Hi guys
The standard pipes on my VT750 are just way too quiet :sleep:
what would be the easiest and cheapest way to give it more sound without having to buy V&H pipes or ripping the baffles out somehow and losing all back pressure?
:eek:

Take your ear plugs out when you go for a ride.

Sharpen the end of a bit of Rebar and beat it down the end of your exhaust with a mallet.

upgrade the stator and add a few of these?

then put some devildriver on, and turn the volume up to 11 :eek:
Seriously though, need more info about what type of muffler it is. You could take the lid off your airbox too, might make it a bit louder and you shouldn't need to change the jetting.

In the outer ring looking up the pipes drill 4 holes with a 8 - 10mm drill top and bottom and left and right, will give you some more sound, you can also debaffle them but the above will possibly give you all you want.

Mufflers are just there to satisfy emissions standards. Take them off.

You can hack the existing muffler, but it will sound like shit.
"Loud" pipes have a resonant chamber to amplify the bass, and filtering to chop the high-pitched sounds, and your pipes have neither so hacking it will just make it sound all farty and loud like theres a hole in the exhaust.
If you reeeeeeely must have a "loud" pipe on it and you dont want to pay, then find a 2nd hand straight-through two-inch car exhaust and get that welded on and spray paint the lot black. It will look like shit and its a car exhaust on a bike (serious bad karma) but hey you get what you want.
You might find something a little better than that in trademe bike exhaust category.

As if you haven't done the same to one of your poor bikes.

I once welded 2 Coby Car Mufflers on to a 1969 CB350.
Sounded like shit but fuck me it was loud!

Im with phillk on his one, did it to my 650Bros & also to my vt250....what I like about the drill bit method is that if you want it louder after 10mm holes, then take it up to 12mm...or 6 holes:eek:
If you take a minimum of care & punch the holes first you'll get it looking all professional like:msn-wink:

+1 for the drill out what you already have.
As a precaution, make sure you drill where you can get suffiicient access to pop rivet the holes up again.

how many holes does it take before the jetting starts to go out though? Not sure what the vt750 is like, but if its similar to the likes of the s40, hole exiting the muffler is about 3 10mm holes worth, so adding that may be pretty significant.

Look I know it sucks living in a country where a 250cc bike is like a Hayabusa but posting a pic of your transgender genitalia wasn't neccessary.

eat more pies...
gain weight like the rest of us and then you will need to ride round in a lower gear and higher revs, and therefore be louder...

Ifg that's a photo of your penis I reckon you must have no exhaust at all.

Shit we must be the same age. Was the rage back then, guilty as well but a 650 so it probably sounded a bit throatier.

not with one hole, but a couple maybe, heaps and it's a definite. Assuming a resonant chamber type muffler rather than a glass packed one of course.

I don't recommend drilling half a dozen 10 mm holes around the existing outlet hole. Past experience doing this years ago on a Kawa 750 resulted in it indeed being louder but it sounded like a pack of homos lined up behind the bike farting. Homos I believe fart deeper than the rest of us due to their outlets being unnaturally enlarged.
But back to your pipes.
Check the net for info re hacking your existing ones.
Or
Your local bike shop can order you a pair of 'Dunstal' mufflers - 2 styles available (see picture). They should be no more than $120 each and come with collars to allow the mufflers to be fitted over 3 different sized headers. Yes they are a Asian knock off but they are surprisingly good for the price - steel is a decent weight and chrome is very good.
I've used both styles - the top style with a more open end has a straight through perforated core that may be removed for packing or 'tuning'. Note these are fairly rowdy as the packing supplied is actually a collection of many old Asian men's belly button lint. Consequently it lasts about one week! Repack with some decent stuff ($20 a pack).
The lower style in the picture is a very nice looking reverse cone and would be louder than your stockers but I'd consider it a good 'touring' pipe - your neighbours will not mind this pipe. These have a chamber core that cannot be modified.
Both may require a custom mounting bracket or something depending on your ride but are good pipes for the price.

Send them down to me, with a Pak N Save pre-pay card to the value of a beer slab and I'll mod them for you. I've done it on about 7 bikes now, as well as made three sets of drag pipes with proper packing and baffles while maintaining "the sound".
