I did it. Cored them out. They sound awesome, but they are freakin' LOUD! So loud that I think they will piss off the neighbors. But I could definitely feel that the bike had more power, even without switching to Map2. I bought a set of stock cans and cored them so I would still have my originals in tact. I have since switched back to my originals while I decide if I want to go with the cores or not. I took Scott2Ride's advice and went with a tapered core. I also used blanket style packing. They really do sound good.

That's what I was afraid of, too loud. I was looking into the cored can route but it looks like I'll have to shell out a few more $$ for some slip-ons, probably arrow.

Maybe I'll core my stock cans for track use....

How long did it take you to core out the pipes?

I took me about 4 hours to do the set. The toughest part is getting the cats out.

They are definitely loud. I was afraid of the same thing, that's why I din't want to do it to my original cans. I think I'm going to go the same route. I've only got about $250 in the cored set, so no big deal. I think I'm going to go with the Akrapovics though.

Initially thought they were too loud. But The packing was just too loose. It was getting blown out. Then I went back and re-packed with the material I used before and the thin blanket that came in the stock can. That toned down a lot of the metallic ring. My head stopped ringing after that. It sounds real "mean" :fangs: , but not what I was looking for. My 2 valve Monster had a better sound with the Carbon Arrows that I put on it. I know that I can't get the same sound from the RSVR. That's ok. I am waiting on some Akrapovics Titaniums! I would have gone with carbon but felt like it wouldn't hold up to the Rotax. Carbon was ok on the Monster it only put out 63 hp. I also wanted something quieter this time around. The ringing in my ears reminded me that my hearing is important too.

BTW - I always wear earplugs, my Aria Quantum F is just plain noisy.

:peace:

I can't take a pic of the core since I've alread installed it. Basically I had the inlet end rolled to 2 13/16" and the outlet end rolled to 2", which resulted in a gradual taper. At the outlet end you can barely see the packing blanket. I will say though that the bike felt like it ran great even with Map1. It did run a little hotter, which I guess means it was a little lean.

What about the cored pipes without the taper?

Whats the difference performance & noise wise?

Forget the neighbours. You wont be there long if you are going for a ride, and if all you are doing is reving it in the drive then you deserve to be hated :D

But you soon get used to the noise, and you should ride with ear plugs anyway!

Plus everyone will love the sound!

Thats ok then, mine is only out during the day. No early starts or late nights. Shouldn't be too much of a problem.

Now if this guy would just get his arse in gear and get them welded up... aargh.

Like Scott said, they do sound awesome. I tapered mine after I read one of his previous posts that recommended it. Something about giving the bike a little more back pressure which smoothed it out.
