hmf/rossier

[KOG]

witch one do u guys think is the best i know there both good just wondering what on has the best gains

[Mobile Dyno]

I would recommend the Rossier. Great Power through the entire powerband. The HMF is also a good pipe.

Both are great pipes, I have the Rossier and I really like the way it performs. I am sending my head to him today for the port and polish.

Ive run both, and while both are good the rossier would get the nod from me.

I run the rossier but I think the HMF makes more TQ but is loud as hell
