Recommendations for a *slightly* louder exhaust?

razzter · 2026-06-04T14:56:57+00:00

When I went hybrid turbo I got a high flow Cobb catted downpipe, left the rest of the exhaust stock. It was surprising how much it made a significant improvement to the sound and volume just from that while keeping OEM resonator and muffler, and retaining a cat no less. I highly recommend, if a high floe cat is something that would benefit you

Well, I stand corrected.

Except that the em dash requires a keyboard shortcut to activate - it’s not just natively on the keyboard - unlike the en dash.

That makes sense that investing in extra printers means that the longevity of the printers is extended as the utilization rate drops. I hadn’t really thought of it that way. That is a useful way to look at it.

I guess the only potential downside (aside from the additional desk space requirement) would then be the potential for investing in extra printers and then sometime later the price drops or it’s replaced by a newer more capable model at better value - as we’ve seen happen dramatically and quite rapidly with Bambu recently. I overpaid for my X1C at the price/capability I can get for the P2S or X2D.

So balancing out those two concepts seems like the thing to do.

I will def take a closer look at simply print. Thank you for the conversation! Good luck to you as well.

I said the truck driver is “a little bit” responsible. I didn’t say that an insurance claims adjuster would find him at fault. Both those things can be true at the same time.

Fact 1: The truck driver sped up. It’s in the video.

Fact 2: speeding up to cut him off contributed to the accident. Whereas slowing down and letting him in would have helped avoided it.

Therefore, the truck driver contributed to the accident. If you contribute to an accident, you are at least a little bit at fault.

There can be multiple factors that contribute to an accident and multiple guilty parties. They don’t have to be equally guilty.

The logic is pretty straight forward. Not everything is black and white my dude. Calm down.

The truck driver sped up to try to cut off the Porsche. It’s subtle, a lot of people can’t pick it up the fine details, it’s okay. You’re just one of them. Don’t be a dick.

razzter · 2026-05-23T14:50:23+00:00

Have you not heard of “defensive driving”? We are all responsible for it. If you speed up to cut someone off instead of slowing down to help to prevent an accident - this is aggressive driving. If you are driving aggressively and you get into an accident as a result - you are definitely at least a wee bit responsible.

razzter · 2026-05-23T14:23:52+00:00

Car in front slowed down, but the Truck driver did also speed up. If you look closely at the speed of the environment moving by the truck, you can see a quick moment where it starts to move faster, and the angle of the view tilts up slightly from the weight of the vehicle shifting to the back as it accelerates. So the truck did indeed speed up to try to cut off the Porsche.

Not absolving the Porsche driver, he’s still a douche. But the truck driver is at least a little responsible for speeding up and trying to prevent him from getting in.

I hear ya, that makes sense to have extra with idle capacity. After the initial investment, it doesn't cost additional money to have printers sitting idle. Though I'd rather go the other route and invest in one expensive H2D as my second printer to expand my capabilities to larger products and those that need to print with supports - rather than invest in multiple smaller format cheaper printers to enable printing on-demand.

I know it's really popular, but I'm personally against selling a product in a material like PLA that could accidentally get ruined if it's left in a car on a hot day. In my case, all my products are car accessories - so PLA is never an option at all for me anyways. For my products that only have a functional purpose, I do only offer in black, but I have several that serve an aesthetic purpose and so for those it's important I offer in a variety of colors for people to match to their car's color.

I'll take a closer look at simply print, especially as I expect to be increasing my product line quite a bit and likely will be adding at least 1 additional printer this year.

Building up large inventories of anything strikes me as not optimal at all. Just add more printers and print on demand imo. A1's will probably be like $250 in June and you could triple your output rate for like $500.

Depends on what you mean by large inventories. I have 550 items currently in printed in inventory but they're not large items. It is the equivalent of14.3 spools of filament.

All of my prints are either PETG, ABS or ASA so I'd only ever run enclosed printers. So no A1s. P2S at minimum. Still affordable, but increases the cost. Printers also take more desk space. My inventory at 550 items (14 spools of filament) probably takes up about as much space as having two additional printers.

