Not with MHD tune. It disables the check. Without it you will have a light show but it shouldn't matter. The sound wont be an issue at all on stock exhaust. They claim power increase just from the downpipes, but I didn't notice much. Just seems like the turbos spool up abit easier. If your not on MHD start with that. The difference from stock to 1+/2 is massive. Feels like a different car, and a true animal. If you just want power, your order of mods depends on how much you want but generally : stronger chargepipe and MHD 1/1+ bigger intercooler if you are on 1+ doing alot of pulls in hot weather, or tracking downpipes and MHD 2/2+ . You should be nearing 380-390hp at the wheels here. Then probably e85. I have downpipes and chargepipe installed, but am just back to running the standard MHD stage 1 tune now. I find it more than powerful for daily driving. I found I started wishing for a LSD and better suspension at stage 2, and decided to reign it in because it's a cruiser, not a track car.

I got VRSF ones delivered for under $400 nz from their website. Keep in mind that the mechanic fee will likely be upwards of $4-500 depending on how easy it is. They are c**ts to put on. I paid 8 hours labour to get mine installed with some sparkplugs . do it yourself if you can be bothered. I could never hear my rattly wastegates but as soon as the downpipes went on I could here them really loud on idle and cold start. The reason for running catless downpipes is so you can up the boost and run MHD stage 2 or higher. With a stock exhaust there is basically no difference to sound, definitely no pops and bangs or anything. It's just a slightly deeper sound with them on, but not louder with stock exhaust. You do hear the turbos spool abit louder with catless dp's. You can flash burble mod if you want pops and bangs - at your own risk. If all your after is pops and bangs you don't need downpipes, just flash the burble on aggressive. You'll likely mess your cats up pretty quick and some people argue it's terrible for your turbos. If it sounds like my view on the downpipes is negative, it's not, they are great bang for buck and really open up the car for tuning potential. I just don't think there is any point in them if your not going to run MHD 2/2+, or a custom tune. Putting that much boost through the car WILL show other weaknesses if there are any.

Seeing the only reason this car is 28k is because of the mileage, but the fact that it's been modded probably means it's been thrashed abit, and it's still 10 years old - and the mileage isn't so important, I can't see the justification in that price. I paid $13k for a 70,000km 2008 335i almost a year ago. Completely mint with all options. It would never have given me any issues if I hadn't had tuned it. BUT, as soon as you wind the boost up, thing's start to show their weakness. 30-70,000km is when things will fail under the higher pressure. TBH I just can't see how this car is worth more than 17-18k

"VERY Rapid car, some talent is required to drive" 🤣

How is it more exciting? In a straight line? I found my old 200 horsepower fwd honda more exciting than my 335i on MD stage 2! Steering feel, road feedback, noise, engagement etc. I don't see how a 335i can be labelled an exciting car unless you've completely revamped the suspension, the exhaust and added a LSD

I figured once they get a refund, they might still go about purchasing a 135i. Understandable if they can't even stand the thought of them any more though!

I literally went, last year, from a 2005 k20a euro r to a 335i. Once you get your car/car running, you will certainly enjoy the difference. I can't believe I used to think the euro r was fast. To be fair, it was much more engaging when on spirited drives. Nothing like a high reving na engine mated with manual. For everything else the 135/335i just has it beat.

What a dealer huh. Good luck mate. I hope you are ready to spend the cost of the car again on legal fees if this goes to court.

Looks like im becoming quite the regular on here... Last week the nipple thing that the coolant house running across the intercooler broke off, so I got it replaced. Mechanics flushed and replaced coolant at same time. Next day after testing my car out (I got downpipes installed too), I found coolant splatter around the expansion tank. The car is leaking coolant around the seam at the top. I will replace the tank my myself asap. After the car is warm, I can hear alot of noise from around that tank. I believe it is the coolant and air escaping, but I hope it's not boiling. I am hoping the mechanics either : a. put a little much in and it's just getting rid of the excess through the leaking seam b. didn't bleed it and theres air in there somewhere making it heat up too much I ran the bleed procedure today and will keep an eye on it. The coolant level itself hasn't noticeably lowered after a week of daily driving it and it sputtering out. I have to drive to fox glacier and back next week, is there any other steps I should take before I leave (apart from take spare coolant with me encase I need to top up) I pray it isn't a headgasket... the cars only done 75,000.

What a f**king headache XD I hope you still have something to drive while this gets resolved?

Yeh I understand what each tune requires, I was asking if it was safe to stay on stage 1/1+ with catless downpipes or if I needed to go stage 2. But seeing there is an option to choose catted/catless dp's on the stage 1 flash, I am guessing it is safe.

Im safe running stage 1 with vrsf downpipes right? Or do I need to go stage 2 so the tune knows I have pipes and so can adjust for the o2 readings correctly? I reflashed stage 1 with the pipes in, and made sure the catted downpipe box was unchecked, so I think im good, but doesn't harm to check.

Yup, that long thin one going across, but the actual break is the nipple that it sits over ont he large pipe going from the intercooler. So had to replace that whole piece. It's in now anyway with an oem replacement so hopefully it's good for a few km's. I had intercooler o-rings replaced two weeks ago and I am guessing it got cracked/damaged during the movement.

Update, downpipes in, ended up using auto authority (porsche specialists) because they are closer to my work. Took the guy 6 hours from start to finish including testing for leaks, road test etc. - $630 + GST If anyone else in CHCH wants them done, I would presume they would be faster next time. Pipes sound a little throatier, went to test them properly last night but noticed my temp rising higher than normal. Got a low coolant warning this morning, felt for leaks and one of the coolant hoses snaped right off in my fingers, right where it's connected to the drivers side of the intercooler hosing. Was incredibly brittle. Sprayed everywhere and burnt my hand a little. So it's back at autothority today, getting the part and coolant replaced. Also I can hear slight wastegate rattle now that I have the downpipes on........ feels like this is going to be the start of never ending repairs XD Hopefully not.

Same kit. Apparently has a replaceable cartridge for the sealant although im not sure where to acquire one.
