Had a YFZ on the dyno with around 8 different pipes. I'll let you in on a secret.....They're all the same!!!!


They all were alot better than stock. Some had better power in different rev range but all in all if you are not looking for specific poimt in your rev range than the cheapest one or the best looking one will be your best bet.

My opinion is the one that all your mates wish they had!!!!!

Hudson powerwise maybe same but long term reliability and lasting they are all diff

all about same price so get one that will last awhile i know HMF and Leovince last well some other brands fall to bits after 12 mths or so the gut of em is crap

Totally agree. Go with a well known and trusted brand that has a good supplier behind it.

well looks like im gonna try fix mine cos im poor haha , its just where it bolts onto the header pipe needs some sort of sleev made up because it doesnt seal properley and leaks black exhaust crap onto my nice new motor haha. if that fails ill probabley just look for a slip on
