I am toying with buying either of the above but can't narrow it down. Big Gun make a quiet series but I cannot find any reviews on it. Can anyone tell me how often the Big Gun and Supertrapp quiet series need repacking. I like the idea of the pro duro because it doesn't need repacking but I'm not sure about the performance gains, again because I can't find reviews on it. Any comments on the above from owners regarding performance and rejetting would be appreciated. Andy.

I think you'll find most put the Pro Duro at the top of list of aftermarket exhausts. See Devon's recent post on his FrankenTrapp. It looks cool and is not much louder then stock, a very important consideration. Performance gains are minimal with any of them. There was a new pipe on the market that offered monster HP gains, something like a 1000% boost. But I think he's in the counterfeit Barbie doll business now.

I have the Big Gun Quiet series complete system. Perfect fit, excellent quality, nice sound. It has been on my bike for 1500 miles and sounds the same as when I installed it. As for performance of the top three, not really sure. Mine has jet kit with 155 main jet, idle mixture screw turned out two turns, air box opened up. It gets an average of 45mpg and will out run any stock KLR. John A17 R1100GS

I have the Big Gun race series, and I love it, you can feel the gain over stock and over the quiet series. BUT! With the race series you need to think about this. It's loud really loud like HD loud, I have a buddy that is a ex HD rider and he told me my pipe hurts his eyes when riding with me, it's as bad as a HD with open pipes, and I have the ticket to show for it.. And you will need to repack it or you will blow the can out. I got the quiet series kit for it and it was not as loud and that was the only part I was happy with, with the quiet series. But after about 1,000 miles I found that the can blow apart and could not find out why it did and Mike from Big Gun took care of it and I'm back to a race series pipe now. I have a 4k trip I'm going on friday and I will be thinking about this pipe every mile, will it blow, will I get more tickets, and what about all the people around me that will get pissed off cuz I'm way to loud, and can I really take it off road, I can but I will only mess it up for others that are not as loud as I am and that is not the right thing to do. If I had to do it all over I would of keep the stock pipe on and just lived with it as it was. As it is I put far to much money into this pipe then I care to and I don't have the stock to put back on. Is the Pro Duro any better, I'll never know unless one falls out of the sky.. Buy a 420 shock and some springs for your bike, in the end you will be happer..... Tammy...... *********** REPLY SEPARATOR ***********

Does that even have a spark arrestor? Devon -- "It's a troublesome world, all the people who are in it, are troubled with troubles almost every minute" Dr. Seuss

Yes it does, but that does not take away from it being tooooo loud..... Tammy *********** REPLY SEPARATOR ***********

The Big Gun Race Series is loud enough to make Jesus cry. The BG Quiet series has a spark arresroe, and sounds like a stock exhaust with an exhaust leak IMHO. Is it just me or can other people hear the "tweet" in that thing? Supertrapps seem to last and aren't super loud. Pro Duro's are super quiet and sound fine, passed every spark arrestor test at every AMA DS ride I've taken it to. If you absolutely have to waste money on an exhaust, go ProDuro. You'd be much happier spending the money on improving the suspension, like Tammy said. Having owned 2 Big Gun exhausts (Race can exploded and got a Quiet Series at a deep discount as a replacement, which later shit its pants too) and a Laser, I hope I can make a halfway informed contribution to your question. As far as engine performance gains, it's a KLR, man! The only real engine performance boost for a KLR is to sell it and buy an XR650R. CA Stu ;-)

I had every intention on buying the race Big gun pipe, UNTIL I asked this list and some other folks about it and decided that although I do like loud, I don't want ridiculous either. Then I found out about the cans falling apart and the packing blowing out. I chose the Pro Duro Race version and here is my thoughts on it after 4500 miles in 3 months time: 1. When I got it and opened it up, I was very very pleased with the way it looked. (see mrmoose's pics under the photo link on the lists main page) Not only did the pipe look great in all its shiny stainless steel glory, but the hardware was top notch too. As a nice touch, they also send you a MUCH beefier heat shield to mount on your plastic to replace the stock thin one. Both the metal foil and the soft body of their heat sheild is stiffer and thicker. 2. When I first fired up the bike in the garage, I could not believe how quiet is was just sitting there idling. You can just look right through the can, but it just sits there, softly loping along with a single cylinder putt putt putt putt. 3. When I pushed it outside and gave the throttle some little blips, to maybe around 2200-2500 rpm, the motor gave out a little louder BARK that got me thinking "ahhhhh, this sounds nice". 4. When I gave it a good wide open whack to about 4500 rpm +, it has a much meaner bark and growl that got my soul stirring, but again, I could not believe just how tame the sound was. After riding it for a while and getting used to it I now feel that the sound is just perfect. You can actually "adjust the sound" with the throttle as you ride. Its loud enough to hear it when I'm going down the road with earplugs in and fullface on, to hear a nice bark when I blip the throttle, and sounds mean and killer when I open it up all the way either parked or when I'm slamming all the gears to redline flying through the twisties. But its never really loud. Its also quiet enough at idle (not much louder than stock), at cruising speeds for miles and miles (you don't get tired of hearing it at all), and you can easily "sneek" around your neighbors even if its at 1:00 in the morning, just don't give it the gas hard and you will not be much louder than stock. In 4500 miles, I think it got just a touch louder while it settled into the bike and broke in and then that was it. It has not changed tone or note or loudness at all. It has not vibrated loose and it still looks just as good as new. The "s" shaped piece that mounts between the tail pipe and header has turned gold a bit, but you can't really see that part much anyway. There are just 2 cheap pieces that you need to buy in addition to the exhaust, and they are mentioned to you in the very thorough instructions that someone has posted online. (I forget who did them, but just ask the list) As far as power gains go, like someone already mentioned, its a KLR. Spend big bucks in the suspension to go fast as hell in the turns, beating every sportbike rider you come up on, and scraping the side soles of your boots off,(like I do often now) and you will think you have a crapload of power, and so will everyone else. (I have people come up to me and ask "what the heck I did to my motor" when they try to keep up with me in the twisties) I got some power increases, however they were not much, but it is noticable and I like it. I did take alot of time adjusting the mixture to get it right, and I am still working on it a little at a time. Thats one of the reasons I like the Pro Duro so much, because after spending so much time and energy to get it all just perfect, I want it to stay that way, and if your exhaust is blowing out and falling apart, your mixture will be changing all the time, for the worse. With the Pro Duro race, K&N filter, airbox "L" cutout, screen removed mixture screw out 2 turns, K&N jet kit with 150 main(I am going to try the 145 main next, it keeps getting better the more I lean it out from what K&N says to do)and the clip in the number 2 position, I am getting 49 mpg when I ride it hard hard hard in the twisties, and 51 mpg just cruising down the freeway and doing errands and such. I do not go on reserve till 245 miles! and can go 300 miles on 1 tank! I love it. MrMoose A8 (Barbie and Ken special)

PS Tammy, if you're planning a 4k mile ride with a Big Gun pipe, pack lots

>of earplugs or learn to lip read

I don't mind the sound at all, having had a Ska Punk and Oi! record lable doing shows 2 times a week with a 2900 watt system and 300+ kids running around for 8 hr's at a time the Big Gun race pipe is really not that loud at all.... Tammy.. BTW I have the new can Big Gun is making now and it's 100% better and would be at home on a KLX 650R
