Two questions
1. The valve has two positions from what I’m hearing. One of the positions is for sport and sport plus. The other is for comfort and eco. Is this correct? I only hear the actuator make the sound when I swift from comfort/eco to sport/sport plus. Changing from sport to sport plus doesn’t make that actuator sound.

2. Is there a way to visually see the flap position? With the stock exhaust i could see the position. With this i wasn’t able to.

On a side note, fitment was perfect. Installer had no issues. I smelled a burning smell inside the car for the first 10 minutes but that went away. Inspected the rear and nothings burning.

10/10. This thing roars in sport mode. I might put it in sport mode and unplug the fuse to keep it like this in all modes but i want to drive it around with both options first and see how it is.

Glad you are liking it!

1. That correct there is two valve positions sport and sport plug should be the same.

2. Not very easily since its around the bend but you can verify the position from the motor on top. Just note the position when the vehicle is off and it should be 90 deg in sport. Honestly if you are hearing the difference its working.

I order my MAD exhaust through ECS, supposedly your largest supplier. It said on their website the exhaust was available and ready to ship within 3 business days, very unhappy to say that that was April 16th and it is now JULY 21st WITH NO confirmation if and when ill ever get my exhaust. Is there anyway someone can help

Sorry to hear about the situation. I can tell you we have shipped all of our exhaust orders out to ecs already and based on tracking the last one we shipped was delivered today. Unfortunately we do not get purchaser info from them when they order but they should be shipping them out to you very soon if they haven't already.

If you don't get a tracking within 1-2 days from them please Pm me with your info.

Typical procedure thru ECS unfortunately Just about every time I order from them everything is in stock ready to ship immediately UNTIL you pay for it & place the order - then the item is not in stock & delivery pushed out wks if not months.

Last order I placed with them on June 3 was for 2 items, 1 I needed immediately, the other just for later maintenance. Both in stock b4 I paid, then all of a sudden, the item I don't need is delayed months to shipping sometime in August & they won't ship partial orders, so I cancelled the entire order

Won't be using them for anything in the future other than looking up P/N's to see pics of items

Weird coincidence, but my exhaust shipped this afternoon. Not sure why or what the hold up was, I’m just happy that after 3 1/2 months of waiting I’ll have it soon.

Most of it was us. We were delayed on getting our exhausts. My apologies.


Glad you finally got it though. Well worth the wait once you hear it

Does this exhaust require wiring thru the truck into the power outlet for the valves?

No, we use the original valve controller and harness. We do provide a plug and play Y extension harness to control our second valve . This does not involve any power or going through the trunk.

Bought this exhaust and i’m loving it. However, recently i’ve been experiencing some drone in the cabin.. Is there a solution for this?

What do you mean by recently? Like it wasn't there before and now it is?

[OPCanadian]

Yes - Sport plus mode, low rpms, feels like a vibration in the cabin under my shifter. Called the shop that installed it but they stand by their work (and honestly they’re well known for their work). Told me to get in contact with the manufacturer because it’s “drone”. And also to see if there’s any solution in car groups/threads with my car.

Sounds like something shifted and may be touching the heat shield or body of the vehicle. Drone doesn't just start out of nowhere like that and it's more of as bass sound at a specific rpm range and not a metal to metal vibration.

I would attempt to get the car on a lift to check any of the pipes or clamps bolts so see if they are making contact anywhere.

[OPCanadian]

You know.. I figured that too but don’t have a lift to see. I’ll call around to see if someone can take a look.
