i've been considering hfcs and a catback true dual system, but i want to know a couple things beforehand.

i've been on the 35 board for a couple years and read about droning on a few aftermarket exhausts and wanted to see if anyone here with an aftermarket system is getting the same, especially at highway speeds or medium throttle.

 

no drone with just HFCs.

I have heard others say that they also get no drone with HFcs and exhaust.

 

sweet. i think im going the fast intentions route.

 

If you are 6MT you will forsure be fine... i even have test pipes and dont get drone... ask solo since he has the setup and hes a 5AT

 

I have FI HFCs and Intimidator catback system installed

Cruising at freeway speeds I notice NO drone whatsoever.

65mph = approx 2500rpms
70mph = approx 2750rpms
75mph = approx 2900rpms

I have the FI Exhaust and the FI HFCs and there is no drone at all. Go for it.

 

wonder what the RPMS are for auto...

 

it has a lot to do with the exhaust system you are running. it seems that most people are running here are on the mild side so people are having no issues. when more aggresive exhaust systems come out you will see a lot more with drone...

 

I was running 80 MPH today at roughly 3100...

I could here a faint exhaust sound from the rear but it wasn't a resonating drone.
