Just bought an MPE exhaust and need help

[BoostinLI]

Just bought an MPE, for my M4 that came with the stock exhaust. It appears I need flanges to make the exhaust connect, but I dont know where to find it. Can anyone guide me on where to make the purchase? Can those parts be bought from a dealer not the whole midpipe? Thank you.

Did you only get the muffler? You need the midpipe as well

Yeah just the muffler. Wish I could just buy the flanges and just weld the parts

Anyone have part numbers for the flanges?

Not an easy task my friend. Many people have bought the muffler and have given up trying to make it work. You need the MPE midpipe. I was informed by a member on here that you can buy it but it turns out to be just as expensive as buying the full exhaust. Do a quick forum search.

In addition. Whoever sold you the muffler knew that you would need the midpipe.They just didn't care and only wanted your money.

Fortunately I have a shop around that can get it done, but for a little more than I want to pay. The other option is to cut the exhaust but not to excited about that. The seller was just selling the muffler, had nothing to do with him.

OP, are you considering only having it in passive/open mode? Or is this shop going to put valves on and weld the actuator brackets for you as well? Because if you want the full MPE experience, I can see this adding up very quickly. In my opinion, passive/open mode would get annoying, especially on cold start. If you need to source the valves, I can get you in touch with someone who can get them for you, but the shop would still need to custom fab the brackets for the actuators to sit on.

Thanks for the reply. I wasn't aware, the stock actuator doesn't work on the MPE box as well? Great 😑. I appreciate you offering your resources. I'm going to give them a call today and get a little more information. Generally speaking, I prefer my exhaust fully open all the time as I have it that way right now with downpipes,midpipes and have the actuators disconnected fully opened with cold start off. So i "may" be okay, but I still want that functionality if needed. I paid pretty low price on the muffler, so hopefully it still remains a deal once this is all over lol

If I'm not mistaken, the actuators do work. But the valves and mounts that the actuators sit on are on the mid section of the MPE, which you don't have. So if you need the actual valves in order to transfer your stock actuators to, I can help you get them if you decide to keep the active functionality. But you'll still need the fabricator to make the bracket to hold the actuator in place to actually operate the valves.
