Hey guys, I installed my Berk HFC this weekend because Im getting my exhaust done next weekend and didn't want to pay them to install them and couldn't wait lol. I know its normal for HFC to buzz a little bit at the top end but will this go away when I get rid of the y pipe/ stock resonators and throw in my resonated x with either strait back pipes or magnaflow mufflers (going to see which one I like better before welding in the mufflers).

Thanks

 

I have the same issue, I'm pretty sure its coming from the brace that attaches to the tranny, I got under there and tightened both bolts up and it got better but its still there. I think I may just take it off, just unsure if it's safe to run with out it. Hopefully someone will chime in with some incite.
