Will this cause any problems for my bike?

The exaust i fitted recently is just too loud for my liking.

The baffle fitted Had a hole straight thru the middle.

I noticed some baffles have a plate before the straight thru section so i thought i'd try to make one.

This is just a temporary one to see if it made it quiter, which it did.

I'm going to make another one with some good ali.

So will this cause problems for my bike?

It is no bigger than the plate behind the jubilee clip.

Hmm

It does't appear to effect the air flow it just has to travel aroud the plate, thus quietening it, instead of straight out.

OK.

I've cut it down so it's slightly bigger than the hole and moved it about 20cm further away.

Anyone else any input.:silent:

Won't they catch fire when the exhaust gets hot?:rolleyes:

Weld some gauze across it or do as you have done (but I wouldn't clamp it in place like that).
Think I actually have a spare one of those pieces you've tried to recreate, sod's law will strike me down but I guess I could post it down if you're happy just securing it with a couple of tack welds.

Just come back from a blast and the difference in noise is like night to day.:D

It has a much more rumbly sound as opposed to the LOUD ear splitting bark it had before.:D

Runs fine all the way to the limiter.:D

And is much more acceptable around town.:D

Now to make a stronger one out of ali.

Hey Dave why would it not be good to secure it with a jubilee clip?:confused:

Oh and Dave i appreciate your input.:cool:

I would worry about the clip snapping/rattling off. Had a few snap/slip on the outside of the SV's pipework wouldn't be particularly happy that happening internally - but the forces will be different there, so it may well be fine.

OK.

I've left the cat in so that may stop anything making it's way back into the cylinders.:p

I'll have a think about attaching it more securely.

Thanks Dave.:D

Second thoughts probably best to make one from steel and tack weld it.

Dont make it out of ali, it will fatigue and break in a few 100 miles then your exhaust will rattle. Make it out of 1.6mm steel plate and weld to the baffle.

i come from a 3rd world country and what we do is pack the baffle with steel wool and it works a treat.... just pack it hard or it will just blow out, try it , if your not happy with that just take it out, worth a try dont u think.... lol...:D

Err...I can't even hear my exhaust when I'm riding, because it's behind me, and mine is fooking loud without the baffle in.

^ i can hear mine over my ipod ;) so your's cant be that loud

Then you're either going too slow or need to turn your ipod on. Exhaust noise is blown backwards...simple logic.

Thanks.:cool:

If you're dead set on being pig-f***ing spacktarded and making your bike sound like a sewing machine then feel free to send me your baffle and I'll TIG you a bit on for nowt.

However... a properly packed can does not sound so harsh, I'd bet your can has just eaten it's packing and needs redoing to bring the noise back to a nice but inoffensive level. What can is it and how many miles has it done??

The noise is a lot quieter with the temporary plate installed.

Thanks for the kind offer to weld it.

I will try and have it done locally.

Do you think it will be OK and won't effect the running of the bike?

I need a lie down.:smt046

Thanks for your very valued input YC.:smt046

It will be fine just don't expect best power out of it. Stubbies don't seem to work on the SV.
