I took my LTR to the track last night, and 2 guys I know said they Dynoed one with a cherrybomb and the baffle out. then they put on a Yoshimura slip on and the Dyno didn't improve at all. I'm not sure if they changed the head pipe. Now I'm wondering if should bother spending $$ on a new pipe.

What do you guys think?

u might get 2 hp with ful yosh exhaust system, 2 hp at the wheels!! well it makes a difference...

 

[SandJunkie]

I think it's a waste of time and energy even thinking about it until Fuel releases the results of the shoot out

stritcly from seat of the pants feel, and real life experience.

The gainst you get with the Yosh pipe are well worth the money.

Overrev is where it most noticable. I would bet there is a 4hp peak gain from switching from the stock pipe to the Yosh Full system. The slip on, I dont know.

Never been a big fan of slip ons, if your going to spend the money spend the extra $100 and get the full thing imo.

I have a slip on Yoshi and cb. Thats all I am going to do to the engine. Its fast enough for the woods riding I do. IMO, almost to fast, I dont know if the slip on made a difference in terms of power, vs the exhaust with the baffle out, but it sure looks and sounds alot better. The reason I didnt put on a full system is first off, the full exhaust costs about $480 with a 15% discount from the dealer. And whether you believe it or not, you need a PIM to maximize the power. Thats about $220 with the discount. Total thats about $700. I got my slip on for $318. I think its fast enough. Now, if your riding in sand, thats a different story. But for woods riding which all im doing in Wisconsin. I am happy.

Sand baby...saaaaannnnd...thats why I'm the junkie

Just road with my new full yoshi today, and YES there is a difference, i think a very noticable difference IMO. This thing is now a rocket. Everytime i go to the pit, i sell one of these machines for Suzuki. I should get paid for that. Suzuki. . . ?

 

[SandJunkie]

Yea..and maybe they will give you a title like "CEO of Pit Sales" (CEOPS)?

 

[didntseeitcomin]

I like the sound of the that.^^

i felt quite the difference when i put my full rs-5 on. my buddy has all the same mods as me on his r450 except for the exhaust, however, he weighs 60+ lbs less than me so he used to spank me in side by side drags, but now with the full yosh exhaust i come out a half quad length to a full quad length ahead of him almost every time. not to mention you can just feel the difference in your assometer


and no, you dont need a PIM for the full exhaust. just the cherry bomb will be fine. sure, if you had the PIM you MIGHT be able to suck a tick more power out of your ltr because of the different fuel maps available, but it is not necessary

 

[BCGIrish]

From the A/F results we saw with the CRBM it seems a waste to buy a PIM if your just running an exhaust.

Just installed my pro flo K&N... eeheeemmm! I am running the full RS-5 and just the cherry bomb.. I am still waiting for the ems kit from Yosh.. YES it is worth it.. I came home from the dunes before the install of the intake.. I weigh 225 and am 6'-2".. running 20" 8 paddle haulers and diamond traks on the front.. I was worried about having drop the gearing!! NOPE!! even with my weight. the front end on this bad boy was comming up as I hit the throttle strait up a bowl.. mean power.. more than I had with just the stock exhaust no shooter or lid.. it is worth it!!! I am excited even more now that my intake is installed.. I need my EMS kit. I rode it up the street..WOW! this thing is getting scary. and it sounds meaner than any thumper I have ever heard with the full RS-5 and no sparky and my intake.. it flat out rips.. I love my LTR!

You got a pro flo K & N? Isn't that a Pro Design? Pro Design is still about two weeks away from offering a kit with a K & N filter although they do offer their adaptor with their foam filter. I've seen Trinity (not the greatest products from what I've learned through the grape vine) and have seen a few generic adaptors with K & N filters for sale on Ebay. But Pro Design hasn't released theirs yet. I'm still waiting.....

 

[SandJunkie]

Trinity has their issues to be sure BUT...their products are first class craftsmanship from what I have experienced. They treated me like a king when they found out I was having problems with my controller and they resolved it proto. I really think they got caught in this whole CRBM or not just like everyone else. Seems all the companies are doing the "Foot in mouth" shuffle. I have the ProFlow and it's good stuff. I may even try pulling the airbox completely off next just to see what MY ass-o-meter tells me.

 

[Baracudaaa]

I just got the Yoshi PIM, with that on their full exhaust and a trinity proflo, i will need to start doing arm workouts to keep from being thrown off the back of the quad, its freakin explosive.

 

[kheft]

If you think about it, a slip-on is almost the same thing as the stock exhaust with the baffle out on the LTR.

 

[LTurboR450]

not really, the yosh rs-5 muffler is a straight through "glass-pack" design. the stock one as i have come to believe is chambered and certainly is not straight through. they both weigh a ton tho, i wouldnt mind titanium instead of steel

 

[Freeflow]

might be on annother thread, and this is going off-topic, but you guys mention that you are putting in K&N/Trinity/Prodesign Filters. So, where can i look at the Trinity/Pro Design/K&N air filters?

Where to buy?

All the guys i ask, say it is not available?

What about the K&N airbox lid?
