I am considering doing down pipes on my G82. Really don't want to deal with CEL and I see that Active Autowerke is the only one that guarantees no CEL. Their GESI catted DP's are 400. I see other companies have 200 and 300. Really want to add more sound to my current setup (Active Autowerke non resonated single midpipe and Valvetronic axle back with Dahler valve controller). Don't want to spend over $2000 and be disappointed with these down pipes. Any suggestions? Any body have the AA down pipes that can shed some light on how they sound? Thanks for any help.

Much cheaper option would of course be 200CELL and o2 spacers

I hear mixed reviews though on CEL, common consensus is no CEL with that setup installed correctly but some cases of still getting a light.

With a $1500ish price difference it’s definitely something to consider

Daily Driven did a full video review on their GESI pipes though and should give some good insight

Either way good luck!

AA's stuff is very high quality and you will not get a CEL with their catted downpipes. I have had their downpipes on my other cars for thousands of miles with no CEL. I can't speak to sound differences for G80 though. There was only a mild increase in sound on my other cars. Biggest difference was at startup, mainly.

Do you have to worry about passing smog in NJ?

You get a CEL “P013x - 02 Sensor Delayed
Response” . I’m going from catted to catless DP cause of that . The car sounds great tho.

I’d recommend $500 catless Dp with spacers .

Why are you going catless DP with spacers? You wont get the CEL you are talking about? I really don't want any CEL. I also don't want to spend over $2000 on AA DP's if I'm not going to get that much of increased sound.

I don’t mind the CEL, but unfortunately, remote start doesn’t work if the CEL is on. The CEL comes and goes; approximately 80% of the time, it’s on.

Currently, I have MAD’s catted DP with Daddy’s catted spacers. However, I just received a catless Fatboy DP. I’m going that route with my Daddy spacers. The spacers work 100% with the catless DP.

I really don’t see the point of spending over 1k on the DP itself. Save yourself some money, go catless with Daddy’s spacers, and you’ll be fine.

Thanks for the information. Just wanna make sure I understand this correctly. So the O2 spacers with catted DP's I'll get the CEL 80% of the time. If I go catless with the O2 spacers no CEL? I'll get the smell with the catless though right?

Once someone finds the right combo of spacer to go with the catted it should work just as well.

I have GESI pipes on my F80 no compromises and no smell.

They work great no doubt. I think people are struggling with the cost vs performance benefit compared to staying with the factory downpipes.

So is this confirmed now?

On a car that's nearly 100k, 2-3k is little money to spend for peace of mind IMO, if you really want upgraded downpipes

I was referring more to the Dollar to Hp cost which is undeniably high. Like I said they work as advertised and it's a excellent product however, they flow closer to the stock downpipes than they do a catless setup which can make it a hard pill to swallow for most especially for those in the quest for horsepower.

Yeah if you're going on a quest for horsepower you're likely tuning and can therefore tune out the CEL haha...at which point it doesn't matter which way you go. I don't like catless personally because I can't stand the smell but even then a 200 cell cat is good enough.

I used this on my M4 and ultimately had to uninstall it due to a considerable increase in exhaust noise. If you're concerned about the system not providing enough sound, I can assure you it's unlikely to disappoint.

do you think the awe switchpath with non res midpipes and the gesi downpipes will be too loud?

Which midpipe?

I understand your dilemma and that's why we offer the GESI catted DP's. No smell, improved sound and performance but most of all not having to remove them every time you need to pass smog. The labor alone on and off each time makes up the difference. Buy the other DP's and run the risk whether the spacer works or not, and if you will pass smog.

The GESI DP's are just a bit louder than stock, catless is extremely loud, sounds very unrefined for a BMW, 200 cel not sure as never heard them in person, but can only assume they are between catless and GESI. Adding MP and rear exhaust will also get louder.

IMHO, putting that $$ towards unlocking/flash tune will yield much more power and better driving experience than what downpipes-only can provide.

Here's an update: So I pulled the trigger on a set of Evolution Racewerks catted down pipes. Had them installed last week along with just spacers. Crossing my fingers no CEL yet. As far as sound goes: HOLY S**T!!!! Sounds AMAZING!!! Cold start is loud but after the warm up isn't too crazy. Car on normal driving sounds great. Enough pops and burbles when you let off the gas which was decreased after I added the Valvetronic axle back to my AA single non resonated mid pipe. When you get on it is sounds like an ANIMAL!!! Absolutely love this set up now. Thanks for all your help and replies to this thread. It's really appreciated!!!
