Hi all,
Lately I find out, i'm not noticeable on the traffic....so I wish to get a Goldstar silencer. Is the Goldstar silencer fit with Royal enfield 500cc Injection model and Is there any modification needed, or re-tuning etc after install it later? How bout the sound and peformance, is it will produce good loud sound of "thumper" and increasing power?

However, there are two company that produce this Goldstar, one from (sansclassicparts.in) and another from (classicbikeshop.co.uk). Give me favor, which one is a more loud and have a good quality?

Hope you guys can help me to make a good decision

Haha, if you want Loud you should take my aftermarket fishtail LoL!  THAT is loud!

Loud pipes will not make you more noticeable to most people who are in a position to kill you, sorry to say.

The SANS items are hand made in Inda to a fairly crude standard.  They're worth the cost in India, where nothing else like it is available locally and you pay little in shipping.  (I'm running one of their mufflers here in India myself...not a gold star, though.)  Don't know shipping cost to your location but I imagine it's more than the cost of the muffler.  Also don't know anything about how they work with an EFI bike.  If you're on a carb'd bike and replace a restrictive muffler with something freer-flowing, you will need to richen the jetting, for what it's worth.



If you can pay a lot more and don't want to ask any questions, Hitchcocks sells a Goldstar made for the 500 EFI bikes.  It's made in England and likely of much higher build quality.

Noise won't help as much as increased visibility will.   Wear brightly colored protective outerwear that has reflective stripes for night-time.

[no bs]

my co-workers can hear me coming down the freeway with the sportster "silencer". every little bit helps!

I'm guessing they are standing out-side for the "morning meeting" when they hear you coming.

other drivers, cocooned in their air-conditioned comfort barges will notice the safety-green color before they locate you by sound.  (unless you point the exhaust forward).

[barenekd]

Have you ever been driving a car and have one of those 200Db Hardlys pass you? Have you ever noticed that you don't hear them until they are right next to you?
Don't you realize that loud pipes don't save lives, they just piss people off!
Not that I have anything against a reasonable amount of noise, I generally make it myself. But you don't have to be heard two miles away to enjoy it.
As for the Gold Star pipe, the Hitchcock pipe is very nice. It comes with a removable insert in it that is reasonably noisy. It sounds pretty good and shouldn't send your neighbors running. With it out, it still isn't terribly loud, but it could grate on some people. As for shipping I think Jack paid $75.00 to get his here from Hitchcock. It as fairly quick shipping though, Less than a week.
If you ant a bit more noise get the $69.00 Dominator from Motorcycle Superstore. It's listed in their Sales or Clearance section. That one is pretty loud, but can be packed with fiberglass muffler stuffing.
I had an EFI muffler on l mine and it as about a medium noisy thing. I could hear it a block away, but it wasn't irritating, just a nice thump.
Do not get the whole GoldStar exhaust system from Hitchcocks. The headpipe is too big for the UCEs EFI tuning and they will lose a lot of bottom end power.

If you want a loud exhaust , you might do what I did  I installed a EMG 20 inch turn out muffler , but the problem with the turn out style muffler is it doesn't mellow out when cruising at speed it gets louder , after about 120 miles it was about all I could take , I removed it and  installed a 17 inch megaphone muffler with a 12 inch exhaust extension to move the rear outlet to the back of bike. The fellows I ride with say it is still loud but I don't notice it as much. As far as being seen ++1 on wearing bright clothes ,because an older person who doesn't hear well , a loud bike is not going to make a difference , you have to be seen.

Huh? Older people can't... what did he say? SPEAK UP, SON!!

[bikesnob]

I installed a Gold Star EFI muffler on my Bullet, went on real easy no modifications needed, it sounded great too, never took the baffle out.
I no longer own that Bullet, moved on to a Bonneville, I sure hope Bare will forgive me someday!

Which Bonnie did you get? 

Norman Hyde Togas sound good, really mellow, just like an old British bike should sound.

Sorry for the thread jack.

I'll steal that response from bikesnob. He got a T100 with an Arrow exhaust. BOOO!

i have a black D&D full exhaust (about 2000 miles on it) with the uni air filter and k&n crancase breather for $250+shipping.

the D&D is loud.

yeah, they're outside.our workplace fronts i-80. the guy that works next to me said he could hear me coming before i passed him one morning. i didn't realize it was that loud to others.

Love the sound of the Arrow Exhaust, especially with the baffels out not really to loud.

I was looking at getting the D&D when my funds allowed; do you still have it ? most importantly why are you getting rid of it?

[Gypsyjon]

I put a Goldstar on my G5...do not know if it has baffles or not...I just know I could look in one end and see out the other....has a great bark, which I love. Simple install.

