ALBA, old style. I had one on my DS and it ran and sounded awesome.[img]i/expressions/face-icon-small-smile.gif[/img]

 

good one Chris!

 

i always wondered about the aaen pipe, has anyone ever heard of a person running one of those?

 

Olav builds most of his pipes per order. When I asked if he had the pipe for DS650 on a dyno, he said no.
He has switched to making his systems totally out of steel and he can get the system ceramic coated. The lead time on getting it coated was three weeks. He is a Polaris guy at heart and is trying to branch out. He has a dyno, why he does not tests other brands systems!!!!!!!!!! Very nice guy to talk to, the theory behind his systems has merit, I just prefer to see real data.

It was a toss up between the AAEN and Thunder Alley when I was looking at pipes. I had a friend that had an AAEN on a Predator and it ran good, kind of in between the Pure Pipe and an HMF for performance on the Pred.

After some research the Thunder Alley looked to be the better option of the 2 for the build I was working on, so I got the Thunder Alley.

I think i might try out that Rocket Exhaust, its the sharpest looking of the bunch and i only want a slip on

And DMC does not make one, they have it on their site but never went into production wit it, just got an email.
