Well if you do take it off, it would only be short term, I wouldn't do it for more than a two week period and that is stretching it, you would need to do a TPS reset, you will lose an assload of low end torque...
Oh and it will sound nothing like the Jardine...
The reason each pipe has a distinctive sound is because of they way their internals are built, the inside dimensions, exhaust material, the bend in the pipe that leads from header to the muffler, packed or not packed, etc...
I would have to bust out all the relevant theories on fluid and sound dynamics to explain it all and even then neither of us would fully understand it anyway.
Altogether not a good idea.
Keep in mind with the Jardine you will have to repack it every so often. I think someone on here knows however many miles it is, but I don't.
The Remus Exhaust sounds pretty wicked but it is even more expensive, at least in the short term. Remus doesn't have to be repacked.
