these things aren't called DroneMaasters for nothing,, they have big drone that gets tedious when you're cruising 80mph on the interstate. I knew they were going to drone but picked these over the Corsa Xtreme cause I ilke the looks of the Flowmaster Carbon Fiber tips, At some point I'll cut the Outlaw mufflers out and splice in a pair of Borla mufflers [already have em] to kill the drone.

[@vlKenzo]

I drive 70 miles to work on the LIE. I watched both videos. The axle back and then the x pipe add on. I think I might go with just the axle back. You said it doesn't drone on the highway. I have loud pipes on my bike. Loud, but not obnoxious. If it doesn't drone and isn't obnoxious I can do the commute and not have ears ringing. I have read some reviews here and there where people said it DID drone. However, it's unclear weather they just had axle back or the whole kit. Also, most were from earlier years. Is this latest version been quieted down from years past? Say 2015 to 2018?

just installed a Flowmaster outlaw W/ active exhaust on my 2018 mustang gt , Sounds awesome but there is Drone

[@drive55not]

I installed a set of MBRP LT's a couple weeks ago and mated the Outlaw catback to them, That combo was unlivable on the highway, 2500rpm in 10th , my ears would ring, nearly start bleeding and teeth would start rattling... I had a pair of Vibrant 1792 resonators welded in as a helmholtz resonator like MBRP does on their race axlebacks and that killed most of the drone, 2500 is actually drone free now.

Do you have a video? Looking to add this with active to my 18 with H pipe

[@otto7707]

Hoping you guys would do some videos with the axle-back that are for the active exhaust version... No one has videos on the active exhaust versions of these types of axle-back exhausts. Like it would be good to know for buyers who have active exhaust how much the different modes either quiet or increase the volume for driving conditions like long road trip in normal or quiet mode as compared to sport and track mode.

[@cjponyparts]

We do videos based on demand and vehicle availability. We do not have a shop car with active so both the installations we did were outside cars and they both wanted cat backs.

[@otto7707]

@@cjponyparts unfortunate but understandable. Just wish there was more active exhaust videos out there. But I am grateful for everything you guys do post and I have made a few modifications based on your videos.. like I bought the roush x-pipe for my 2019 gt because you guys did such a great review of it . I look forward to more videos !

[@lilhomiejosh]

How bad is the drone? Would it be unbearable for daily driving?

It is quite boomy for sure on the highway, really depends on the owner. It was a bit much for me but we have lots of customers who love it.

Exhaust should not have any affect on your RPMs, especially that much.

Hey Bill, how does this compare to the MBRP muffler delete in terms of volume and deep tone?

Could this be put on the GT’s with the active exhaust system?

[@cjponyparts]

It would not work without getting an active system delete from AWE.

[@honeymir805]

CJ Pony Parts Just to clarify: getting the Outlaw exhaust will delete the active exhaust function? Or you have to purchase a separate active exhaust delete for the Outlaw to be able to be installed?

[@cjponyparts]

@@honeymir805 You would need the active delete plug from AWE to use the Outlaw or you will get a dash light. www.cjponyparts.com/awe-exhaust-valve-motor-bracket-with-active-exhaust-2018-2019/p/HW4213/

Hey there, I considering a pair of Outlaws for my 2019 5.0, I'm concerned about fitment issue though because a while back I took off the OEM resonator and replaced them with a couple of 18 inch cherrybombs , do you think I would have fitment issues by adding the Outlaws?

[@cjponyparts]

The Flowmasters fit fine, as long as you did not move the exhaust when you installed the cherrybombs you should be fine.
