pipe

One of mine came with a DG system. After hearing how much the DG systems suck I jumped on a buy it now FMF system for $117 shipped. Looking very forward to getting the POS DG off and the FMF on. With the FMF my stock Blaster felt weaker bottom to top. I was running a 280 main, K&N filter with no lid at 1600' ASL. Here is a thread I started asking for people who had tested a DG back to back with other systems http://www.blasterforum.com/exhaust-137/who-has-used-dg-exhaust-system-49920/
I thought as much DG bashing I've seen here that some of the bashers would have had at least used rode a DG. The couple that did post had positive things to say and the guy who set his system on fire to clean it out probably had problems that no exhaust system would have cured. There is no way I would pay the new price I see the DG's listed for on ebay but with a full DG and a full FMF system laying there to choose from, I'm happy with the DG.

This is the same as the old "Cast pistons suck,and forged pistons are the ultimate" argument!

Give me a freekin break! I run and prefer a cast pist ANY DAY over a forged,because they have many advantages,one is MAKING MORE POWER.
Another would be much more quiet! I'm not trying to bring up the old piston argument,but using it as a metaphor for the "DG pipes suck" argument.

This is the same thing as saying that "Toomey B1's are the ultimate system and everything else sucks". They're a great system,well built too,but not the ultimate weapon. Everything works (or must mork) with all the other parts to create power.

I believe that all the negative reviews that I've seen about the DG blaster system most likely could be attributed to it NOT BEING SET UP CORRECTLY,AND PROPERLY JETTED. You can't just bolt on the DG,not change jets,not increase air flow,and stick the cool DG sticker on your ride and expect it to work properly. Thats kid stuff. Proper tuning is the key!!!

I would love to give a DG system (a complete system) a try on my blaster with the porting,case mod,and re-chamber head,etc I run. and give you an "HONEST" review/write up. If the DG system sucks so bad, how about somebody just GIVE ME THE ONE THEY HAVE,and I'll pay the shipping,because if its that bad,you shouldn't want to keep it anyway. Thats how I look at it. Anybody have one they want to "Give" to me?
 
I always suggest Toomey. I've ridden my friend's FMF blaster and I can definitely say my toomey whoops it the entire way around. Very low end might be slightly better on FMF, but everything else is much better on my Toomey. Only two I've ever really got the chance to compare, but I don't regret the pipe at all. Plus the sound... mmm...
 
I have had or rode on nearly every blaster pipe out there. Every engine was of a different tune level but there are some general trends to be noted. Paul Turner and DMC notable are exceptions I have never rode on either of those.

First thing to note is that *GENERALLY* pipes are a trade-off. They are tuned for a specific situation where they are most efficient and generally "drop off" anywhere else. Some pipes drop off more than others! Some pipes have certain limitations that others do not.

I have a DG pipe on a blaster sitting in my back yard right now. It has a rpm ceiling on it that some other pipes do not. You cannot simply "turn it harder" to get more power like you can some others. This leads to the rumor that DG pipes suck. They basically have the same rpm powerband that stock pipe has and anything above their tuned range and they fall FLAT as a pancake.

If you plan on building a naturally rpm limited engine. A "woods" engine would be an example. Two great choices exist. A FMF Gnarly and a DG type II. Both have good bottom end but have a low peak hp rpm and no over rev.

There are a LOT of good "middle of the pack" type pipes. A few examples include the FMF Gold Fatty, Pro Circuit Platinum, DMC alien (as I understand it), and the Paul Turner mid rev (as I understand it). These pipes increase the tuned rpm range slightly without losing any bottom end. They don't necessarily increase the bottom end torque of the motor much. They're good for general trails on stock or mild motors.

There are a few pipes that raise the rpm range of the powerband but also greatly augment the bottom end (the best combination for general use, really!). A few are the Dynoport right bend (also no personal experience ON a quad equipped with that pipe, only rode with someone who had one), the CPI BBK pipe, and the Toomey B1 kit. These are really useful when the engine has already been built around it for higher rpm's (porting and head work) but you want an increase in bottom end for tight tracks, heavy woods, and general playing around.

