shortened exhaust can???

6 posts in this topic

i've read a couple times now that a shortened can will increase the bottom end??? i've got a powercore 4 that seems a little long to start with,and shortening it would be very simple the way it's designed. how much should i take off??? it looks to be around 18". i'm guessin' about 4" ? :cry:

I don't have an answer, but if you find out and are successful please let us know. I have Powercore on the way. I think the biggest problem with my 05 WR so far is the lack of any real bottom power. That really surprised me.

I have the materials on the way to open her and rejet, I'm sure that will make her faster, but I doubt it will give any more bottom end power... we shall see though.

My understanding is the larger volume can is better for bottom end. See the latest pipe test ( link below) and you will note the Ti4 and Ti 4 AMA legal only difference is the length of the muffler and core diameter. :cry: Now If I can just figure out how to make mine longer!:cry:

FMF Ti 4 has the most low rpm grunt of all the pipes!:cry:

"the difference between the two FMF ti4 exhaust lie in the length and core diameter,the STANDARD having a SHORTER can and larger core. the STANDARD produces MORE bottom end." you misinterpeted:naughty: ...:)the way i was thinking of enlarging the core was to make a sleeve of ceramic cloth batting(good for 3200 deg F) and wrapping in a perforated stainless tube,leaving much more room around the core section.

That is a very powerfull weed whacker. Any possible way to get the upside of 50 horsepower? ? How about some torque ratings? It would seem more important to have more torque than horsepower. Am I wrong?
