did anyone notice that the car lost 4-6 hp when they put on the HFC compared to the dyno with just the 12 inches resonator???

No. The catback alone made 301rwhp. With HFCs it made 305 rwhp. With test pipes it made 310 rwhp.

Is this with stock intakes?

Thanks.

Yes

do you have any videos of a car with stock cats and the non resonated x pipes?

I have not built it that way yet. In fact, no one has ordered it with a straight X Pipe.

All PM's replied!

hmmm im wondering if without the resonators its going to be raspy and drone alot..
