yfz exhaust question

[foxbud]

so i have a 06 yfz450 racine xc and it has a gytr slip on and im looking for the best exhaust should i keep it or get the hmf ballance or sparks?

I am running a Ballance pipe on my YFZ and even with a DB Dawg it registered 101, so you may want to check if your race series has a noise restriction. I had heard Sparks was working on a quiet core, but every one I have ever heard is louder than my HMF uncorked, which by itself could make your ears bleed:eek2: HMF does have the QRS series which should work well.

i saw a sparks this past weekend and it was pretty good sounding, it did well drag racing but idk what else was done, i have a sparks on my trx 450r and it is a well performing pipe, i wouldnt be afraid of buying a sparks.

hmf ballance is the same as hmf sport series, you are just paying for bill balances name. im not sure about the yfz but i head the 450r's best pipe was by dasa.

i have used the yoshi system from titanium to stainless,they have an issue with rivets falling out and the head clamp (aluminum) bending and causing leaks.in 3years im on my 3rd.it makes great power but it is a pain to maintain.friends use the alba pipe and the moto4 pipe great success.what ever pipe you choose check clearances to full bottoming out.some hit others melt the plastic.
good luck just my 2 cents.

i think the best would be the tc racing its loud but its the best flow

How is TC the best flow? Not a hateful comment just curious. I really like my baldwin system it has a real smooth curve and tons of pull.
