Product Description


We are proud to introduce our VRSF 3.5" catless downpipe for your N55 135i & 335i/xi. Thie 3.5" downpipe is THE best bang for the buck mod available. By eliminating the restrictive catalytic converter in the factory downpipe, back pressure is reduced significantly which results in faster spool, an increase in power & a more aggressive exhaust note.

Our catless downpipe feature a full 3.5" stainless steel design and are hand crafted from SS304 grade stainless steel and include a lifetime warranty as well as our "No Hassle" satisfaction guarantee (includes fitment). Grade 12 installation hardware and high quality steel gaskets are included with purchase.

Note: Our N55 downpipe now comes ceramic coated free of charge. We use Cerakote's best thermal barrier coating which helps keep the hot air inside the exhaust and out of the engine bay which decreases overall intake air temps along with engine and transmission oil temps.

I got the downpipe in the mail Friday and installed it yesterday. I am very happy with the pipe itself installation was a breeze and everything fit like it should. Also it sounds great. Awesome product. I also installed jb4 today and the two made a good combo. (Posted on 3/1/16)
Super happy with the final resultReview by chronopete

I installed the 7" VRSF FMIC myself (lots of trimming required to fit, used a dremel) and I had the VRSF DP professionally installed (it's a pain, gotta remove the engine mounts on a X drive model and secure the engine so it doesn't drop to the floor) last summer and I'm super happy with the final result.

I'm happy with the sound levelsReview by GoodMoodley
Overall Rating
I just installed a VRSF DP on my N55. I have stock exhaust. On cold start up it is quite loud but this only lasts for a about 20 seconds.

Once the engine warms up a bit the sound evens out. It is a little bit louder than stock when driving normally with mild throttle inputs. When you step on it it sounds great. I even get pops and burbles that were not present before. I was considering getting exhaust as well and am glad I didn't. I'm happy with the sound levels I have now. (Posted on 2/4/16)

This is the way to go, and I couldn't be happier.Review by ryanakata

The next day this arrived. I headed to my parents house roughly 2 hours north of me where most of my tools are still located. Got the car up in the air, and began snatching the old one out. The old one is huge and heavy, I do not look forward to the day I have to put it back in. My advice to anyone installing a downpipe is get some EXTREMELY long needle nose pliers to help close the clamp onto the downpipe and turbo. Also once the clamp is seated it is nearly impossible to rotate the downpipe. I am going to attempt to rotate mine this weekend as it has my exhaust in the rear slightly out of alignment. I would recommend buying on that has a bracket on it for the transmission brace, but I couldn't justify the extra $$$ just for that feature. Also when you finish this job your hands will look like you stuck them in a meat grinder.

So I get everything back together, and the first start, CANFlap Open, and Whooaaaaaa it's loud. My parent's come outside to see if anything is wrong but then it idles down and sounds just fine. I take it for a drive and am in love with the sound. You can hear the turbo spooling in normal driving. I get the car warmed up, switch to Map2, head out near the airport. This thing is a beast now, I had to use the DTC button to prevent the car from interfering with the throttle. It slams you into the seat, and sounds like an exotic after 4k RPM. Combined with the JB4, this is the way to go, and I couldn't be happier. (Posted on 7/2/14)
Quality product it fit first try!Review by ZeroSix

So I decided to order a VRSF Downpipe while waiting for their catback to release. Plus its still at their discounted rate so I said fuck it and went for it. I got it within 5 days over the weekend and was looking for a place to install it. Muffler shops didn't do me much good since California's emissions laws are so strict. I called 3 body shops. One quoted me $300 another $290 and EAS quoted $190. Made an appointment at EAS 2 weeks in advance and looked for other options. A buddy of mine had a small garage where a few guys do some work on their drift cars. $100 installed still found it a little pricey but the labor it requires to get to the Downpipe isn't the easiest. Took about 3-4 hours and wow am I impressed. Note I have stock mufflers still

So cold start is loud. Once warmed up it goes to a quiet rumble a little louder than stock. Regular civilized driving there isn't much sound difference either. It's very nice for cruising. The smell is similar to a lawn mower it's not awful but for sure noticeable. Now when you push the to my ears! It sounds amazing. You can hear everything from the intake pulling in air to the turbos spooling and the exhaust roaring behind you it's beautiful! I'm debating on keeping it how it is now! The turbo spools a lot quicker, response is improved. And my stock run flats don't hold traction (gotta change them ASAP) oh man those pops and crackles are crazy! I've scared a few people on the side walk.

I really have nothing negative to say about this Downpipe it was worth it entirely. Quality product it fit first try. I have a JB4 so it clears the code for me so I can't tell you how long it took my CEL to turn on. I'll try to upload some videos for you all! If you have any questions or whatever feel free to ask!

Fitment was perfect!Review by Jgabucc1
Overall Rating
013 335xi PPK + JB4 set to map 5, high flow filter, and now a VRSF downpipe.

I have read several reviews on this forum none of which really convinced me or drove me from an emotional standpoint to get this done due to issues with CEL light, and installation hassle of getting this installed on a XI.

To keep this brief and to the point, anyone who is on the fence about swapping out the stock downpipe DONT BE! This is of course your currently running a JB4 or other tune. The car should of came like this out of the factory. It's a whole new animal and has really added to the fun factor which simply wasn't there before. Acceleration in all gears and RPMs has increased tremendously, add that to the fact the sound of the turbo spooling, big increase in burble and pops heard, I almost want to say I look forward to getting in the car and going for a drive.

Fitment was perfect and the unit aligned, with a little play of the exhaust, perfectly. I'm very very happy with my choice and regret not having this done sooner. No idle issues to talk about. So far after two days I haven't smelled anything differently than when the catted pipe was on the car. (Posted on 7/2/14)
