I'm going to try this method as well by cutting and welding a new tip. I'm quite excited for it
Mod. Stock Exhaust

I did that same mod in september and it works for me I like how it sounds and no problem so far

I thought about doing this exact same thing. I have already done the "5 minute exhaust mod" and was wondering how much more sound I would get by just drilling a few small holes around the perimeter of the weld. Anyone think this would work and sound just as good in conjunction with the "5 min mod"?
I ended up doing the "5 min mod" after some good feedback form other members and I get a better sound at idle but I barely notice any sound difference when riding or revving. I've made the hole as big as I can with the room I have to work with but I'm hesitant to drill any holes on the outside. Every now and then I hear a little kickback when I rev the bike so I'm wary to do any further mods for fear of screwing with the exhaust too much. I would like an even better sound too, but not at the expense of ruining the exhaust or any other part of the bike. Just something to think about SloRider. But I am still open to any thoughts on free mods to improve the sound.

Well I just finished doing the mod and it turned out quite nicely. I went with a 2 5/8 inlet exhaust tip. She's got a decent deep tone to it now and I can actually hear my exhaust while riding even with a helmet on! I'm ready to ride some more an hear it tomorrow! My best friend is gonna ride it so I can see how it sounds off the bike! Def worth doing!
do you know if this mod will void the warranty? anyone?
Probably would be a hassle, but technically if it doesn't cause the problem you bring it in for then it shouldn't be a problem.

This mod is the best thing i have done so far. I love the aggressive sound when bringing the revs up and the mean growl when i let off the throttle. Its a beautiful thing.

Exhaust mod tip
Just did this mod and it sounds GREAT! a nice deep throaty sound but gets loud when you open her up. only costed me 15 bucks for an automotive exhaust tip from the auto store. i chose a 2 1/2 inlet with a 3" output tip.
instead of "shaping" the back end of the tip to fit contour with the cat, i just stuck the edge of the tip inside the cat. also, i cut the tailpipe off inside the cat about 3 inches or so.
changed my mind last minute from running a straight pipe to just changing the tip and couldnt be happier that i did! its loud enough to be heard but tolerable since i commute.
Thanks to all for the great post and ideas!

exhaust mod help!
hey everyone, so i just did an exhaust mod and first of all i want to say i love it! sounds great very loud. however the other day i started it and reved it couple times to show my friends how it sounded and it shut off on me, aswell as i noticed that it is less responsive when i open throttle. has anyone had the same problem? also i welded on a fairly large tip, bigger then anyone ive found on the net so far maybe that could be the reason?? also if anyone knows how to fix it. much help appreciated thanks!!

Did the mod yesterday. 2.5" pipe. Cut away original small diameter pipe to approx. 4" inside the exhaust box.
The result - pretty poor if you ask me. There is definitely a lot of resonance going on. This is where the airflow actually pulses in and out of the exhaust, between firing events, causing resonance within the aft section of the exhaust casing and giving the exhaust a flat sounding, high amplitude sound. To exaggerate, the resonant part of the exhaust sound is somewhat similar to a valveless pulsejet.

A smaller diameter exit pipe would increase the flow velocity and prevent pulsing. Recommend anyone who does this mod limits the pipe size to 2.0", which I think would be perfect.
I'm going to be putting in a 2" flow restrictor within the 2.5" outer pipe to increase flow velocity.

I'm still a little confused on if this will create back pressure problems or make the bike run too lean. And will I lose low or high end torque? Obviously I'm talking about without a PCv or juice box. Any help is appreciated
Most that likely you will loose top end power and if you are way too lean the throttle transition won't be smooth. It's one of those things... you need to do it all or not at all. If you just mod the stock exhaust a bit, it's fine.
The Marthy Danmoto with DBKiller has enough restriction to run safe too.
