does a slip-on give much more power

[joe250]

I was looking into getting a pipe, and was wondering if a slip on will help out a stock quad very much. being 14 money is a pretty big issue. also does anyone know anything about the t-4 slip on. :cool:

this is for a 250ex i guess by ur name... i use to ride a 250ex with a graydon slip on and it really helped out alot and it was def worth it.... i think it gave it a very good increase in power...

for the 400 most slip-ons give 1.5-2 more hp.

procircuit t-4 for the 300ex has made me a happy camper
