REPORT: db Dawg on '04 450F

23 posts in this topic

I ordered a db Dawg for my '04 and it arrived Thurs so I slapped it on and rode around my play track a little bit. First impressions were that it sure pulled hard off the bottom. Next- it's a lot quieter. My wife said so, too. Put the bike up and waited for today.

Today, I went riding at the real track and gave it a good workout. I had a little trouble starting the bike but finally got 'er going. Wanted to foul out just a bit and it blew some smoke once started. Out on the track, I immediately noticed an increased low-end pull. Right off idle, it wants to bog a bit, but once you get past that, it pulls enough that I had to watch my throttle control on our dry track. After say 1/4 to 1/3 throttle, I can't say I noticed any difference in performance and if anything the db Dawg made the bike pull a little harder. We had a stock 450F and 250F and the db Dawg was definitely quieter- my wife said 20-30%. I'd forgotten the little sawed off wrench at home and couldn't do a back to back comparison, but I didn't feel any pressing need at all to remove the thing. By contrast, I put an FMF Q2 on last fall, rode it once, and immediately removed it. I lost low end power big time with that silencer.

So, after 2 h, the db Dawg gets a thumbs-up from me.:bonk::naughty:

Anybody have any sound test results with one installed?......

I don't, but I will work on getting that. I know this much... the sound difference is VERY noticeable at idle.

Are you running the stock pipe? I have a WB Aluminum Pro and can't get the #8003 they recommend to fit.

Let us know when you do. I'm looking for something to quiet mine down. I have to be under 98 db for a trail ride I'm going to this fall.

You'll probably need a spark arrestor, too and the Dawg won't help there.

I don't need the spark arrestor. For some reason they only care about the sound level. :bonk:

I honestly don't know if they will work with a spark arrester or not, but I seriously doubt it.

it will work with a spark arrestor provided that you have:

1) it is removeable

2) the screen goes on the outside/last

3) the screen curves out and not in

could someone perhaps measure how deep theres goes in. I have 2 1/2 inches from the end of my tip to the spark arrestor and am hoping it will fit.

^^^^ I ordered mine today. It was $45 or so from Dirtwerkz. The larger Dawg costs more than the other sizes. I had to get the larger one because of my FMF muffler.
