Quieting your loud cold starts

[Rapid Red]

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.

You're correct it does have a quiet start mode, remember seeing it one time. Before I cut the AE off and installed the Roush, great axel backs.

I didn't opt for this, but I see a ton of people removing factory active exhaust, so I imagine those axle-backs are available all over the place. Not sure how the wiring would work on a car not equipped with it. Maybe some type of manual switch can be fashioned?

Roush is out of their minds. $1800 just to convert their overpriced exhaust to an active? $2800 for the full cat-back kit? I guess a sucker is born every day, but are people really paying this?

When you order a Roush package, the active exhaust is an option. Personally, I think the Ford version is better...and I made sure it was on the car before I bought it. I was surprised at the cost of cat-back systems. I looked at the Corsa Extreme and with active exhaust, it's like 2600.

After doing the Steeda H-Pipe, I'm happy with how it sounds. Next will be the FP intake/tune...or a supercharger.

Yeah I did the Steeda H-pipe this week and I'm of course still getting used to everything about the car, but it sounds great to me. In no way does it sound like a typical factory style exhaust. It has serious growl to it. I like how it still goes to fully tame on the highway in overdrive. The stock parts look really well done. I am not in any hurry to change the rear section, if ever. I like the sound of Flowmasters, but it feels wrong to remove stainless mufflers for carbon steel Flowmasters, heh.

Like you, I am/was shocked by the prices on cat-backs for these cars. This is the kind of crap they used to do to Corvette owners. I guess the buyers of these cars have gotten older with more disposable income (which I assume is why Corvette exhausts were always expensive). I remember paying $600 for Borla fully adjustable (swap plates) FULL cat-back system with beautiful quad tips (for a 4th gen f-body).

Dude...I had a 97 Pontiac Formula 5.7 and did a full flowmaster catback, quad tips, Moroso CAI, MAF spacer and 160 thermo for under 1k. Ended up putting headers on that car...which I'll NEVER do again. Not sure if it's inflation or what, but $400 for a CAI is nuts imo.

I feel like it's even higher than inflation by a good margin. Yeah, not paying $400+ for a CAI when it literally produces no gain over stock. I also owned a '95 Camaro Z28 LT1 and I put on MAC headers, which didn't cause me any issues. They were pretty good for the money, and it wasn't a lot of money. I also had a '00 Z28 LS1 (that's the one I had the Borla exhaust on). I think it has to do with whatever people will pay ya know? Even that same Borla, which is still sold in websites, is under 1k to buy. It seems to be $1500+ for an S550 cat-back.

If you are thinking in a catback, Terry @beefcake gave me a really good deal and mine was shipped to Puerto Rico. I have the AWE-Tuning Touring and sounds amazing.

I used to think so, too, but I've been proven wrong.

Thanks for setting me straight. And for posting that other thread. I’m going to do my own video test now. There still seems to be some confusion on the impact of the scheduling function and quiet mode setting. (I’m still going to try the noodles but maybe only in the non-valved output first. )

If the Harley d-bags with open pipes can sit and rev in the driveway for no good reason, then I think someone can start up their Mustang to go to work. j/s

post the video! id like to see how the noodles work for others . also interested in this active exhaust topic too. i dont have it, so obviously havent played around with it and how it functions, but interested to see how it actually works. would seem to me to defeat the purpose of having quiet mode if it starts up valves open and then closes them.

dont forget to check used stuff. i bought a used roush axle back from a local guy who accidentally purchased them for an active exhaust car (he had the non-AE roush for his AE 2021 GT) they were in like new condition and i saved like $200 over brand new ones. with something like exhaust, i dont care about normal rock scratches and chips that will inevitably happen as soon as they are on my car anyways.

i hear you though about the prices for aftermarket parts for these cars. whenever i check prices for the fox/SN 5.0 cars i am shocked at the difference. full catback for an SN car can be had for sometimes less than just a non/AE axle back. and headers-shit, pushing 2k for certain longtubes. i think i saw Kooks LT's with green cats for around 2k-ish just a few days ago in a catalogue. i helped my buddy put texas speed longtubes on his 2021 that he bought 2nd hand. were they dirty- yes. did we care? no. they had no dents whatsoever, flanges were great, fit was great, no leaks. who cares about them not looking new, they wont after being driven on his car anyways. think he paid $500 or so for them, and we put them on, so no cost there either. PITA to install but that's part of the game.

Ha, and we think you have it good. Do a search on some of your favorite/common parts on a .au search engine and have the tissues ready for the nose bleeds.

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

I can only imagine, and i do not envy you!

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
