I have a '99 Lakota for my girlfriend or friends to ride with me that is currently all stock. I am planning on removing the intake snorkel and installing a UNI stock replacement filter (not the pod style). I was also thinking of rejetting with the Dynojet kit which, I understand, should help power-wise.

My question is: If I do all of the above items, is it really worth spending the money for the SuperTrapp IDS2 exhaust? I realize that a more open exhaust will help for power but it is REALLY worth the money spent? I just want to give it a little more power because it almost made it some of the steeper hills at the sand dunes (Silver Lake Sand Dunes in Michigan) but couldn't quite make it. Most of the areas it is ridden is on trails with an occasional trip to the dunes.

I just want to justify spending the money on exhaust since this is just my "other" quad. I just bought a 2000 Bombardier DS650 as "my ride". [img]i/expressions/face-icon-small-smile.gif[/img]

Most aftermarket pipes/exhaust systems that I tried improved the top speed but lost some bottom end power. So, it all depends what kind of riding style you would have on that Lakota.

 

I guess I would really be more interested in bottem end power than top speed. I am not planning on racing. It is just recreational.

Do you have a Lakota or are you just stating what you have experienced with other makes/models? I am just curious. I would like to have some people reply that actually have a Lakota with the SuperTrapp IDS2 pipe that can give me an idea of the power difference before and after the change of the pipe only.

 

I started this thread because I really don't want to throw $250 into the Lakota for the IDS2 exhaust if I am not really going to feel a somewhat substantial "seat of the pants" difference.

Do you think it would be worthwhile going with the UNI factory style filter and do a rejet with the Dynojet kit regardless of whether or not I get the exhaust? I just got done taking the intake snorkel off tonight. It doesn't get ridden in deep mud or water anyway.

 

No, I don't have any modding experience with Lakota. But I've ridden my buddy's 2000 Lakota (blue?) that had 5-speed semi-auto clutch, air-cooled engine quite a few times.

 

Did he have any mods done to it?

 

Nope. It was a bone stock but I thought it was fairly good ride for what it was. If I were you, I will just keep it stock and just take good care of it. If you are really into sport riding, you need to get on today's hi-perf EFI water cooled 450s. More power, lighter weight and awesome handling. And tons of aftermarket parts including ECU programmer - a lot easier and quicker to adust the fuel/air ratio than carb jets and needles.

 

Anybody else have any input?

 

I like the IDS2 for ease of power/sound tuning (remove,add discs) and it makes good power even on a stock motor, have one on my son's 300ex, but the quality of the muffler is less than I would expect for a brand name like Supertrapp. The core is almost impossible to remove for repacking, you have to heat the silencer body with a torch and pound out the core with a wooden block,damaging the core somewhat. Also, the tiny little collars they barely tack weld in to hold the screws for the discs break off very easy, if the muffler is run a while without removing and putting anitsieze on the bolts on a regular basis, I have had to make little steel plates, drill and tap them for the bolts, and weld them into place. After recently repacking the IDS2 last week, I am done with that muffler, next time it gets sold or scrapped for an easier to work on system. But to answer your question (finally) a good aftermarket exhaust along with jetting and a filter, will give you the needed grunt to top that dune, when compared to stock.

 

Well, I think I have decided against the SuperTrapp IDS2 for now only. I was considering it because rockymountainatv.com has one left on clearance for $229.99. It seems like a good deal for a full aftermarket exhaust but I have read mixed opinions about the power gains on a Lakota.

If I do decide to go with an exhaust, I may end up spending the extra money and get the Big Gun exhaust.

I just don't want to throw $250-$350 into the Lakota (which is for others to ride, not me) just so it sounds good. To justify an exhaust, I need an obvious "seat of the pants" gain.

I had already found that the Lakota ran in the sand better with the dirt tires than paddle tires. It just doesn't have the power to turn the paddles up steeper hills. The dirt tires spin more but they keep the RPM's up which allows it to climb hills that were a problem with paddles.
