Yeah, it’s a lot raspier tone and the pops/bangs are much more distinct.

It was just under $1000 for everything. I think the exhaust was around 700 and 300 for shipping.

Yep for sure not a problem. I hope these help. The first video is completely stock. Verse downpipe and aftermarket exhaust. second video was a poorly made install video, but maybe it’ll offer a few pointers to people.

The downpipe did throw a code initially. It took a few tries to get it right. I got CEL with no spacer so I put on one similar to the fabspeed minicat. That threw a new CEL so I swapped for a $10 spacer from Amazon. That worked and no more codes. I didn’t think the downpipe made much of a...

I swapped the stock exhaust today and it turned out pretty nice. I’m too cheap to spend thousands on stuff I can get for hundreds. So I ordered an exhaust from the AliExpress app. It was $650ish and just under $1000 shipped. It took a little over two weeks to arrive from China to California It’s...

On another note, can anyone advise on sending logs to burger? I’m plugged into the OBD and connected to Bluetooth. I’ve stored three logs so far and I can’t seem to email them to myself. I’ve tried multiple times to two different emails and they never come through to my inbox or spam. I’m using...

Just want to give another perspective on the install. I’m not very mechanically inclined; other than changing the oil or brake pads and basic bolt on mods. That being said. I did the install in my garage on ramps. It took about 2 hours and a lot of that time was spent tracking down the right...

What code were you getting with the downpipe? I went with a 200cell down pipe with fabspeed “minicat” and I’m getting a cel from time to time.

If it does come back on, and you have to take it in, I would suggest printing up the Mercedes TSB on the issue and make sure the advisor gets it to the service tech. Mine sat for almost two weeks before they came up with a diagnosis. My part was ordered and received within two weeks. I had the...

Sorry about that, yeah it’s the green with blue stripe. My eyes are horrible. I couldn’t see the blue until I zoomed in on the pic.

It’s a little louder, but not what I was hoping for. It ran fine for the first 50 miles or so, but I got a CEL yesterday for O2 sensor bank 1. I cleared it and installed a “minicat” from fabspeed. After a short test drive the permanent code deleted so hopefully it’s good. I might swap back to...

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...
