2008 xp ptek summit pipes

[slednk]

My friend was wondering wether to put twin pipes on his sled or a single pipe .... What does he need to run the pipes or is it a bolt on and go type deal ...thanks

Twins are cool but a tight fit! You will need to jet and clutch for either single or twins.

Well he is putting a dj clutch kit in an gearing it down at the same time but he doesn't need to run a digitron or anything like that

digitron... will add another 5 hp to the sled

clutching iwll need to be spot on because of the diffrent hp/trq curve they produce. Once capture properly they will work.

Pro's
Once tuned and properly setup you won't go back because it is way too much fun wheeling up the hill past the stockers
Cons
Need to send ECM to doo racing to move rev limiter because the twins run sweet 8500-8700rpm
The extra rpms are probably not going to help the already weak cranks
They beat the ever living sheet out of the bulkhead
The pipes crack on a regular basis, had to add spring tabs and reinforce pipes
Have to modify air box to let that thing breath, stock box had issues anywhere above 7000ft
Plan on wasting good riding time playing with your clutching

My experience is on a 08 xp with after market head and Trygstad ported engine with Crank Shop twins

I have a dyno port pipe on my etec and it runs flawless and and notice a big difference at higher elevations .... But I never had to do any ecm or rev limiter modifications
