Pipes


Yamanewf. I ran Aaens on my 600 sx for one season and thought they added great power. I kept reading about that same pipes over and over again, Bender this, PI End Dump that. I ended up finding a set of PI End Dumps and I'll tell ya that over the Aaens there is a huge difference. Between the two pipes top end was about the same, the Aaens do well there and they also sounded a little more trail friendly being just a little louder than stock. The PI End Dumps not only had the same top end as the Aaens which was a decent top end #, but they pulled WAY harder. Definetly made the sled more fun to ride. That's the reason the Aaens are so low, just the power curve.

The PI End dumps are stupid loud though. Sound amazing at first but you get tired of the noise real fast... at least I did anyway. Good thing I bought one of the 3 into 1 silencers with them!!! Sounded about the same as the Aaens did then.

The great thing about the aaens is the really light weight, lower sound, and great gas mileage when properly setup. But yes they don't have the strongest bottom end, but top end is great.
 
What about SLP's, do they make good power?I like the fact of the canister silencer for lower sound levels.How far behind the PI's and Benders are they in bottom and mid range pull.Thats just as important to me as the top end.
 
Nope. I'm the only one in my group that runs a redhead and my sled is no lake racer. I hang with a mountain viper ok in the deep but I have other mods too.
 
I run my SLP SXr against my buddies 700Vmax with Benders and I pull him the whole way, although the gearing and clutching are different. According to the swiss dyno guys the SLP's made the most power on the dyno vs. PI's and Bender but it's like 1-2 HP more. I think 131 HP was the best number they found...
 
jetting is also different...Benders run 150 mains and SLP's run 147.5's. The powerband is also different. My SLP likes to run 8900-9000 Rpm's and I think the Benders are more like 8600 but I am not sure. I don't have any experience with the PI's.
