Standard baffles-just drilled or out altogether?

[bikerpiker]

Mark...it was hardly worth while gettin the Black n Decker oot for that ....get the 12mm drill bit oot, 8 holes that size is the law

Then when those sound too quiet , rip the baffle oot completely Agree with you though ,any amount of holes is better than none ,the standard system is waaaay to quiet

lol

[IgorVigor]

That exactly why I want to drill them

Big holes sound better
Where is that SDS core drill?

Thanks for the input

From Friday I'll have a 2 into 1 exhaust with a carbon akrapovic race can, so hopefully there'll be a LOT more noise. Also dyno day on tuesday next week!!

Nice one Jonesy look forward to the you tube vid!!! Btw, eventually got the grab rail fitted!

[geodude]

I picked up a set of standard cans on ebay for £56 inc delivery!! They should arrive tomorrow at which point i'll be getting the drill out again. Currently I only have drilled 2 x 13mm holes in.

[JIMMYJAMES]

Could i do this to my Microns? They are the fully road legal ones with fixed baffles and i cant see any way of getting it apart besides using a grinder on it. I can get the end cap off by removing the allen screws but the baffle is definatly welded in solid.

Ok, so I received the spare stock exhausts and am now starting to mess with the fitted ones. Originally I had 2 x 10mm holes in each (not 13mm as first thought)

I now have 3 x 13mm in each and it sounds ok. I feel the drill will definitely be out again soon

can you not just snap the weld on the baffle??

Been a while since I logged on :S

Still got the Firestorm (obviously )...

I have drilled 8 8mm holes in each of the exhausts

It sounds soooo much better now

Its got a nice gentle rumble now, but might enlarge the holes a bit more yet...

8 8mm holes isnt that loud, can still hear the engine whining (and the camchain rattling slightly, need to tighten the tensioners a tad )

I might just rip the baffle out completely...just a little worried that it will be too loud...

Anyone got a decent video or recording of it? Only ones on youtube are poor quality...

Mind you, my Vigor 650 had a sports pipe with a removable baffle, and with the baffle in, my dad could hear me accelerate up hills a mile away :S


Might make up a pair of plates just incase there are probs with the MOT (having extra holes drilled)


Probably a stupid question to ask, but has anyone who has done a full bafflectomy regretted it and gone back to drilled pipes?


P.S. Just so everyone knows, I do like a nice sounding bike thats got a nice bark to it and a bit of noise....I just dont like drawing "certain" attention to myself ...


EDIT: Just had a thought....
One reason I drilled the plate is to lean my bike out a bit as it ran a bit too rich...

If I do a full bafflectomy, will I need to re-jet? :S

Couldnt see an answer to the question so sorry if its already been answered...

[bikerpiker]

I knocked the baffle out completely ,(pics/thread on the forum)and certainly didn't seem too loud ,also i never needed to re-jet, my bike ran fine without a problem.

Fuel economy seemed better ,managing 46mpg on a few occasions ,i also made up blanking plates for MOT time ,but tbh ,i don't think it would've been a problem without them fitted .

[AMCQ46]

I have the baffles knocked out of mine as well, sound is great, but still quieter than the Microns I had before [which I thought were too loud, and brought the wrong type of attention].

On Jetting, I had already fitted a DynoJet kit for the Microns, and I run the same set up with standard cans and these debaffled ones, if anything I think it runs slightly cleaner with the std cans in that it is less prone to cough stalling, but I dont change the jetting.

MOT: , for 3 years I always re fitted the std cans "just in case" .......... but got lazy 2 years ago, and no problems, my MOT people are fine with the loud ones

[IgorVigor]

I might go and finish job, by performing the bafflectomy...

Is the plate thats removed (the one that I have drilled holes in), mild or stainless steel?

If its mild steel I will mig weld 2 tags on it just incase there is a prob for the MOT.

The part which the holes are drilled in ,which i then chisselled out and then cleaned up the end-hole with a dremmel ,was in a pretty bad shape when i removed mine ,as i cut/chisseled from hole to hole. Theres no way i'd have been able to re-use it.

I found it just as easy making a wee round plate with a tang bent over for fixing ,and a small piece of tubing around an inch long ,welded to the plate to look like the end of a baffle .

[IgorVigor]

I have finished the job

Damn it sounds good after the bafflectomy

Mind you, the sound on the overrun is addictive

Glad I did it

Did have some trouble with the baffle tubes though :S

got them freed by hitting them with a hammer, but the weld broke so couldn't get it out
ended up enlarging the hole it fitted in with a rod and hammer until it would pull out...

Don't know if it makes a difference enlarging that hole?
All I know is my bike finally sounds like its meant too