Then there are the "top end" pipes. Most of the top end pipes are going to be drag only options with one notable exception. You've got the unsilenced OOF (out of frame) drag pipes, RDZ, and shearer. Shearer also makes a silenced version of their pipe. The notable exception is the Power pros, F7, CT racing (a rose by any other name would smell as sweet) pipe kit. So far I haven't found an rpm range, tune level, or displacement that wouldn't work on it. Some will argue that it doesn't lose any bottom end but I believe that has more to do with engine tune level than the pipe itself. The trick with the PP/F7/CT is that if you have the portwork, carburetor, airbox, head mod, stroke, and displacement to run it.... it basically never stops pulling. While this may sound like a resounding endorsement for the pipe BE WARNED! It's a PITA to install and take off, I've seen some quality issues with some of them (holy welds), and you really need a built engine to extract the most out of them. I have one sitting on the shelf out in the garage and am running the CPI BBK pipe instead (no I won't sell it, don't ask). I like the way the F7 pulls, but it's SOOOOO hard to work around/with I'd rather have the CPI.
 
^^ i dont have a DG pipe anymore.

BUTT we had one at the shop for a good couple months and i got to try it on a bone stock blaster. even better we had removed the dg over some time and reinstalled the stock and drove that for abit aswell so i got a good feeling of the changes the dg made. WITH the dg pipe we ended up with a 260 main jet on the stock motor.

The hate on for DG is THE ALL TIME BIGGEST BAND WAGON jump-on on this intire site. The majority of the people that bash it are people that hurd it sucked.

the people that say it sucked are the ones that "cheaped" out on the expensive pipe and got the lower budget DG in the first place. there also the same guy that will most likely "cheap" out on any other fact of making power with that great pipe. maybe even cheap out on jets.........

EVERYTIME i hear it i honestly laugh to myself. Think of it this way...... honestly i cant recall anyone even useing a dg and a rechambered head togeather.

When looking at the dg the expansion chamber it opend and closes in sooner and tighter aswell the stinger pipe is longer. (compairing to a fmf fatty) The expansion part is the same size around at its fattest point but tappers much sharper then an fmf.

JUST looking at the pipe it kinda shows the pipe is designed for a much more sharp and low/mid rpm. with such sharp tapers it will tend to make the "Power band" in a more narrow form, unlike a pipe like the fmf fatty which is designed to give a MUCH FATTER powerband.

The people that bash it unknowingly are just showing there lack of experience in understanding how something works......

it REALLY annoyed me after testing the dg, it worked MUCH better then stock.....

I have a DG pipe kit on a trail ported blaster with a rechambered head and 22" dirt devil II tires on it. Super noober rode on it last weekend at busco. It had GREAT bottom end but falls flat trying to overrev.

What limits the DG system is the headpipe diameter and length. It's small and remains small for a ways which limits head pipe charge storage. It pulls good at lower rpms's but it just runs out of steam early.

The "rumors" are sometimes rumors and sometimes grounded in fact. The DG pipe system has a limited rpm range for strong power centered on the "bottom end".
 
YI dont gather, why anyone would bash anything. Unless it is truly a defective product and bad.


I had a used one, that I sold. I never used it. But did manage to do some searching elsewhere and found that the DG basically gave more low in to mid power.

Alot of the other pipes are geared towards mid and top end.

To me, its preference.

My DG system isn't defective at all. In fact, the silencer is quite well built.

The "trouble" with that system is that the easiest way to increase overall hp is to raise the rpm ceiling of the engine. A pipe that limits the over-rev limits the overall horsepower available from a given engine.

If you are looking for a pipe that will give good low end (woods engine) then the DG isn't a bad choice. Just don't expect a screamer engine with it installed!

The trouble is, people expect everything out of everything. A pipe kit that gives GREAT bottom end isn't going to have the best top end. People think that because someone wants to get their engine built for higher rpm's and wants to sell off their DG pipe that they can't be as good as what that person is buying.

The needs are just DIFFERENT. Not better or worse....

OK i did noticed the good low end the pipe gave and how it seemed to pull hardest in around mid range. the bike did seem to level off on power through the higher rpms but i figured it was due to the stock motor. i see how it would die up top tho, not much of a band.

it would be neat to have a motor for all out low/mid power.
 
I love my toomey it absolutely flies on the trails but I also have a set of Boyesen PSR reeds a 30 mm carb and a no air box pod filter.on it so quad to quad preformance is going to differ some. but I would definatly buy it again if I had to.
PS the Toomey and FMF are the same performance wise .except the toomey has more down low and much more up top than the FMF does. But I use a fmf fatty and turbine core2 on my other blaster so I know from exp. If you want to see the dyno power graph lemmie know and I'll post it for ya ok.
Here's a link to show you different pipes ok

When I first got the blaster it had a DG pipe system. Compare that with the toomey/powerpros no comparison! I would save a little more and get yourself a better pipe for the type of riding you do! My toomey hits much earlier than the right bend i had and stays there to the top, the rightbend hit later but winded up more! I choose the toomey as i'm on trails 99% of the time and it works best for me!

BTW- Cherry kool-aid is my favorite!
