Wileyco Exhaust Site

Has anyone tried their system?

It's a true dual system from each exhaust port out of the head into it's own header and into its own silencer. And the silencers are side by side where the stock one mounts now. It looks pretty sick.

From what I read, it makes 42.4 HP and 60.3 TQ. I wonder if the artcile meant to say 52.4HP?

Either way, has anyone tried it, or know anything about it, like price or where to buy?

Thanks....

 

That is the exhaust that the Polaris dealer here in Dubai stocks. I have rode a 03 Pred with that exhaust, and it did not feel like it was putting that much power out, to be fair I do not think the guy had it jetted properly either. Compared to what mine feels like with the HMF, mine pulled harder and the guy liked the way mine felt too over his (only mods at the time for both where pipe, K&N, and 38 tooth rear). We didn't line them up cuz this was at the dealer, and they only have a small parking lot. The Polaris dealer has been selling those Wileyco's for over a year and they don't sell very well, look nice though, and go for almost $600 here. The sopund is somewhere in between the Pure pipe and the HMF for loudness, and then it has kind of an off beat rumble to it. I will have to go and see if they have one with the dual set up in the garage and take some pics. I had asked about this exhaust a few months back and no one had heard of it, so I guess they are finally getting around in the US now.

Thanks Chris

 

Chris, thanks for the great info and first hand experience. It sounds like, even if jetted properly, it won't be far off from the HMF. I asked a few months back about the best available exhaust for this bike, and everyone pretty much pointed towards the HMF model. I just saw the Wileyco one this week after looking through a mag and was curious, but I have a feeling I don't need the extra weight, as this thing already weighs a bundle over the newer 450 quads out there....you know...

I have the White Bros one now, and have been pondering on whether or not to buy a replacement to make more power, and whether or not I'll even notice the difference?

Do you know if there was any real improvement with the HMF header, as compared to running stock headers and just a slip on HMF?

Are most people running the sport series HMF, there's quite a few different HMF slip ons, so just wondering.

Sweetquads: I didn't notice a dual system on your site for the predator (just the HMF/DMC). Did you have a link? Thanks.

 

03 Predator,

I can't find the graph for the full system dyno from HMF, but if I remember correctly the full system got 2-3hp and 4ft#'s more over just the slip-on. I got the full system (sport series) and am not runnig a quite core, no laws for sound levels here and IMHO it is the best thing out there. I think the duels Tom (SweetQuads) is reffering to are the LTE's.

 

Chris, very nice dual kit, at least looks wise.

I think for the $ amount, and level of power increase, the HMF full is the way to go.

I'll need to fit that into the budget.....should be worth it.

Appreciate the experience with these, Ryan [img]i/expressions/face-icon-small-cool.gif[/img]
