Is it possible to increase the top speed of a 2 stroke ATV by just installing an aftermarket pipe with silencer? I ask because I think that if gearing is not changed the top speed would be the same. It may accelerate faster but the top speed will be the same unless the gearing is changed. Am I right or am I missing something? I ask because I have a 1985 Tri-Z 250 with a stripped stock exhaust and an Answer Hot Tip silencer and I think that it tops in fifth too fast or easy, (at least on pavement). I have heard a lot of good things about the LRD exhaust for the Tri-Z but I was wondering if it would give me more top speed if I keep the current gearing. My reasoning is that more top end is more power at top but not more RPM’s, therefore same top speed (stock gearing) but more force to pull stronger in fifth gear. Any comments?
PS. BTW I am running 14-44 sprockets with 20X11X9 rear tires (stock is 13-44 sprockets with 22X11X8 rear tires).

 

i think it would go faster cuz when my bro put fmf pipes on his banshee it increased top speed.

 

Aftermarket pipes are made and specified to do certain things. Low, mid and top end can be gained from the right one. I suppose the right pipe may let ur engine rev a little higher, resulting in a little more speed. Did you change the gearing of ur bike, knocking that tooth out of ur front sproket and downing ur tire size will make you top out faster and have a lower top speed. If u did it for low end then its fine though. You have to sacrafice pulling power for speed, and speed for pulling power.

 

it depends on your redline. if the motor now has enough power to pull to redline then you won't see any more top speed. however if you still have any Rs left at WOT then the extra power from the pipe would help you out.

 

I put a pipe on my trailblazer and it increased the top speed by 5 mph
