XPL Coffman pipe...what else is in this picture
looking to get a coffman pipe for my xpl. im sick of the 2 piece stocker and looking for more topend
ive been reading and it seems that you need a microtouch rev limiter and microtouch water injection to run the pipe, as well as jetting.
my question is does this pipe here include the microtouch parts i need? am i missing anything?

I would go with a seadoo white pipe found on the 97.5 gsx limited unless you like replacing pistons. If you do run the coffman, you will need to depitch your impeller as most running that pipe are running a 15/19 concord.

i already have the white pipe head pipe. im looking for the coffman or another exhaust because it is one piece. it will be easier to install/remove when i do work on my ski
the seadoo xpl stock pipes in my opinion are a horrible design. from how they bolt to the y-pipe and how they are 2 pieces and sealed with a dinky band clamp.
im just looking for info on whats needed besides jetting for a coffman exhaust

Jetting, Rev limiter, ECWI, Flame arrestors, new or repitched impeller..
To get the full benefit from the pipe

well i already have the impeller and flame arrestors. jetting is no problem
my question is does the pipe in the pic incluide the rev limiter increase and water injection controller? im not sure what they look like

It is missing the flange and has a 98 rev limiter. The correct cylinder porting really makes the Coffman XPL pipe work well with the stock carbs. If you want to run stock cylinders, Novi carbs get the job done. A remapped Coffman curve mpem from Tim @ novi w/ a higher rev limit is the way to go on the "rev limiter" requirement.

I ran Coffman pipe on big bore stroker for years, never had a problem with pistons.

Im thinking as long as i take my time to tune it in, it wont eat pistons, just like any motor mods.
so it looks like that pipe has the water injection, and i emailed the guy and it does come with the flange to mount it.
I understand id need my mpem remapped to raise tw rev limit, is there anywhere beside novi to get that done?

Or who do you guys reccommend for porting my cylinders? I just have a feeling if i tear down my motor and get it ported, i wont be able to help myself from just doing a 1050 lol
