It's time for a little extra power on my E90 335i! I'm definitely going with a JB3, but I'm still undecided about which intake and exhaust to get. For exhausts, I'm leaning towards the RennArt, but I like the Harman Motive as well...and the UUC exhaust looks interesting for $999. For intakes, I'm thinking of just going with a BMS dual cone intake, until the definitive intake comes out (like maybe the AMS!). The Riss Racing and Ultimate Racing intakes just don't seem worth $450+ when a BMS is $139. Is the BMS intake enough for the JB3?

I'm open to suggestions. Thanks!

Just a note, Harman Motive is going out of business, so you might want to reconsider your exhaust options.

Yea i think the BMS intakes are worth the money, especially if you want to upgrade later. Exhaust will be dependent on your taste of sound. (Youtube)

I would go with the aFe Dual Cone Intake for your 335, we have this installed on our E92 335 and I am planning on doing it for my 135. I am very impressed with the level of quality and ease of installation, not to mention it produces a nice improvement in power and air flow without being too intrusive as far as install goes.

For the exhaust, I would also recommend the Active Autowerke 335 Exhaust which we have on our E92. I find this to be a perfect upgrade over stock in that it's noticeably deeper but is not overly obnoxious so as to be unfit for everyday use.

Go with a BMS dual cone intake .. 400+ dollars for the other intakes are ridiculous and show no power increase over the 100 dollar dual cone. They look nice though.

Exhaust, pick one you like. There is a sticky on top of this forum with videos for most/all of the exhausts made for this car. The gains are pretty minimal with an exhaust so it's pretty much subjective to you.

Thanks everyone!

How about some 3" Hi-Flo™ downpipes to really open up the exhaust?

How about product xyz that I just happen to be selling???

I think it is pretty clear that I am a vendor from my sig as well as the "supporting vendor" tag near my username

And downpipes will definitively improve his exhaust, regardless of which brand he goes with.

So either way, my statement stands

Just wondering, with the 335i engine.. after upgrading the exhaust and intake, I'm guessing you would surely need to upgrade the fuel computer to keep up right? Does the ECU piggy back do this?

the JB3 does for sure.

and btw, AR is right, DPs - especially catless - will help power alot more than exhaust.
...now the next question would be which DPs??

Definitively no question there!

Yep it sure does, the Active Autowerke Processor we offer has various maps that you can download based on the modifications you have done to the car. For instance, they have a map specifically for cars with exhaust, intake and downpipes installed to maximize the gains from the additional air flow.

We are running very deep discounts through next week on the Processor software so feel free to contact us for info on these specials.
