Jardine Exhaust Mod

Alright, this is it! The Jardine tapered exhaust mod.
I already have Jardine pipes, I just thought they could be louder, so I tried this and it worked great! The baffled area of the pipe works like a resonating chamber and adds a slightly deeper tone to the exhaust note compared to just a strait pipe.
When dealing with a tapered exhaust you just can’t take a holesaw and do your thing.
First you have to modify the holesaw bit, I used a 1 3/4 inch bit then had it lengthened, (Pics 1, 2 & 3) because the baffles on a Jardine pipe are attached deep on the inside too, about 14 inches into the pipe. I can’t weld worth a shit so modifying the holesaw wasn’t easy. I had to search for a while to find a machine shop that was willing to do the work, (they worried a bout getting it centered and balance properly) but luckily I found Giovanini’s. And it only cost 10 bucks!
$14 for the holesaw bit, and $10 to modify it + 1 1/2 hours (if by yourself and you take your time) = Cool Mod. :thumb:

I have a dB meter ordered, so I'll have readings posted next week.

I DO NOT recommend this mod for states where your bike is inspected.

Step one – Remove the pipes from the bike, this isn’t something I recommend you do with them still on.
Step two – Take and drill out the baffle, you have to go slow, these bits cut metal best at a medium speed. Don’t push because once you break through you have another to cut on the inside. Be really careful not to push on the last one or you’ll go through the end of the pipe, and that’s a bad thing.
Step three – Remove the baffle from the pipe, and then tip the pipe on end to remove any shavings.
Step four – Repeat steps one through three for the second pipe.
Step five – Put you exhaust back on your bike.
Step six – Enjoy the loudness!

This is the same as running strait pipes so don’t forget to re-jet your carbs.

I recomend 135 & 138 main jets, but I have to ask first...
What kind of bike do you have? and do you notice any performance problems?
Like a hesitation in the trottle, or a noticable backfire?

Oh, and before I forget....

That is a great Holesaw Mod..I want to do that mod myself.. the Holesaw I have has a 18" extention. but the saw itself needs the 18" extension at least a 8" one..

Now that you mention it that picture does look a bit out of proportion. It is actually the same size as the GP-1 pictured above. This one is just polished to give it a chrome look.

I dont suppose you would be willing to trade for a clean factory exhaust that has the end baffle removed, would you?
