Bkm2006 Posted August 5, 2011 Report Share Posted August 5, 2011 Most common is t5 I believe toomey's website has descriptions. I bought my bike with t5 but if it was my money id go with CPI Quote Link to comment Share on other sites More sharing options...
bigblockbanshee Posted August 6, 2011 Report Share Posted August 6, 2011 whats the performance difference between the t4, t5, t6 pipes on a stock engine ? on a dune ported engine ? which one is best for stock eng , pump gas ? modded engine , race gas , milled stock head , dune port ? From what I've heard: T5 is just an updated version of the T4, T6 is best for being first bolt-ons for a stock bike, i.e. no porting, no big-bore or stroker motors. I don't have personal experience with the 4s or 6s but my T5s run strong IMO. Personally, I never understood how you could mass-produce a pipe (T6s) that wasn't made for other mods such as the ones I listed because everyone knows that you can't just stop with pipes and jetting, it eventually goes way beyond that. Again, this is only what I've read on here so take it with a grain of salt I guess. If it were between only these 3 choices it would definitely be T5. Straight from Toomey site: T6- This all new pipe, designed specifically for the standard non-modified Yamaha Banshee Engine, creates more low-end and mid-range power AND peak power than any other pipe design available.

bellracing2 Posted August 6, 2011 Author Report Share Posted August 6, 2011 thats what most of my riding is , 75% tight trails , 15% logging /fire roads , 10% dunes . currently I am just a head mill with +4 timing . I need a good reliable bike that uses pump gas 93. Quote Link to comment Share on other sites More sharing options...
volcrano Posted August 7, 2011 Report Share Posted August 7, 2011 pro circuits are nice for trails,they build power quick and still pull nice up top.if u want a pipe from toomey,t5 if u have plans of porting (which they still run nice on stockers),or t6 and like cam said have it ported to the t6 pipe.my buddy has his ported with t6s and it rips real nice.if ur going dune port id go t5s,but if ur riding 75% trails u shouldnt be getting a dune port,more something like a hardcore mx port/aggressive trail.
