if it's good enough for Honda racing...... Looks and preforms like i expected Awesome!

Short-term review: I've had this on my '25 FL5 for about 300km now. Since I haven't used other downpipes before, I can't compare it to the competition, but I'm happy with the quality and fitment so far.

Install was very straight forward. Only thing you really have to worry about is snapping studs off the hot side of turbo. Just use lots of PB Blaster, worked for me, no broken studs.

For some reason directions said to make the heat shield holes bigger, wasn't the case in my situation, the oem heatshield bolted right on to the downpipe, so that was a nice surprise.

I've mated mine with an RV6 front pipe and HKS Hi-Power exhaust. While finding a decent sound profile for this engine is notoriously difficult and highly subjective, I’m really impressed with how this combination turned out.

As for power, no idea, have not had it dynoed.

I did encounter the infamous P0139 CEL. Even though some have stated they never experienced a CEL, I was pretty skeptical and figured I would get one, and I did. No surprise here for me. I am tuned, so that was easy to resolve. Took about 200 kms for the code to pop up.

Attached a few photos.

I always use these springs on all my vehicles, and as always they don’t disappoint

Install was easy and alot thicker than OEM, just finished a track day at Ridge, Max coolant temp of ~221°F, definitely helps with temps!

The car is running cooler now. I haven’t seen it go over 180°F while driving. I’m also running the Acuity reverse coolant hose with this plate.

I’ve been running Cobb now for over 500 miles. I pretty much don’t really notice it, only time there’s nvh is with AC on during idle. Even that has continued to improve with more mileage. My friend test drove cobbs test car at their HQ, with 10k miles in their RMM already. It’s smooth and don’t notice it with AC on.
I think the split duro design helps and also the spoke design helps with heat reduction, which I think leads to more consistent performance. (So the inserts don’t soften up)

Wheel hop is reduced and car feels more connected. Able to put the power down better.

Ever since I put this on I've been driving with my volume off. The sound this intake produces is like music to my ears. I went for this mod purely for the auditory experience and if thats what you're chasing, then click that add to cart button right now. Love it.

I love ordering my parts thru unity performance! They respond quickly when you need help and my orders came quickly

Easy install

These covers are perfect for the Type R seats! They protect the fabric and not too slippery when driving on track. Would buy again.

The HVI was out of stock both through unity and PRL but the customer service agents were great about relaying information to me and got me the parts quickly. I love the extra little boost and the added engine noise. There wasn't any instructions for it but there are a few videos that explain it. I was able to install it without taking off the front end.

Haven’t had the mount for too long, so can’t really discuss durability, but impressed thus far with the quality and price. It is obviously 3-D printed so if you’re looking for something without any visual imperfections, this is not it. However, it functions very well and fit as expected, that I would mention if you don’t put something in between it, it can scratch or rather will scratch the plastic where it mounts. I just wanted something that would fit well and avoid drilling holes in my bumper and was a reasonable price. They did all that and it looks good too. I would definitely recommend this to others and I would buy one again.

I used to have a 70A aftermarket RMM for 3 years to improve the wheel hop issue and shifting experience. While the mount performed good for years, it was a bit too much when it comes to NVH when it comes to starting the car and cruising at low rpm. And I wanted something that balances both performance and comfort as I daily drive my Type R, not saying the previous mount was unbearable but I’m very sensitive to NVH.


Until I came across many research on forums and personally consulting Humza, I chose to go with this Wunderladen 75A mount, dnd I finally got a free weekend to have it installed (with the Whilteline RSB I got from Humza years ago). The moment I started the car, the difference is mind-blowing: the buzzes I noticed with the previous mount was gone immediately without the Wunderladen RMM running in for a distanced drive. The feedback of shifting is so good whenever I was driving normally or spiritually without sacrificing too much of comfort instead of NVH, wheel hop is almost gone like what it designed for. And it all happens within the drive less than 150KM after I installed the mount.

Besides, visually it looks beautiful and tasteful, yet a functional and affordable piece without breaking the bank, suitable for anyone who wants more performance out from the car without sacrificing too much daily drivability, while the NVH is negligible and the trade-off is really worths imho.
If you are not sure which RMM to go with, this is the one!

Kudos to Humza - his feedback and services are as usual no match and top-notch since Day 1. Keep up the great work!
