Before and after Yes it is. I couldn’t get the video to load on the forum.

Got the down pipe installed today. That was a pain in the ass, but after 4 hours I finally got it. I am far from a mechanic so most of the time was spent searching for the right tools and a ton of time was spent trying to get enough room to maneuver the stock down pipe out of the engine bay...

I have a similar timeline. It’s been down for about 30 days in total after 3trips to service. The first trips to the dealer they claimed they couldn’t reproduce the CEL code. They did say the supply chain has slowed down lately in parts. Mine took a week longer than anticipated by Lotus. Did...

got the car back yesterday. No CEL after 60 miles of driving, but they did not follow the TSB per Mercedes. They only flushed one time and only replaced one thermostat. We shall see…. In the mean time I’m gonna swap out the down pipe and install the JB4 tomorrow. (Hopefully)

Yup. 2.0 is the same. That’s where I ran my power cable for the amp. One person in the engine bay and one in the cabin with a coat hanger. Was fairly easy to grab onto it and pull it through.

Yes, the mid pipe I received looks like the photo on their website. And yup, it’s pointless. I ordered it prior to getting under the car to see the 2.0 doesn’t have a “third” cat in the mid pipe. I’m hoping the downpipe opens up the sound a good bit, but we’ll see. I did Catless downpipes with...

It’s still at the dealership. Two weeks so far.

Dropped off at Lotus last Monday. Got an update today; they are starting with swapping the thermostat which should be here by the end of this week.

What dealer are you using? Mine is getting dropped off this morning. I’ll see what they say.

Just in case anyone is looking for info to give the dealer to direct them in the right direction; Here is a TSB from Mercedes addressing the concern in the M139. It’sTSB LI20.10-P-076206...

Well, I gotta delay the install awhile. My CEL came back in for the aux thermostat stuck open. It’s been to the dealer twice for it and both times they said nothings wrong.

I’m fixin to give the install on my i4 a try this weekend. Any tips or pointers?

I didn’t install it. I offered to ship it back to them, but they haven’t responded. I have since learned it’s a useless “upgrade” for the 2.0 i4. There is no third cat in the mid pipe on the 2.0. I’m guessing that’s a big reason. Why no other companies offer one for the four-cylinder. I did just...

Well, I just got off the phone with the dealership. They said the thermostat code did not show up on their end. However, there were two new codes. Apparently the aftermarket air filter and aftermarket audio I installed made the ECU go haywire and that was probably the cause for everything. They...

Dropped mine off yesterday for a fix. I shared that video with the service department at Lotus. Hopefully they will actually watch it. They said it should be ready by Monday. I’ll let y’all know the outcome.

It might be, but I don’t think I’ll find out until they replace the thermostat and see if the problem comes back. I’m hoping they do a flush anyway just in case. I took it in for the same issue a few weeks ago, but I had already cleared the code. They said everything looked fine besides needing...

Did Galpin give you a loaner while the car was down? I’m taking mine in on Friday. Thermostat stuck open issue they’ve been having popped back up.

CEL came back this weekend. I’m taking it back to Lotus on Friday. So far it’s come on 4 times from 100 miles to current 550 miles. Cleared the first 3 and left this last one. I’ll let y'all know what the results are.

Hope this offers some helpful advice…So I spent several hours searching around forum posts with suggestions for polarities before installing my after market speakers and amps. I found testing each speaker individually was the best choice because not every post is accurate. Especially with the...

On its way!!

Just want to give my personal experience although it may not be their normal practice. Long story short; ordered Catless mid pipe from phoenyx on April 21st w/ posted 5-7 business shipping. Fast forward to today, May 14th and still no mid pipe. I’ve been in communication with them requesting...

I’m a visual learner. Who wants to post an install video for the i4?

I’m a rookie with car audio installs so this might be a useless response, but… Once I installed the sub in my Hummer I could definitely notice a difference in the bass when I crack the windows open opposed to having them closed. It seems to have more bass with the windows open. I think it might...

Boom! Can’t wait.

Kaz went through a much better verification process than me. I just put my ear next to the rear speaker while giving it gas; before and after cutting the wire. Sound was there before and no sound after. Both times the radio was off.

Here’s a better view of the wire.

So I looked backed through my photos and realized the video I thought I was recording wasn’t actually recording so all I have is the initial portion of taking the trim off. I tried to screen shot the best I could with a yellow arrow pointing to the wire bundle. I’ll take the trim off and get a...

Got distracted with errands today but had enough time to fix the engine noise and wire the sub. It sounds a million times better with just the sub. I’m gonna tackle the tweeters tomorrow morning. I found the thread with the wire colors.
