Sorry guys but I can't help laughing at the replies? made my day

I'm wanting to bring my 335i to a garage in Wellington to get the catless downpipes installed.

Trying to shave a lil bit on labour here so would be great if I could bring it to someone who's got experience on installing them.

Wanting to buy a JB4 my 2007 335i

Hi Tony,

I am from Wellington as well, look at the http://bimmersport.co.nz/forum/26-wellington/ for Wellington based meets.  There is a Cars and Coffee this Sunday.

I also do landscape photos every now and then, sometimes include our old cars on the photo.  Hope to see you around.

Yea man see you around. I'm very keen on doing meets and track days.

Hmm I'd say that's either catless or something is done to the exhaust, if you can't see any signs of the PE mod. That doesn't sound like a PE mod/exhaust to me so I'd lean towards it being catless. 

"So on MHD the option is OEM/Catted DPs, and I have always had it checked. Did you mean that I should uncheck it and see what happens?"

With it checked it should still trigger the codes just like with stock. You should have a check engine light and some fault code(s) about emissions. If you're not getting this then... your cats are still there and working. 

Also when you checked the Oxygen Sensor and Oxygen Sensor Heater, was it only after flashing a tune? Flashing a map resets them, you need to drive for a while, maybe about 30 mins, before they'll show the status. 

 

Edit:

One more.. are the cars you've been comparing against sedans? The sedans actually have an extra resonator in the exhaust that makes it quieter than the coupe.

So this is what I get from MHD after driving for about a week and 20km daily.

There should also be a code and the associated check engine light, assuming you haven't enabled the MHD flash setting that clears it. If you have, re-flash the map without the catless option or flash back to stock, and see if it comes up after driving a bit. 

But I'd say that's a good indicator it's catless. Catless downpipes make a very obvious difference to the sound, it's about twice as loud as stock. 

For the sound, it's also possible the 'PE mod' has been done. Look at the top and bottom of the mufflers to see if they've been opened up before, you'd see welds from it being sealed back up. Google the PE mod to see what to look for. 

I've got a few clips here if they tell anything, my burble aggressiveness setting is on hard and it sounds way louder than my mates 335i with the same settings.

Hey Tony - welcome to the family.

Nice looking 335 you have there - those aren't the standard Msport wheels?

I see your photo was taken at Ormiston college - but you're based in Wellington?

Thanks man! Those wheels I believe was optioned back then.

Those photos were taken 2 weeks ago when I drove up to Auckland to meet up my mate who just bought a M4 CS.

Hi there I've recently joined the forum! I'm Wellington based and very keen on meeting with you guys.

I do landscape and car photography as a hobby, if you like my photography style and would like a set of photos for cheap then feel free to hit me up!

I own a 2007 335i M Sport, changed intercooler, charge pipe and bov, currently running on Stage 1+.

Hi guys, I own a 2007 335i and I'm wondering if there's way to figure out whether the downpipes has already been decatted other than taking it off and check.

Reason for that is because when I checked underneath my car all the pipes look to be stock but it sounds louder than other 335s I know with the same MHD tune settings. And in MHD under both Oxygen Sensor and Oxygen Sensor Heater are incomplete. I've owned the car for a year and it's always been showing the same info.
