Not sure why you lost your mind but I was talking about the tips on the left side of his vehicle and the fact that they hit the outer edge of the exhaust cutout in the bumper and they are wrongly protruding from each pipe . I don't see anyone else's aftermarket exhaust options with 2 different diameter pipes but if that's their design , good for them . If that's their engineering idea to make it quieter , they could just weld it shut for superior quieting skills .

Why would anyone make it with one small pipe and one large pipe ?

It can't be an install issue because the left side sits way too far to the outside . You can't move the catback out more and not have the right side , that fits correctly , not stick out more than it should . You also can't switch the tips to make it fit correctly if the pipes are in fact 2 different sizes like you say . Sounds like it comes down to build quality on this .

i agree, when i had my guys put on the exhaust they tried to switch the left side pipes with the right side pipes incase they were packed up incorrectly by the manufacturer but it was still fucked. heading to the shop this thursday to get some pipes fabbed up to fix this issue

I'm sure the shop will fix everything and make it look right . The downfall is you have to spend a little extra money to fab up some new pipes . When it's all said and done , you will still be spending less than the cost of the actual Valvetronic exhaust so you still win on savings .

They made M40i exhaust and responded in the thread, I'm kinda surprised they haven't responded in here also.

Holy shit that is gorgeous. How's the build quality? Is it really that much lighter being titanium? Where did you buy it (what vendor in ali)? Can you post the link?


Please post pics of the install and if you can vids of its first time firing up.

Read your comments to them and they were on point, thanks for keeping them honest.

Saw their video and it still feels very deceptive. I'm curious to hear from the poster above about his impressions on built quality, clamp quality etc.

Stock comp exhaust is 88.5lbs, per BrockDM and this weighed in at 47lbs. Solid reduction. Build quality is pretty good, looks solid. Not top-tier, but that's expected. I just dropped the stock exhaust so it's underway. Probably take me most of the day, but I'll keep y'all updated

85.5lbs**

Thats a pretty significant savings tho. Cant wait to hear it 👍🏼

I like you, this is the people we need on these forums. Thanks for making those statements it was quite a fun read. I do feel bad for people who still doesn’t acknowledge that they’re paying 6 grand for an exhaust that is just metal pipes made in China.

Got the system installed Saturday, did some troubleshooting yesterday before the game, and have it narrowed down to two issues.

First, in efficient mode at idle I'm getting a tapping/ticking/puttering noise. Mostly from the passenger side muffler exit pipe. Doesn't sound like pipes rattling. Unsure if this is a defect in the muffler or installer error on my part. The noise lessens dramatically in S+. Going to go back and double check the clamps and make sure it's not leaking, although I'm not confident that's the issue.

Second, I've ordered a SST exhaust flap controller and here's why. The OEM controller is all over the place. It's not noticeable at stock exhaust levels, but it's painfully obvious with louder configurations. I've been out driving a few times since installation and it's been wildly erratic with how wide the valves are open. It's like it's got multiple personality disorder... so weird. Took the valve motor off yesterday and verified it's installed correctly.

Many were asking about the fitment, and overall, I'd say it's pretty good. It clears all components of the vehicle. The resonators seem to have shifted a bit since I installed and are sitting a bit closer than I'd prefer. Nothing is rattling yet, but made need to adjust a bit soon. The rear exit pipes/tips are a work in progress. The driver's side exit is currently sitting a bit further towards outside than the passenger's side. Adjustment up/down and between the two pipes on each side is easy, but this may prove slightly harder to remedy.

These are all just initial impressions and it's a bit of a work in progress. Relatively happy with the fitment, not happy with the sound yet. I've caught a few moments of a very nice, aggressive idle/WOT, which leads me to believe this system can be what I wanted it to be, but the stock valve controller seems to be actively working against me lol

Bit of a pathfinder mission I've embarked on, will continue to update as things progress.

I know yours is not the X3M system but did you use the system as it came or did you modify anything to make it work ?

Thanks for the follow up and pictures. Did you have the controller issue before hand? I wonder if you had it but the stock system did a good job of hiding it.

I'm curious why you think the OEM exhaust would "hide" this issue ? I would think he would have noticed with valves open even with the OEM setup .

No idea. I'm also wondering if the muffler is just needing a bit of a break-in period. The puttering/ticking noise coming from the exhaust at idle was more quiet this morning.

What wasn't quieter was the driver's side valve that was rattling like some metal bones when I turned it on this morning! Apparently with valves closed at idle at certain angles, the valve is loose enough to cause a bit of a racket. When I pushed on the exterior side of the valve (opposite the motor) it would stop. I rolled it forward and it went away. Pushed on it again and it started rattling. Put it in S+ and it stopped rattling and it had no play when I pushed on it under load. It's looking more and more like this is going to be a valves almost always open for me, which is fine. Only time I'd care is in the early morning.

Now I stink like exhaust and need a shower lol

[bad430benz]

Sounds like you are having the same exit piping issue .

It bolted right up with no issues.

Here is the install
