I've narrowed it down to the HMF, Sparks, and LRD. The Hetrick pipe looks cool and light but I was wondering how it performed?? Any info on these pies would be great!

 

I think you should look at the CT Racing Pipe for the YFZ450. A friend of mine has one at it runs very good, he has beaten a few YFZ's with Spark pipes and HMF pipes.

The dyno on Hetrick website looks rigged or that one kicka$$ pipe.

 

Link to the dyno.

It might be a true dyno if so i want that pipe.

 

The latest issue of Dirt Wheels magazine has an article on pipes. A shootout only for the YFZ 450. Check it out.

 

dubach and FMF were the top 2 dubach won b/c of cost and hmf was real good also but wasnt in top 5 cuz of its noise

 

That pipe shootout was a bunch of bs. They only did "quiet pipe". So pipes like yoshi, tc , thunder alley , sparks , rossier and jardine wasn't even in it. Until some of them pipes are included it isn't even worth my time to buy the mag.

 

Hetrick is an MX pipe, so if you do opposite I wouldnt get it.
