LOUD NOISES! Installing ARM Catted Downpipes On My F80 M3 (Plus Sound)

Рет қаралды 1,968

Күн бұрын

Time to replace the last piece of stock exhaust restriction on my F80 M3: downpipes. Specifically a set of ARM catted downpipes.
This one was a process (both to film and install). I tried to note a few points of interest beyond the typical installation routine so hopefully it helps anyone else doing this.
Tools used (most of these are linked below):
6, 8, 10, 11, 13, 16mm sockets/ratchets (an army of sized variants and extenders is helpful)
22mm (7/8") wrench or O2 socket
E10 torx
T15, T30
6mm allen (center exhaust brace)
Pry/trim tool
Torque wrench
Flathead screwdriver
Thanks for watching!

Very in-depth video. I’m tempted and considering ARM dps (resonated though) with mini cats. Gotta love loud noises!

Appreciate it bro 🍻 Gotta tell ya, the car is a different animal afterwards. Bit of a hassle, but worth it. Though I just put in the replacement downpipe and it's crazy how much easier it was the second time lol.

I am trying to figure out the exhaust setup for the summer. May go equal length for AA but have heard single and it was fantastic.

@jgo.m3 5 ай бұрын

Yeah man, I'm already getting the itch to try something else out and I know I shouldn't (still very happy with the Valvetronic exhaust) but tbh I'd love to hear a single mid pipe on mine. I had the AA ELs and they were great but from everything I've heard, single gives an even deeper tone.

Thanks for the video! I started watching because I after I installed, which like you said was a pain, I had the same issue with the transmount bolt. I wanted to see if I had done something wrong but I got the same “bad batch” from ARM. To their credit they sent out another long pipe asap but same issue. Went with another popular 200 cel dp fitment was great but sound is not the same. ARM definitely has the best sound hands down congrats!!

@jgo.m3 4 ай бұрын

Thanks brother! Sorry to hear you had a hard time with yours. Did you notice any rasp afterwards? I feel like there's a little bit there on the low end if I'm in a higher gear trying to get up to speed, but it's not terrible (certainly worth it lol).

@ianounanian8990 4 ай бұрын

@@jgo.m3 there was a small amount of rasp when down shifting and as you mentioned when getting up to speed. Slowly accelerating yes rasp mainly gears 2-5 but if I floor it no issues.

@jgo.m3 4 ай бұрын

Exactly the same here. I guess a little rasp is unavoidable when you mess with down pipes.. especially with equal length mid pipes.

@ianounanian8990 3 ай бұрын

@@jgo.m3 I have same exhaust, I am 90% sure that even the owner or the guy that has done all their videos, had mentioned that the rasp never completely goes away but that it was/is great reduced. Like you I researched a few brands catted brands and honestly the deciding factor to go with ARM originally was emailing VD and finding out that was the downpipe they were/are using for their videos. Another thing that I wish someone had the time to do, would be to get sound clips of the different 200 cel cats. I am curios to see what factors truly change the sound, performance, etc especially when the price points vary so much. The ER are beautiful and fitment could be amazing but what if the sound was awful? The brand I am with now, has 3 letters, and almost identical price point you can figure this out of course. I will say the sound is deeper, which is ok still think ARM has the best sound, it also seems with this brand, the downpipes are more restrictive at lower rpms and not as free flowing. On a side note i did reach out to VD and asked them if they would be expanding their offerings to include downpipes and they said "not at this time". Anyway I apologize for the lengthy response and will be interrogating you on your BM3 post. Thanks again as always for take the time to post these videos.

@jgo.m3 3 ай бұрын

Anytime brother.. appreciate you taking the time to comment/chat. Yeah pretty sure I know who you are talking about.. I considered them too but ARM had so much more feedback/examples and I do love the sound. I agree though it would be cool to hear a lineup of different setups. As for ARM I hope they iron out the QC issues cause they do make good products and have insanely great customer support.

Just did this on my f80. It sounds amazing with valves open. I’m thinking about removing the secondary cats to get a little more volume but not get too crazy

Nice 👍 yeah I think the volume without secondary cats is fantastic.

Did you do them on yours? I’ve been trying to find a video of catted dp’s with a secondary cat delete (and stock comp exhaust). Hard setup to find a video of lol

@jgo.m3 4 ай бұрын

@@_allenyang I have the Valvetronic Designs exhaust which gets rid of the secondary cats. If you wanted to keep the comp muffler you could just get catless mid pipes but you'd have to cut (which has the downside of not being reversible). I'm pretty sure I've seen a video of that before.

@@jgo.m3 makes sense. Leaning towards it! Appreciate the insight. Btw I’m in Delaware too, pretty sure I saw your f80 the other week. I just picked up my mineral white f80 last month from ottos

@@_allenyang nice! Yeah I think I saw you - I remember seeing a white F80 thinking "well that's new around here" lol. Very cool. There's actually another yas marina F80 in the same area (Hockessin) but his grill is chrome whereas mine is black. Anyway if you ever wanna catch up and compare notes on mods or whatever, let me know. Also watch out with (formerly) Otto's when it comes to service. I posted a video on it recently if you want the full story.

Currently rocking a Remus race catback but would 100% choose the resonated catless DPs for my build! Just debating if I should go with a Resonated EL?

@jgo.m3 5 ай бұрын

Personal preference of course but if it were me I’d go non res mid pipes if dps are resonated.

Is this valvetronic with catless down pipes or resonated ? if so im getting rasp/drone from 1800-2k that im not hearing in your video.

@jgo.m3 Ай бұрын

Nope, I have catted down pipes. Catless dps with equal length mid pipes (like on the valvetronic system) will cause rasp. I actually do still get a little bit, but only if I floor it at low RPMs in a higher gear. Also, beautiful F80 you got there! Subbed 🍻

Haha nice! I knew I should have hit them up for a referral code. Sorry to hear about the rasp but otherwise hope you're liking the setup. I know mine is pretty insane with catted dps so yours has gotta be a beast at full throttle 🤘
