We've played a little with different lenghts. Running dual exhaust makes the headers crazy (equal lenght) and all the way out ruins the backflow the motor needs. You also have to have the ECU re-mapped. Also increasing the DB's (alot). We have lenghtened ours a little, not enough to lose the backflow pressure and not have the ECU re-mapped. We have had no problems!!! Hope this helps!!!

The length that we use is in racing application. We use the extended length with the stock OEM muffler. The DB's are 93 on the meter at 2000 rpms. Yes, we are getting a bit more HP. We will let everyone know when it's available. We like to make sure that everything works great before the release of any product. We would like to race with the exhaust a little longer, just to make sure!!! Also (no worries) we have found that the flange bolts that keep the exhaust to the motor have a tendancy to back out and/or loosen from vibration. Make sure you look at them every now and then. Thanx

I was wondering if there is any jobber bolt on exhaust systems for the XTZ 1000 like the Muzzy systems for the Kawasaki Teryx? My buddy has a Teryx and his Muzzy bolt on dual exhaust sounds awesome and does not noticabely rob any power. I am not overly concerned with noise levels but do not want to rob power from the stock prowler.

Muzzys has a new dual system for the XTZ with the same features as the Teryx system. Stepped equal length stainless headers. 2-1-2 design. It gained a solid 10%. Sound testing was slightly quieter than stock.

Nice looking exhaust...what kind of power does that setup add?
It added a few Hp i think, I notice it more with the throttle responce. It is really at low hp i can gas it and get a nice instant responce.

I also did the intake, it is not all perfect just yet. one more dyno run and i think i will see a nice improvement.

I would think i should of gained a bunch more hp, thats why i want to hit the dyno one more time and make some adjustments to the fuel controller.

I have talked to a few knowledgeable owners of the XTZ and we kind of aggree that the engine seems to loose a little hp once it has been riden for a while.

I did overheat mine pretty good and blow a few head gaskets, so maybe I need to freshen up the top end?

Yep, I will do the compression check etc.. for sure. I want one more shot at the dyno first just to make sure its not some simple adjustments.

Glamis Prowler did you ever get a H.P. reading on your XTZ with the dual exhaust?

No I didn't, my dyno I used at the Pro Shop is for tuning, I dont think it is that accurate. We did get 72hp at one time.

I have had so many top end isssues i dont think it has ever been 100% with the new exhaust

Or the new exhaust took away hp, I am not really sure which
