called them and they just got done and are ready to ship out there pipes, so i ordered one. you cant beat the price of $189 + 20 for the spark arrestor. also the dyno #'s are 5hp gain on the bottom and midrange and 2hp on the top end. should be here in the next couple weeks.

 

Let me know what you think. I have one for my C-Dale, but I am waiting till more Manufacturers sell pipes for the z400 before picking one out.

 

I love my Yoshi Comp slip on. Gives noticable low end grunt and sounds great

 

How's the top end smokinLTZ?

 

I just ordered my HMF too. He said I need a .175 jet with the lid removed!! Sound right?
Also said removing the snorkle was .5 hp.

 

BarelyLegal,
How much was your HMF slip on?
I emailed them and they quoted me $229 + $20 for s/a.
Dunerunner026 got his for $189 + $20 for s/a.

 

I don't know, I just told them to send me one. I'll check tomorrow if it's important to you.

 

Don't worry about checking!!
I just do not want to pay $40 more if others are paying $189

 

what HMF's site? and is HMF usually good?