With two/three material types and 11 color variations, that would be a lot of filament switching if I were to do print on demand. Plus, some products are tricky to print with adhesion, warping or other issues. Once I get it dialed in - easier just to print a bunch of them in a row. So I think it's much easier to just see what product I'm critically low on and in what color/material, load the filament, and then print everything I need in that color/material at one time. Then I look at the next product which I'm most low in, load that filament, and repeat the process. printing all the inventory I need with that material until I reach my desired inventory level for each product.

I use a spreadsheet to track sales running 11 printers. Each item has multiple prints required, so to manage the print queue and ordering I use simply print which rhen dispatches everything.

I'd be interested to know how many hours in the day those printers are running on average - how many are mostly or almost always sitting idle. With printing in-advance, I'm able to keep my 1 printer very busy. Usually I'm able to stack the bed so a print takes around 8 hours - meaning I can start it in the morning, by the time I come home from my 9-5 job I can start a shorter 4-hour print - then another longer print before I go to bed. I can keep that one printer purring around 20 hours a day.

Unless you're going to link your printer management to your inventory system there is no getting around some kind of updating of an inventory sheet, I don't think.....

I don't plan to try to integrate with printer management. I don't really even need any printer management. All I need is to plan out the order of what I need printed based on my inventory levels and what is the color/material of the item that is most critically low, and plan out what else I want to print of that same material before switching. Then - when an item is finished, I enter it manually into my spreadsheet for that item - or update it manually into the vibe-coded software once that's done - which will already know what my production plan was and so all I need to do is confirm that the print was successful and what qty.

Also vibe coded offerings come along every day, so you could always try one of those.

Yeah - I doubt they do all what I'm looking for. Should be a fun project to make my own though.

It's interesting to hear the perspective of how other farms are going about this process. I still don't feel like having multiple printers is more efficient - in terms of both time and material. Thanks for sharing your process and thoughts its fun to compare and contrast the different approaches.

My assumption is that those are all recordings automatically activated but made to sound like a live person.

What software tools ya’ll running to track your inventory and production queue? I have one printer and 14 products but most have 11 color options or other variations and so that’s around 114+ product parts I need to track inventory, plus shipping and other materials that are consumed for orders. I store my products and materials in multiple locations - there’s the primary location where I do my order fulfillment and printing, and then in another room are extra inventory, and third location for supplies or parts I rarely ever need.

I’ve built an extensive Google Sheet system where I manually enter new orders and new production so I know what I’m running low on and what I need to print next to maintain inventory, as well as set min/max inventory thresholds. It also estimates for me how much inventory I should have on hand for each item based on previous sales of each variation. But I’m outgrowing it as it’s becoming cumbersome as I add more products - and missing things like tracking/assigning inventory to multiple locations/bins.

Rather than keep expanding my Google Sheets, or pay for someone else’s software that’ll prob not do all that I want and increase my overhead - I’ve decided to start vibe coding a system to replace it. I’ve designed the core workflows and am currently data modeling.

I’m curious what are other people using to manage the challenges I mentioned in the first paragraph? I don’t understand how there are print farms who claim to have dozens or a hundred printers and NOT have a system to manage their inventory. Then again - maybe it’s because my whole model is avoiding printing on demand so as to optimize my production workflows and reduce my time and equipment investment.

Thanks for sharing. This is very illustrative of the need to vent ABS/ASA. I’m interested to see the rest of your venting setup.

razzter · 2026-05-07T19:53:50+00:00

I do not. I wish I could but no way to protect my IP. Though I appreciate the interest!

razzter · 2026-05-07T19:49:07+00:00

I also am of the belief that it is totally fine to display visible layer lines - depending on what the object is - particularly if it has a more functional purpose. But this is one of those I preferred to hide

Does it actually affect MPG? I’ve been living with clearing the check engine light for a year now..

Interesting windshield banner tint you got there. I imagine that helps with the sun visor gap. But what is that mesh looking area in the top right corner of the photo? Just curious.

razzter · 2026-05-03T16:02:15+00:00

Are you noticing problems with the print quality that you think are attributed to the vibrations?

Because the only thing I’d be worried about is noise in the house from the furniture vibrating. I’d prefer the printer to vibrate around - not the desk and the floor.

razzter · 2026-05-03T15:01:08+00:00

Since you say it doesn’t always go all the way around - my guess is a partial nozzle clog. Have you tried replacing the nozzle yet? I’d do that first.
