We are proud to introduce our VRSF 3" catless downpipes for the N54 E90 & E92 335xi. These 3" downpipes are THE best bang for the buck mod available, with gains ranging from 25-30hp when tuned. By eliminating the restrictive catalytic converters in the factory downpipes, backpressure is reduced significantly which results in faster spool, an increase in power & a more aggressive exhaust note.
Our 3" downpipes are hand crafted from SS304 stainless steel and include a lifetime warranty & our "No Hassle" satisfaction guarantee. Grade 12 installation hardware and gaskets are included with purchase.
VRSF 3" N54 335xi Catless Downpipes:
- Made from mandrel bent, tig welded 3" Stainless Steel.
- Smooth radius bends to decrease turbulence and increase flow.
- CNC SS304 Stainless Steel Flanges.
- Gains from 25-30hp with tune.
- Gaskets & high quality grade 12 mounting hardware included.
- VRSF Lifetime Warranty.
NOTE: We've recently upgraded the mounting hardware on all our DP kits to grade 12 nuts and bolts. This hardware is a significant upgrade from our original grade 8 bolts at no additional cost.
Application: 2007-2011 BMW 335XI
Model Number: N54EX125

- What a difference a day makes!Review by Welterweight
- Highly noticable sound and power increaseReview by Sandro
I drive a 2009 BMW 335xi purchased these downpipes because of the great reviews I've read and let me tell you that they do not disappoint.
The sound (exhaust & turbo spool) and power increase were very noticeable and enjoyable, especially when going WOT.
The installation, however, was rough. This was probably my own fault for not doing enough research for installation on the "xdrive" model, but it took my friend and I about 9 hours to install. The biggest problem was that the xdrive BMW's have an extra support brace (welded in place) located right below the downpipes, making the removal of the existing downpipes impossible (without cutting anything). Thus we found that the only way to rightfully install the new downpipes was to drop the sub frame in order to make enough room to slide the existing downpipes past the dreadful support brace (this decision was made about 4 hours into the installation process after realizing what we had gotten ourselves into). One way or another we managed to successfully install the downpipes and they have been glorious to drive with.
I drive my BMW for 2 hours everyday - roughly 200km per day - and have had these installed for about 2 months and have had no problems, only joy.
As a conclusion I would recommend these downpipes to any 335i owner, the sound and power gains (especially with my newly installed JB4 tuner) and incredible; just beware of the work ahead of you if you have an xdrive model. (Posted on 7/18/14)

- Finally a quality company that sells quality products without the "BMW tax."Review by psmitty95
When I received the pipes I looked over the welds and they seemed very nice especially considering these were a test fit set, not a production set. The FMIC also looked very well constructed and came with everything needed to install.
After getting the car back today I did a few pulls on the way home and definitely noticed a difference. Boost was building up much faster than it did before and the car was pulling much harder up top. It was also nice to be able to do repeated back to back pulls without the car heatsoaking. The DP's also added a good amount of sound.
I was actually surprised at how much of a difference they made to the exhaust note since I have an E90 with secondary cats and resonators. They also made the turbo's much more audible then they were before and I can now hear them spool up even during normal driving.