[Karlos-1971]

I put a Goldstar on my EFI B5 a couple of weeks ago together with a K&N pancake filter fitted inside the existing airbox. It is attached to the standard header pipe and is not upswept. The mid range torque is certainly up compared to the standard torpedo exhaust system, it seems to rev easier too and the bark is great. However, it has also added backfire to the noise "profile" which is less attractive here in Australia! The Goldie is a straight through as described by a previous poster - anyone else had problems with a backfire after the exhaust change ?

[TWinOKC]

Welcome to the forum Karlos.  Backfiring is sometimes caused by an exhaust leak or running too lean.  Check all the exhaust connections first.

[Arizoni]

Personally, I wouldn't want a straight thru silencer on my fuel injected RE.

When straight thru silencers are installed on a carburetored bike it always makes the fuel/air mixture run lean which causes the engine to backfire on deceleration.  To correct this, larger jets are installed in the carburetor.

With a fuel injected motorcycle I believe there is a limit to how much the ECU can do to enrichen the fuel/air mixture if a straight thru silencer is installed.

When I installed the Harley silencer on my G5, I drilled a few holes thru the deflector plug to increase the exhaust flow and then rode the bike listening for the tell-tale backfire.
I continued this drilling and testing until the engine would just occasionally 'pop' on decel and stopped right there. 
The spark plug shows normal colors after some 6000 miles of riding so I think I've got mine set just about at the limit.

I suppose a person could adjust the TPS (Throttle position sensor) to obtain a richer fuel mix but there is a chance of frinkling up the setting for other throttle positions. 

[High On Octane]

The TPS has no adjustment, and even if it did have an adjustment, it would only adjust the idle speed.  Richening an EFI fuel system can usually only be done by either replacing the O2 sensor with a wide band sensor or by reflashing the ECU to spit out more fuel through the injectors.

[JVS]

The TPS has no adjustment

There is a way.. (without any reflashing, tweaks to O2 sensor etc)
ScooterBob and Ducati Scotty and a fair few know what I'm talking about lol. They were a great help.

I richened the mixture by adjusting the TPS idle voltage when I installed my EFI silencer as it used to backfire a bit back then. But I returned the mixture back to its default idle voltage after a few 100 mi. My spark plug has been at the optimum colour it should be. NGKBPR6ES with a 0.7mm gap and idle set around 950RPM. Backfires very rarely.

Interesting........  Just one more thing that makes fuel injection a PITA IMHO.  I'll take a carb over fuel injection any day of the week.

This is my first bike..and I wanted a cast iron Bullet. However, it was hard to source an iron barrel here in Australia, plus the used ones on sale go around $5200+!!  So, I saw the B5..it matched the Bullet I wanted, but with the newer engine. I decided to purchase the UCE. Hitchcocks have the carb conversion set-up for the EFI. I might go that way in the future..or just buy a CI also. I want to experiment with the carbs as I've never done it before in my life lol. I might just add a petcock to the EFI rubber pipe just to mimic some of the carb's coolness 

[High On Octane]

Don't get me wrong, fuel injection is great when it's working properly, but there is WAY TOO BIG of a grey area when sensors and relays start to go bad.  Sure you have an MIL light, and it will tell you the problem, but they WON'T always tell what is CAUSING the problem.

It's still weird to me that a TPS sensor would have an adjustment on it.  You'd think it'd be preset and there wouldn't be any need to monkey with it.

   This is a good read, if your interested.  It's from the Car world, who are probably LIGHT years ahead of the bike world . But a lot of it apply's here.  There is also MUCH to be learned from the younger guys, who tune on ..... well ? .... Those tuned Cars that they drive. They get into tuning individual Sensors!....... Pretty crazy stuff. But it's pretty interesting if your into it.

Holy crap that's a lot of reading!  No thanks.  Give me my old school carburated iron headed muscle!   

To keep on topic, I run cocktail shakers on my '58 Trailblazer and they are plenty loud.  Not sure if they would work with the UCE motors though.

The Throttle Position Sensor (physical)adjustment is NOT the correct way to fix A/F ratio troubles.   Those type of "fixes" are promoted by people without modern skills who try to "trick" the control system into performing differently than programmed.

The correct way to address these issues is to adjust the table offsets in software, that way you maintain the entire operational envelope of the engine (and not just scrunch it up on one end).

[Arizoni]

Right you are, but of course the ECU on the Royal Enfield cannot be adjusted without the necessary unavailable software from the manufacturer.

The voltage put out by the TPS varies with the position of the throttle and this variation is used by the computer to know where the throttle is positioned.  From this, it can calculate the correct amount of fuel needed to assure the correct air/fuel ratio.

The reason I mentioned the TPS as a way of changing the air/fuel ratio is because it will do that but people reading my earlier comment should notice I also mentioned that doing this can screw up the mixture under other conditions.

Th software is available from the manufacturer. The problem is the $2500 or so cost to the shops!
