BMW introduced a new valvetronic, single turbo version of its direct-injection engine for the F-Chassis models beginning in 2012. The Active Autowerke N55 downpipe for the M235i, 335i, 435i and M2 helps unleash some of the potential that is restricted by the OEM downpipe. 

Turbochargers are powered by spent exhaust gases created during the combustion process. The quicker these gases are evacuated, the better. Unfortunately, the factory down pipe in the N55 is quite restrictive, which results in slower exhaust gases and slower turbo spool.

The Active Autowerke F-Chassis N55 Signature down pipe utilizes 3.5” diameter stainless steel piping in order to provide more power, quicker spool, and extreme durability.  This variant includes a 4.5" high flow GESI catalytic converter that will NOT produce a CEL! 

The GESi® G-Sport Ultra High Output Catalytic Converter features full 304 stainless steel construction, including the substrate. GESi® UHO-Series Catalytic Converters are EPA certified in 49 states and fully OBD2 compliant. GESi® proprietary precious metal loading technology ensures greatly reduced emissions, eliminating most "Check Engine Lights". These high flow catalytic converters outperform stock converters and provide a reliable solution to the most common catalytic converter problems.

The GESi® UHO-Series Catalytic Converters are rated for engines putting out between 500 and 850 horsepower while maintaining a high flow capacity. The reduced back-pressure from this high flow catalytic converter will allow you to maximize your engines horsepower without the harmful emissions. Say goodbye to Check Engine Lights and failed emissions tests!

Please Note: These catalytic converters are not legal for use on vehicles registered in the state of California as a result of California Vehicle Code Section 27156 and 38391.

Finally a Cleanser That Doesn’t Trigger My Breakouts
Size: 13.52 Fl Oz (Pack of 1), Style: 13.52 Fl Oz (Bottle)
I've been using this facewash twice a day for about a month now and out of all the cleansers I've tried this is definitely one of the few that have not made my acne worse. Usually my skin reacts within a week or two of trying new products but with this product it remained calm while still providing assistance for excess oil and little breakouts on my face. After cleansing with this product, it leaves my skin feeling clean but without that "overdried" feeling which is something that very rarely happens for me. The texture of the product is a thin gel that foams easily after using only a small amount, and it will rinse off completely and leave no residue behind when you're done using it. The product has no noticeable scent and feels extremely gentle even on days when my skin is more irritated or sensitive. The price of this product is slightly higher than some of the other basic drugstore cleansers, but the amount of time I have been able to use this product has been remarkable. If you're someone who wears heavy makeup on a daily basis, you may think that this product is not strong enough or you may feel like it's too gentle; however, it has proven to be a reliable and low-maintenance product for anyone with acne prone/sensitive skin types.

Gentle, Effective Cleanser That Leaves Skin Feeling Clean Without Drying
Size: 13.52 Fl Oz (Pack of 1), Style: 13.52 Fl Oz (Bottle)
I’ve been using the La Roche-Posay Toleriane Purifying Foaming Facial Cleanser for a bit now, and it’s been a really solid addition to my routine. The cleanser has a light, foaming texture that spreads easily and does a great job removing dirt and oil without being harsh. It leaves my skin feeling clean and refreshed, but not tight or overly dry, which is something I’ve struggled with using other face washes. I also appreciate that it’s gentle enough for sensitive skin. There’s no strong fragrance, and it hasn’t caused any irritation or breakouts. It feels like a good balance between being effective and still mild enough for daily use. The bottle is simple and easy to use, and a little goes a long way, so it should last a while.

Gentle, Effective Cleanser With Great Value Refills
Size: 13.52 Fl Oz (Pack of 1), Style: 13.52 Fl Oz (Refill)
Very reliable cleanser with clean formula and refill option. Fragrance-free, and doesn't irritate my skin. Excellent for daily use. The refill bag is a bit hard to navigate though, kind of floppy to pour from, and the cap broke of for me the first time.

Good Option for Sensitive Skin.
Size: 13.52 Fl Oz (Pack of 1), Style: 13.52 Fl Oz (Bottle), Size: 13.52 Fl Oz (Pack of 1), Style: 13.52 Fl Oz (Bottle)
I've been using this foaming facial cleanser for a few months and overall, I've had a good experience with it so far. I usually use it at night, and I start by removing my makeup with micellar water, then use this cleanser in the shower, followed by moisturizer. One thing I will say is that even though my skin tends to lean oily, this cleanser does leave a bit of a tight, slightly dry feeling on my skin after washing. I wouldn't really describe it as super moisturizing, but it's not a dealbreaker for me since I always follow up with moisturizer and it fixes that feeling right away. It also hasn't caused any irritation or breakouts for me, which is a big plus since I do have sensitive skin. It definitely feels non-greasy and very lightweight. The texture comes out as a gel, but it foams up really easily once you start using it. I also don't notice much fragrance in it, which makes it a good option for sensitive skin overall. Overall, I'd say it's a good product to try out. Just be aware that it can feel a little drying afterward!

Good quality product and value for the money
Size: 13.52 Fl Oz (Pack of 1), Style: 13.52 Fl Oz (Bottle)
I girl loves this product so much that I always buy one before the one been used runs out. Aside from all the vitamins and minerals included in this formula, one can tell how good the product is by just using for a short period of time. It has never irritated my skin nor my girl’s. The texture is perfect “ not to runny/ not to lose. The container is mostly a value pack, so it is not very portable, but at the end I prefect a big size to make up my value for the money. I recommend the product and will continue buying it.
