Louder Exhaust

[sam_cg_cook]

Hi.

I have a Jardine 4-1 megaphone exhaust.

I would like it louder than it is... any suggestions?


Thanks.

i have a 4-1 kerker on my xj. it has a removeable cone at the back side. it has no packing in it. it is real loud when you crack the throtle. not sure about jardine,might have same removeable set up.

when my stock exhaust was about dead
in order to balence the back pressure
I took and drilled about 6 to 8 holes in a circle at the
end of the megaphone on each side
made a difference in sound
but didn't make it thru an inspection
but it did get me thru a season

My old 4-1 pipes I got from JCW over a decade ago(they no longer sell them for the XS11) had a rather tinny sound. They only had a crimped baffle pipe welded to the the end of the megaphone seal plate, and it could be removed by unbolting it. There was NO glass packing, etc inside the megaphone. I drilled only 4 1/4" diameter holes in the megaphone seal plate and it gave it a nicer deeper throat. And, if I have any problems or concerns about inspection, since I can remove the plate to get access to both sides of it, I can either screw in some sheet metal screws into the holes, or put some simple nut/bolt combos to "temporarily" seal the holes until after it passes, then just remove them to get the sound back!!

T.C. 'ping,ping,....er...I mean.....VROOM, VROOM!!

The Jardine 4-1 has a cone baffle on the end that can be removed for louder sound. Mine is attached by two pop rivets side by side at the bottom. Just drill those out, it's only a friction fit on the other side. The rivets on mine worked loose enough that it occasionally blows out when I really crack the throttle.

Robert,

How does it sound without that cone baffle?

I've ran The Dark Horse with the baffle removed for short periods of time. (Sounds like a race car in my garage. ) I've not ran it on the road that way. I had concerns about performance problems or burning exhaust valves, etc. by doing this.

What do you XS Guru's say about this?

It's a louder/deeper rumble. Ususally the way I find out the baffle has come off is that I'll notice that the engine is sounding particularly "bad ass". When I look at the exhaust, sure enough the baffle is hanging off. I like that sound, that's why I went to a 4-1 header from the stock pipes. But since the baffle finishes the end of the pipe, I choose the looks with it on over the sound with it off.

Thanks... I think that I'll go for the sound.

Why would anyone want it louder????

So the 94 year old white hair with the broken hearing air in the land yacht in the lane to your right that is about to turn left might just notice you,

In addition to enjoying the aural sensation of combustion/power, it can also be safer. My stock pipes are so quiet I have had people in cars and even bikes tell me that they didn't know I was there as I pulled up next to them. A louder pipe can give warning (esp. to cages) that you are nearby so they can be watching out for you. Hence the expression "loud pipes save lives". The quicker the bike the more important this can be, and our bikes are quick.

I won't argue the pros and cons of noisy pipes ( it's like a helment or oil thread) but I will say I believe loud pipes piss off more people than they impress. That said I have ridden daily since 1965 and have never wanted to impair my hearing or comfort while riding. My thoughts on the matter.
