Quieting your loud cold starts

[FreePenguin]

Hah, I understand, man. I am just ragging on the HD guys. But as a lifetime "car guy," I think Harleys (and V-twins in general) sound like complete a**. They always sound like something is wrong with them, and their power output is unimpressive for the size... but I know it's more of a "culture" than anything else, and people would argue that a twin-turbo 6 could out-perform our Mustang V8s, too *shrug* But yeah, I have neighbors who are always out revving that thing and it always sounds broken

No doubt, I enjoy my sportster. I get 50-60mpg cruising w my gf. May sound broken but works great for scooting around. The pipes I have aren’t allowed anymore, due to noise and emissions. Screaming eagle 2’s

they was sold at dealerships even tho didn’t meet emissions what I read, got fined hard and removed them.

Potato potato potato lol

lol my Harley sits in driveway for like 10 minutes idling before I take off. carb' if I dont it stutters, I mean I could use the choke, but I rather just start it, turn choke off and let it idle til im ready and roll out so its mostly warmed up.

potato potato potato potato potato- but the Harley gets like 500 miles a year and its only during summer mid days, never early or late

My neighbors are like...what's he doing next...

I've always felt the same way about the sound of Harleys.

I was going to argue that the best sounding engine I ever heard was a v-twin. Ducati 996 with termi’ exhaust with the mechanical Desmodromic valvetrain and dry clutch was such a mechanical symphony.

But all the videos I could find sound like they are self-destructing….

Hard to beat the italians when it comes to engine noise. The F133 V12 is another glorious engine to hear in person. And the Busso V6. And dozens of others. Lol

Just a comment from Australia "down-under". I have a 2019 Bullitt with AE and a Steeda H Pipe Res Delete. On a cold start, it barks and cracks, so much so that when first heard by the neighbours, they thought that their House Air Conditioner had exploded and went to check. I will try the noodles for early cold starts. Thanks for the tip.

What if I want my cold start to be louder? Hehe. I love the ridiculous bark the car has on a cold start. This is with only a Steeda H-pipe on an otherwise completely stock car with 200 miles on it.

I took this video a few days ago.

For me, the motorcycle sound I love is a DOHC inline 4. My dream bike (before I was prohibited from buying one) was a Kawasaki ZX14r. It's just a difference in ear, I guess, just never liked how V-twins sounded. I think they exist mostly for nostalgia rather than function.

interesting, i did not know that. i recall reading something about being able to set active exhaust to start in quiet mode at certain times or day, or something like that, to allow you to start the vehicle quietly if it's early, late, or whenever you dont want it loud. i never read into it as much as you explained, however. i can understand the purpose of warming the cats up quickly via adding timing and fuel, but i am unsure how leaving the active exhaust valves open during this process helps.

Thanks for the clarification though and explaining that

but yea, bottom line, if the car is still louder than desired even with active exhaust/quiet mode, the noodles will still work. i paid a whopping 8 bucks for 2 of them haha.

I can on my 350...but you do it by holding the clutch in a couple seconds before start up and it closes all the baffles

your car sounds great! i like it.

dont get me wrong, i love the loud bark on the cold starts, i scared the hell out of a work buddy who was walking behind my car and i used the remote to start it after it had been sitting 9 hours. but there's a time and a place, and 4 am every day aint it, ha!!

i helped a buddy put long tubes on his 21gt, already had an X pipe and factory active exhaust. christ that thing sounded wicked when we first fired it up.

good luck, hope you have some luck with it.

Great write up! I'm sure many neighbors (and wives) will be pleased with the sound reduction from those of us who make a point to do this during early morning cold starts.

A little late to this thread... My PP1 is not a daily driver... I have Kooks 1 7/8 headers, 3" from the collector all the way through to a Borla ATAK cat back. And mine is A/E... I start mine in quiet mode before 9am with the garage door closed for the first 45 seconds. I leave the neighborhood in quiet mode (again before 9am). That's about the only curtesy I give my neighbors. As far as my HD VTwin... I let it rip (zombie mufflers with V&H headers) regardless of the time. My neighbors don't say a word... but they need me more than I need them... I fix everyones cars, remove snow for most of them... basically the first person they call when they have car, bike or home issue.

that's good! mine have been pretty cool about it overall.

how is yours with headers and AE, quieter than the HD im sure, but what about the mustang if you cold start it in sport or track, rather than quiet mode? i assume catless LTs??
