AA DP @ Mid-Pipe Air Leak
Installed the Active Autowerke DP the other day and for those that have done this know there's a slit in the mid-pipe that allows for some expansion for the DP to slide into. It's not visible under normal circumstances while under the car since the clamp conceals it.
I had a hell of a time getting the OEM DP out as it was tightly wedged into the mid-pipe and had to use a screwdriver to slightly pry the slit apart a little to wiggle the DP out. I also think the AA DP does not extend fully past the slit in the mid-pipe, thus leaving a very small gap for air to leak. After install I started the car and crawled back under to feel for leaks and the DP to turbo felt good, but I could feel (and hear) air coming from the DP to mid-pipe. After the car warms-up for about 10-15 seconds and the idle drops a little, I no longer hear the air pump sound. I'm thinking about taking the car to my trusted muffler shop and having them do a proper weld. I know in the past with previous cars the muffler shop has told me they hate clamps as they will almost always leak. Anyone else weld your mid-pipe to your DP? I'm about to leave on a 2,500 mile road trip and may wait until I return just to make sure there's no CEL's before having anything welded. |

I just removed the OEM DP and it was a PIA. At first blush, seemed real easy with everything being easy access but didnt realize there was clip behind the 2 bolts on the DP bracket, that cost me time and effort.
The biggest hurdle tho is getting the DP to go in the midpipe as I cant get it to slide in. I try to align but fittment is way too tight. Almost sounds like you had then butted up and then just used bracket to hold together? |

I also had to use a floorjack to ever-so-slightly lift the midpipe through the bolt-hanger to get the nut started. Also, I didn’t know about the clip above the 2 nuts. I was telling my son about it, as he just installed the same DP on his Supra, and he scolded me for not watching YouTube. lol |

Have any other members experienced the air leak issue that XC3LLR8 had? I am having a local muffler shop install my AA DP tomorrow morning and I am debating between having them bolt it on or weld it. It's a very reputable shop with 4.9/5 reviews. I can definitely see the pros of not having it welded on if I ever want to remove it for whatever reason. Would the air leak be something that the shop notice/hear right away after the bolt-on? I was thinking of mentioning it to them when I drop it off so that they check for it.
