anyone using a hmf pipe with quiet core on their rincons have any trouble. hmf told me that they dont reccomend using them due to to much backpressure. i was wondering if anyone noticed any problems of any kind with the quiet core? power loss or anything?? they also said they are working on a prototype pipe with the quiet core built in.....wonder if the core can be bought seperate when they come out? thanks for any info!!

 

I just installed a HMF pipe w/quiet core last Sat. I'm still sorting out jetting / carb issues so I can't really give you much feedback at this point.

As part of my trouble-shooting this weekend, I think I will take the quiet core out. I'll post again if I have any news.

 

come on guys i know i have seen quite a few people on here that have quiet cores on the rincons with hmf's. or anybody with other big bore quads with this set up have any probs. any info greatly appreciated!!
