It'll be catback. I already have the single midpipe installed so completing it with the axleback.

Installed the axleback yesterday to complete the full catback (single non resonated mid-pipe) and snipped a quick video from the first start up. Loving the sound so far. Working on a cinematic rolling video this weekend.

How would you compare single midpipe + OEM to this full system? What kind of sound changes did you notice?

Hard to say definitevly based off only driving it a few times since install. Keep in mind the exhaust will break in over time but Initial thoughts are:
-louder than single mid but not over the top. (I have a newborn and he slept fine going to daycare)
-more tone and a little more rasp
-it lost some of the roar towards the top end but nothing bad
-lower parking lot speeds you can definitely hear the exhaust a lot more (valves open)
-comfort and valves closed I am getting some slight drone between 2k and 3k.
-burbles are less pronounced but I think this may be due to the exhaust still breaking in.

Overall I'm very happy with it. I have a friend with a full valvetronic so plan to compare sound/ tone. I'll do a more in depth review once I get more seat time.

And you have the MAD single midpipe with this correct?

Curious on this paired with an AA single midpipe.

Stock downpipes this is just a catback exhaust.
This is the MAD full catback now. I've had their single (non-resonated) mid pipe on for 10 months or so now.

Gotcha, I'd say pretty close I think the AA single and MAD single look very similar

Awesome your video will determine whether I pick up the full catback next week haha. Price is incredible compared to the rest of the overpriced systems on the market.

Thanks. Drone with valves closed does concern me a bit. Let me know if you think it subsides a bit or you have any solutions for it.

It's very little but I'd suggest the resonated mid pipe would keep the drone out while giving similar sound but obviously can't say for sure. It's passed the wife test so that's good enough for me
The exhaust is still breaking in so I'm sure things will change.

Sharing some photos I snapped while getting the axleback installed at a friend's shop. Loving the sound and the way it looks. I went with the carbon tips for anyone wondering.

Something seems a bit off with the right inner tip? Looks like the brace between the two tips there was welded with it a bit lower than it should have been. Not sure though.

Yeah would need to hear from MAD regarding the tips being off-kilter there, that looks way off.

Sorry Y'all been busy with the holiday and a newborn so haven't had time to post. I think the pics can be misleading, I took another raw photo from the rear to show how they line up. I think the offset tip sizes may be playing tricks but lmk your thoughts. Either way, I still highly recommend MAD I've been talking with their customer service to make sure my units 100% up to my liking.

The far right tip does look like it got bent up a tiny bit possibly in shipping or somewhere along the line.

I sent you a few options so to remedy the problem
