    I discovered the post by JTG on VFR Discussion that detailed the partial gut modification:

    A New Way To Gut Your 6th Gen Exhaust - VFR Discussion

    It was very easy to do and like so many others, I'm totally pleased with this practical man's ( poor man's ) exhaust mod. The bike went from singer sewing machine to deep throat, for the cost of about $30 in dremel cutting wheels and an 1 1/2" diameter hole cutter.

    It may just be my imagination but my first ride after the mod felt like there was some new found low end grunt that was not there before. Anyway, totally pleased with this Sunday afternoon modification.

    The most tedious part was re inserting the heat shields onto the cans which was just an alignment issue. It's not too loud at all but definitely an improvement over the stock exhaust note.

    Can you post a link to the thread you're talking about? Did you have to cut the cans and weld them back together? I was wanting to do my exhaust but didn't want to have to cut the cans....looking for more of the "proctologist's approach"...you know....all work from the outlet hole :)

    Looks and sounds like a project I'm going to need to try. I've got a couple days off of work after Christmas....may just have to knock it out then. Thanks for posting it! I can't justify the money of doing aftermarket exhaust but I want to get some good sound....this seems like the perfect compromise.

    worked perfectly fine for me. Try a different browser, it may not like the one you're using. I'm using Google Chrome.

    Loud exhausts are not condusive to urban living and turn you into an insane pillock playing tunes like Satchmo on your can.

    Hey Motoman, there was no can cutting at all with this mod. More like dentistry with the dremel tool. Eye protection is a must and I'd recommend a dust mask as well.

    I agree. That is why I live out in the middle of nowhere.

    Step 1-drilling around the tips

    Step 2-Cutting the tips off

    Step 3-Cutting internal pipes out. They use a dremel. I pushed them to the side and stuck a sawzall inside and cut them off.

    Step 4-what it looks like

    I cut of the ends and ripped the guts out and then had them tig welded back on. took me about 20 mins and it looks so clean you cant even tell I cut them off.one thing I really like is I still have the little end pipes on there so the flashy end caps don't get all carbon and black..

    I got my exhaust done last weekend and all I can say is WOW...what an amazing sound!!! I did it slightly different and think that it made it a little easier and faster. First, I didn't take the exhaust all the way off the bike. I loosened the mid-pipe clamp and took out the silencer mounting bolts and let the silencers drop down pivoting on the clamp. The crossover to the left silencer rests on top of the rear tire...this gives you a secure holding for the exhaust so you don't have to fight with holding it on a bench while doing your cutting. I then took off the dress rings and heat shields from the silencers, cut around the tips with a 1 1/2" hole saw and cut off the ends of the tips with a sawzall just as described above; by this time I'm only 20 minutes into the job. Now the hard part....cutting through the pipe from the inside with the dremel. Unfortunately it took til I was half way through the 3rd tailpipe and 25 cutting disks before I figured out the trick :crazy: OK, here's the trick. When I cut all the way through the pipe with the dremel disc and continued to cut the pipe, the discs would wear down very quickly. So...I took the dremel and basically just "scored" the pipe (cut almost all the way through but not fully through the pipe) and then took a small prybar and simply snapped the pipe off. By this time I'm 1.5 hours into the project. By using this "scoring" technique on the 4th and last pipe, it took less than 5 minutes to get the pipe cut...man, wish I would have found this out sooner :) But, since I did, I wanted to pass it on to anyone who might be doing this in the future. Then I shined everything up, filed all the cuts and remounted the pipes...2 hours and I'm done. I started it up and my mouth dropped in amazement! The best thing I can compare the sound to is a Mustang GT with FloMaster exhaust....absolutely AMAZING. Then I took it on a ride. maybe it's all in my head but I felt more low end power around 4000 RPM and a smoother transition in the V-tec.

    Can't thank 07VFRVince enough for posting this...I was ready to cut the can and do the weld type gut and this was much cheaper and quicker! Anyone thinking about doing this mod, I can't say anything bad about it...it's awesome!

    Good job, I think I went through about 50 or so disc on the dremel. Sounds AWESOME-- Love it.I had a Valasco slip on on my 84 750 Interceptor and kind of brings back those sound memories.

    How would you say the volume compares: lots louder or just a bit?

    It's quite a bit loader but nothing obnoxious. It's a nice deep throaty sound...I love it!

    So glad I did the gut. Sounds like a muscle car, throaty,not like a sewing machine anymore . Now I can actually hear my bike when riding with my Harley friends. Seems like all my buddies are leaning towards the dark side , guess thats what happens to most with age. NOT ME. :)

    I didn't have a choice on my exhaust because it was already gutted when I bought my VFR. I thought the sound was normal because I've never heard the stock exhaust. Now I sorta wish my exhaust was stock. Riding at cruise speeds the tone is noticeable but not bad. But, riding around town and at idle, It sounds like I'm riding a dragster. It is a little annoying. I'm sure folks behind me find it REAL annoying.

    It may have been totally gutted. It does look pretty empty inside the can. The engine runs as smooth as silk. And it does have a Power Commander installed. I don't know if this has anything to do with the engine performance.

    Damn, I may have to do this come spring. My previous bike was a 750 Vulcan with aftermarket pipes, and it was that way: deep rumble, but not loud enough to be a problem. And yeah, I loved that sound.
